I would like to see a follow up video of after you returned the ccv to stock and see if the smoke went away

My truck has been perfectly fine with the ccv. It’s been on for years and my truck has never ran better. No leaks or anything. So thank god i am not taking your advice on this one.

Internal combustion engine breather systems are one of the most misunderstood systems there is. So simple yet so damn mysterious to some. There is absolutely no harm done to any engine that simply vents to atmosphere.

A road draft tube works on a semi truck because the gases are being released at the crank case. A 7.3 has to have its crank case gases go out the valve cover that’s why vacume is needed from the turbo

@@alshegarfi7338 Again, this doesn't make any sense, if the the crankcase is pressurized and there is an indirect line to the ccv system through the valve cover the pressure will be the same in both locations. This is pretty basic, pressures in 2 vessels that have an open connection will passively equalize. It's the same reason the high pressure oil system has an equalizer line in the middle of the valley on a 7.3.

Bill, do you consider it a bad idea to do the CCV reroute on the 6.7 powerstroke engine as well? Just wondering as I'm considering doing it but really don't want to deal with these issues if this is the case on the 6.7.

maybe the crankcase ventilation was connected to the exhust pipe that is why it was smoking ...

I did the this to my 99.5 PSD 7.3 10 years ago, With no problems! Ran the Hose all the way to the rear of the truck. My Intercooler is clean with no oil any were!! I now have 215 K on the truck with NO PROBLEMS!!

Hearing a Powerstroke rev like that makes my pants tight.

I understand what you're saying, but I have seen diesels that vent the crankcase right to the atmosphere, (i.e.: Cat C7's and DT466's), so how do they get away with it?

Big facts the stock system will work fine on a stock truck but put custom cut pistons and set the rings for high boost and let me know how much oil runs through the turbo or intake this isn’t just for Diesel engines either

does the turbo require smoky blow by oil to stay alive. or the seals just give out cuz of the tad bit extra crankcase pressure that occurs when vented to catch can

My 2002 was stock with 175k miles, oil coming from all the pipes etc...I had no idea what was leaking and what wasn’t lol .. did CCV mod cleaned up the engine and fixed the found Leaks and seals and gaskets and hoses etc...

im haveing no problem I did my own bulletproof just sent my heads to my machine shop to do O rings and bronze valve guides I'm putting out 650 horsepower towing a bobcat everyday for three years now still no problem Bill did help me with alot of his knowledge thanks

My 6.4 started blowing heavy white smoke as soon as I added the catch can to it. I checked everything under the hood out and it all led back to the ccv delete. I put it back to stock and took it for a test drive. All the white smoke stopped and the excessive blow by is now gone

I got NO TURBO; what happens if I disconnect the crankcase breather on my V6 from intake housing and let it hang downwards on its own.( but I plug up the air intake housing hole).. will it affect the engine?

what about the 6.7 powerstroke with the EGR caking up? any advise on that? do you recommend that CCV delete on those?

I have my plumbed to my exhaust. Still creates a vacuum but no oil in the intake. Watch Anthony Youngblood from super duty service, he does it on all his builds.

Question if you removed it replaced it with a catch can and left it plumbed the same way what do you think

Mine is stock. Just saw I have some blowby with a little bit of puffing pressure. Is that normal? Doesn’t blow oil cap off but just a couple months ago I had none.

hi Bill I have this modification on my truck however mine is more like a catch can that I can drain it's still hooked back to the intake pipe do you think this would be ok or should I do it with my catch can

I have a 2004 6.0 and I have an excessive amount of oil in the tubes as well as pooling on top of the engine,so much it is coming out on to the hood.I can't see where the leak is coming from. The engine runs fine. Advice?

I saw a test on an engine where they tried several variations of a ccv system and the engine made the last power with no ccv system. Better with a vacuum system and made the most power with a belt driven vacuum pump. Even with the load of the pump, the horsepower was still higher. Keep giving the good advice.

I did this in my 6.9 idi I heard it caused it to blow my head gasket so should I put my cdr valve back on?

I bought a 2000 School bus with a T-444E(190 HP) in it, that has a RACOR device on top where the CCV hose comes out.. from this RACOR there is a hose going to the Intake Past the Intasle air filter and Before the Turbo, are you familiar with this deivce? or should I take it off and replace it with a stock CCV hose? Ive not seen one of these on a bus or sure what its purpose is.. although I do know it leaks oil around the base of it so ive got to take it apart and see whats leaking in that RACOR..

Hi, (1999.5 7.3L) My Turbo Pedestal Small O-ring fell into the Hole next to it while upgrades.. I was distracted and I saw it fall in to the return hole. What should I do? Any help please :( I used an endoscope and nothing..

Do you guys do any kind of financing on repairs and dealer proofing?

If the green O-ring or the hose has a leak, can it cause a P0401 CEL code?

I just bought my first diesel. 1996 F250 7.3. I thought I had a really bad engine leak cuz smoke was coming out underneath my driver side. I follow a hose up that's just blowing out smoke and it appears to be this ventilation on top of the valve cover. The owner put a d66 turbo on the engine. Don't know if that's an upgrade or replacement. Is there a place to plug this hose into that style of Turbo? I really don't want to suck fumes all day

You said increasing this crankcase ventilation puts stress on the turbo seals. I assume you mean the increased crankcase pressure? Which by the way I don't believe would be an increase or a problem at all. But my question is, how in the world would that pressure affect turbo seals? The turbo return oil drain? No way air pressure is traveling against returning oil. And no way there is such an increase in crankcase pressure just from leaving the ccv hose open to atmosphere. Unless it's plugged up or kinked, there will be no problem.

I had an 05 6.0 hat I vented to atmosphere and the hose got kinked making it white smoke profusely. I believe people restrict them too much sometimes when they vent them thus creating pressure inside the crankcase and thats why they smoke. Restricting a ccv will make them blow seals. Just got my second 6.0, a 2006, routed it to atmosphere using the stock fittings and a length of 1'' heater hose. No problems so far. Just don't choke it down and you'll be fine.

Some of us live long enough to realize the manufacturer does know some about what they build.

Usually this guy gives good advice but this time is no bueno...He even states "9 times out of 10 the leaky turbo stops after we re-route the PCV back to stock, I don't know why that is..." - then you shouldn't be commenting on it Bill. The only reason FoMoCo routes the PCV this way from the factory is for emissions. The small amount of vacuum is negligible at best in evacuation the crankcase and that 5/8" ID hose vented to atmosphere does a fine job. Not happy with that? Weld a bung in the exhaust and have it sucked out that way. Vented externally, you clean up the intercooler (increasing it's efficiency) and don't have oil seeping out all your charge pipe couplings, as well you're not caking up the backside of the intake valves (assuming you have an EGR delete done) and pistons by burning this condensate.

a crankcase ventilation is used to prevent pressure build so your orings wont leak cause of pressure build up right? so if you disconnect how is it harming it if its still relieving the pressure air will flow in the path of less resistance right? so how would it have any bad effects to the orings if its still relieving the air by pressure?

Because the vacuum from the turbo relieves the crankcase pressure more quickly.

I've always wondered about the crankcase pressure issues this might cause. I don't have as much of a problem if someone uses a catch can to reduce atmosphere venting, but the vacuum issue, im curious to see. Might do a little test by watching venting from oil cap, see how much the CCV pulls through its path. GOOD ADVISE BILL as always.

Not sure about a 6.0 but on a 7.3 the ccv mod causes no problems. In fact the International T444E (same engine as a 7.3 Powerstroke) used in commercial trucks has the crank case vented into the air.

Yeah but there's more benefits to having vacuum on the crank case vs no vaccum..vacuum... in race engines they make vacuum pumps specifically for sucking out crank case pressure and some claim it seals the rings better and creates better compression. Will you get that with manifold vacuum? Probabably not but there's no harm in running vacuum. Having pressure is more harmful so why risk it? A little oil consumption adds mpg anyways so why not?

CCV mod is very good. Just be sure to use at least a 1" diameter hose at a constant slope. This reminds me of the snake oil comment persons that railed against additive such as Arch oil and Revx. Come to find out those mechanics and followers of those mechanics comments, or as I like call them peanut gallery followers, couldn't have missed the boat more. Yes it cuts into profits of unneeded repairs and perfectly good solutions to not spend thousands of dollars plus extra down time towing etc. If doing any mod or using any additive, take the up front time to investigate why it works and how. We know using snake oils can work if the problem is fixable by that science. By using the thought of suction removes more blow by, then one would have to worry about to much suction. That could suck more fuel into the oil pan diluting our oil with fuel much quicker. I am not saying the EPA system to scrub the emissions does that. Of course we all know the EPA doesn't care if their approved systems ruin our engines faster or not. So if you do the CCV mod and it causes your engine to not vent properly, Then you have not done it correctly. Check hose size. 1" diameter works real well with my SCT tune on heavy tow and make sure it runs out at a constant slope with no kinks so it doesn't create a pool of build up oil clogging it. I also added Ia notched on the dump end in a forwards facing V. This does create suction with forwards movement. I learned that years ago while having some work done buy a shop working on my 379 Peterbilt by simply asking why the hose was that way from the factory and noticed other trucks not. If you still have problems after that you have another issue. Do it right or don't do it at all.

I have always been impressed with your mechanic skills and your knowledge and I have enjoyed your videos, most of them are full of great information, until this one. my last truck was a fully deleted 6.0 and my family's company has 6 of them. I've done this mod on all of them, and I think it's an excellent mod. It keeps all the intake tubing dry and clean of oily and dirty debri. We I have always had a problem with oil seeping out around the tubing in various places and as soon as we did this delete we quit having an oily mess both inside the tubing and outside the tubing, how can that be bad? As as far as vacuum needed to suck that stuff out of the crankcase, that's BS there is plenty of pressure built inside the crankcase to relieve itself there's no need for vacuum or sucking of any kind to get the pressure and oil out of the crankcase. And if this is such a bad thing to do on diesels then explain to me, while right up until emission started to be a big deal to SOME, diesels all over the place vented out of a vent tube that dumped right out below the motor, they were all set up that way. The Cummins in the Dodge pickups dumped right out blow the motor up until mid 2007, all your tractors farm equipment big trucks forklifts and such all dumped out right below the motor straight out from the crankcase similar to the vent setup you have in your video and if it wasn't for the EPA and their bull crap and all the emission talk about the planet burning up, the crank vent tubes would still be dumped right out underneath the motor instead of recycled through the air intake.

You are right I would leave it stock in a diesel. The gassers with direct injection have issues. My buddy has a Mini which oil from his intercooler slosh into the combustion process, create unexpected combustion, and the sensors would detect irregularities and throw him into limp mode. He added a ccv oil catch can to catch the oil, but the gasses still fed into the turbo. He empties the can about every 10k, so far with 30k on the mod, hes been problem free. My guess, is this is crossing over to the diesel side where it isn't as necessary.

so i need some help figuring something out. im looking at some box body ford diesel trucks within the years of 1990 and 2000. im not looking for something for pulling im more of looking to make a drag racing truck. im gonna get a 7.3, i know alot about power strokes but honestly i really dont know much about the IDI diesels. so im just trying to figure out what would be a better pick for me, the 7.3 powerstroker or 7.3 IDI. i want something that will have alot of parts options online and i dont wanna be constantly repairing small parts on the engine.

Guys- he cant and won't tell you to void the warranty or bypass the emissions on your Powerstroke. His job is getting your Powerstroke back on the road.

Incorrect. A rod draft tube works on a semi because crank case gases are vents at the crank case. A 7.3 had to vent at the valve cover. That is why a vacume, not engine vacume, from the turbo is needed. If u pay attention to the tubing for the turbo, the orface for the turbo is smaller and the orface towards the the filter is bigger. This is on purpose to create a Venturi affect.

I would love to know how you could explain how all the turbo chargers since the beginning of time on diesels with crank case vent venting to the outside survived if this is what’s causing your turbo problems.

Plus in the great salt belt when winter comes around the moisture in the CCV will freeze and can block the line up. That'll blow out all the seals in the motor in a hurry.

Just wondered if these CCV re route kits were a good idea.

Got a little black smoke on a mild take off. Go to tuner roll back low presure fuel by 1. They are pre set to 3. So a setting of 2 should keep the black down just enough.

would a oil catch can help catch the oil from the ccv? also would it help to catch that gos in to the intercooler?

I guess the vacuum in the crankcase does a pretty good job at the turbo. It sucks at the chargers drain line and reduces effective oil pressure at the turbocharger bearings. Positive pressure in case of bad ventilation would be really bad and even increase the pressure there.

Take a 6.7 CCV filter out and pick the material apart. I doubt it's actually relieving pressure in stock form either.

If this is true, then why does every VT365 I have worked on vent down by the bellhousing? How can an 06 dodge Cummins 5.9 vent to atmosphere "safely" but a 6.0 can't? every other diesel engine/manufacturer on the planet goes by the rule of , if there is oil in the CAC system, then something is wrong.

Because the crank case is being vented at the crank case. A 7.3 has to vent at the valve cover same without the 6.0. That’s why a vacume from the turbo is needed

Statements, and a Question! Statements: My coffee cup doesn't get sticky or weird, until sometime after I stop adding fresh coffee. If it were day one, I would vent my 7.3 to the atmosphere! However, right now (per my inspection of an intercooler pipe) what I have is Clean, Wet, Fresh oil... presumably throughout, the affected components, but at the very least, downstream of the turbo--which I'm okay with! If I stop refreshing it then, it will be moving toward Old, Dry, Dirty junk. Question: Am I crazy?

I lost brain cells watching this

How do you feel about catch cans?

I did the ccv reroute on my 97 7.3 and it immediately went to smoking. It started to drip oil out the tale pipe. Put it back stock and stop smoking so in my case he's right.

I just bought a 2012 with a 6.7 and at idle I would smoke a inter section out with white smoke. This is after a full delete on the exhaust. I put the by pass on and found the previous owner had 3 gallons of oil in it. I drained it all and put the required 13 Qts in. Now I get some minor white smoke from the bypass. Plus the CCV was causing oil all under the hood and engine bay.

Good thing mishimoto just fixed that issue 😂😂

Please explain how the CCV has anything to do with the exhaust wheel on the Turbo?? What really happens is you need negative pressure in the crank case to help keep the oil control ring doing its job on the piston. You will have increased blow by which burns out the exhaust and goes out the turbo nothing to do with seals on the turbo.

So with the mod you had about 653k? Sounds like something was working right. The mod has to be done right. If you had 1" hose v notch forwards then not a problem. You must be hauling heavy loads. That will eat turbos as it should be your weakest link before engine melt down. If you wear out seals you will first notice turbo weeping and then oil dieseling that can lead to run away. You should have looked into or you may now have a properly built turbo to get longevity while doing heavy to over demanding loads. Cheap rebuilt turbos abound and commonly fail during normal use. Therefore buying a new quality turbo especially if you make your living with it is best.

Please explain the physics behind a blown seal on the turbo shaft being caused by the Crank Case vented to the atmosphere versus a mild suction to the crank case. The pressurized oil system is sealed. The hot air, if you will, is still not pressurized because it vents out. The suction would only affect the gasses that get by the seals of the cylinders. Those gasses will get blown by regardless of a mild suction or venting to the atmosphere. What I will give you is the oil will get soot and other combustion particles contaminating it sooner, but that is negligible. I'm at 7,000+ miles since my last oil change and the oil still looks good and I have YET to add any. And yes, I have blow by. I actually have to replace my CAC boots soon. Oil residue is showing on them between the turbo and the cooler and at the turbo air intake. Stock truck. I've been driving semis since 2009. I've driven new ones with 23 miles on the odometer and ones with a million plus on them. Never had a turbo seal go out on ANY of them because they were venting to the atmosphere. Again. Explain to me the physics behind a sealed oiling system blowing out a seal SOLELY based on a CCV not having mild suction. It can, and WOULD, blow out from a OILING problem. Such as turning off a hit engine and turbo, thus coking the oil in the turbo. Gumming up things like the turbo oil drain tube. Which would cause over pressurized oil to the sesls in the turbo.

Bill, why would you need to replace the turbo if the seals blow? New seals come with every single rebuild kit.

Let me try to get you to answer me one question because you never return my comments, do we have to clean the factory ccv system and how? Thank you sir. Great video like always.

As much as I love PSH videos, it's worth noting that the 7.3 was not a "Ford" motor. But you know that. If you haven't taken the time to look, look at some of the REAL 444E applications. DT444E from Australia, maybe in a BUS.. Real heavy GVW rigs.... Many have crank venting through a separator can & out behind the engine, or straight our down the bell housing... Any that DO vent into the intake are FIRST run through a air/oil separator can so IT DOESN'T FILL YOUR INTER COOLER WITH OIL ! A leaking turbo seal is just that, LEAKING! Just because applying vacuum stops the leak doesn't determine it was the CAUSE of the leak. Hell, maybe your blow bye is shooting your dip stick out, but when you hook up the CCV vacuum up, you just FIXED the blow bye ? Light neg vacuum can keep a slight leaking gasket from dripping, but there not related as cause & effect You will NOT build pressure in a crank case by venting wide open .. BTW, Aviation engines NEVER gulp filthy crank case gasses, they always vent to "atmosphere"

Also if oil level rises from leaking injector or a fuel line rupture it can and will cause a runaway to happen. It happened to me..

The ccv is clogged

bs on it blowing the turbo seals... older heavy duty trucks and off highway engines vent right into the atmosphere... the recirculation is purely for emissions

What about using a catch can?

Awesome vid!! You just stopped me from doing that mod!! Thank you!!

Wow - get a shovel cause this is getting deep. All venting the ccv to atmosphere does is keep your truck out of this guys shop. I think that is a fine idea.

Respectfully, I have to disagree with you. Sure,venting into the atmosphere is bad, but if you live in warmer/hotter, drier climates, the hotter air cannot pressurize as much, so the engine runs hotter. This increased heat and pressure results in excessive oil condensation. So, why is that bad? That means that, instead of your turbo reusing burped condensation to increase pressure, and properly vent separation gases via the exhaust, the crankcase is creating a negative vacuum situation. This will result in the case burping hot gases into the custom tube. Now, since we take the pressurization of the crankcase away, the pressurization reaches a stop, and so instead of feeding all of that hot air down a non-pressurized exhaust tube, the pressure comes to its exhaust point via the exhaust manifolds. This will result in bellowing white, burnt-oil-smelling exhaust from your tailpipe. These plumes of white smoke from the tailpipe will get thick, and allow you to breathe in the NOx; they will also dust all cars behind you as well. TL;DR: Don't reroute the crankcase into a negative pressure situation (to open air) on the 6.0 Powerstroke. It will completely obstruct power output, which will result in overheating, and much, much, MUCH higher oil condensation gas burping.

Bill, you are partially right here. The crankcase vacuum is important as gasses do get past the rings and into the crankcase. The gasses that get into the crankcase are not good for nearly everything in there. Over time they will react with the various metals and oil, as well as dilute the oil itself. The CCV is a simple way to ensure a moderate amount of vacuum sucks out the denser gasses which could otherwise settle and not be able to escape. Ford should have put an air oil separator on these trucks. Anybody who has a high horsepower Subaru knows this as well: up to 600hp or so, most air oil separators will route the vented gasses back into the intake. IAG's competition series AOS does not, but the disclaimer specifically states that oil change intervals must be dropped to around 1,200mi or after every race, because of oil dilution.

That's what the ccv is. Air, oil separator.

@@RoadKing05FLHR there is no separation on powerstrokes. Simply crank case vent. Lots of people including me put catch cans. This allows crank case pressure to recirculate through the turbo without the oily mess that over time caused other problems

What about carbon fouling of the intake valve.... this is a real big problem with direct injection turbo gas engines, and so then itd make sense itd affect diesel valves as well.

the turbo is not sucking on the crankcase ventilation tube..so we are creating just a tad bit more crankcase pressure than normal so the seals in the turbo give up.

The intercooler is designed to have oil blocking it up? 😂😂😂😂

Oil doesn’t plug it up. The motor burns it. A road draft tube works on a semi because it vents at the crank case. A 7.3 had to vent at the valve cover, which is why the CCV mode doesn’t work on a 7.3. Ethier leave it alone or put a catch can setup that adds to the existing desighn.

love your videos brother.

i did the ccv mod and i had put it to my down pipe at an angle and it works great.

I’m here to tell you very little oil is exiting the CCV box. At 219,000m, my 11, 6.7, f250 doesn’t use a drop of oil between changes. I replace the CCV box every 50,000m but unaware if there is a recommended change interval. I think someone once told me that, but not certain? If anyone knows the answer please comment. I don’t see any need to delete the CCV box. What is the gain? It doesn’t fail, you don’t get additional fuel mileage. What is the upside? I’m 70 and for the most part have always erred on the side of original engineering. I’m not qualified to anticipate unintended consequences of alterations, especially the complex diesels today.
