I own a 2016 Equinox with a 2.4L with just over 100,000 miles. I bought it new in 2016. Last deep freeze in December 2021 my PCV system plugged up and blew out the rear main seal dumping 5 quarts of oil instantly on the highway at 70 miles per hour. Of course the motor was destroyed in a matter of seconds. It bent valves, wrecked the timing chain, etc. I called my Chevy dealer and they said "Sorry your out of luck." , but yes there is a technical service bulletin out on this but you are out of warranty. My only choice was to dish out about $4000 on a junk yard motor and installation. This is a very common problem. I wish they would of at least had the decency to send me a letter letting me know about this issue so I could have easily prevented it. Since this happened to me a few weeks ago I found this car is on the list for many other issues including paper thin frame underneath which rots out in about 8 years, timing chain issues and a few more. I am afraid to drive it now so I traded it in on a Dodge Caravan. No more GM / Chevy for me.

Very good video, but just curious, why couldn't you just cut the existing line and splice the line running from the existing valve into the new line running from the oil cap, through a collection can and then back into the existing line feeding the intake? This would remove the water/oil from both PCV valves using a common collector can. I am buying a 12 Equinox and this is how I would like to do it, because I feel the oil cap PCV will not fail as easily as the factory one. I just was curious if there is a reason you can think of that this method wouldn't work? This whole process would take under an hour to complete and I would think it would do the same thing. I saw on another video where someone spliced a can into the existing line, but you are still relying on that tiny hole on the PCV end not plugging for whatever reason, so I feel 2 PCV valves is the way to go.

@Frank4358

The OEM PCV is a tiny, 1/8" orifice in the middle of the intake plenum. No way to splice in. By installing a fitting at the bottom of the intake runner you don't upset the vacuum signal to the cylinder head. If you splice into power brake vacuum line you run the risk of contaminating the power booster with atomized oil. The oil cap I used was a Stant oil cap. Stant is the OE supplier to GM. So there's no fear of a cap failure. I used a Bridgeport vertical milling machine to spot face the replacement cap. Then I centered the cap and drilled a 0.750" hole to accept the grommet for the PCV valve. I coated the machined surface with dielectric grease before installing the grommet. Then I added a small amount of dielectric grease to the PCV before inserting it into the grommet. There is a baffle between the rocker arms and cam to prevent splatter into the PCV. I would also recommend a dollop of RTV around the fitting you install in the intake runner.

Im currently working on a 2013 equinox 2.4 liter with a vaccuum noise unless oil fill cap is removed. Cleaned intake and PCV hose to air box. Also replaced valve cover. Had to drill a small 1/8 hole in oil fill cap. Did yours make a noise before you did this added port to the intake. Its definitly vaccuum and not crank pressure.

The whole idea is to take the oil and vapors from the engine, and return them to the combustion chamber to be burned off. If you add a catch can between the PCV and the intake manifold you defeat the emissions system. As far as adding a T-fitting to an existing vacuum line, I've discussed that in a previous comment, but here it is, again; The only line that is large enough is the vacuum assist for the power booster.

@@Frank4358 you simply dont know how the brake booster works. It runs on vacuum, one way from the booster to the intake. It also has a one way valve to prevent air or vapor from entering the booster. Running for over a year, no issues. Putting a catch can on that line will collect a large amount of oil and pass the vapor. I have collected over a quart of oil in the past 15k miles. If your not using a high efficient baffle and filter media you will be sucking in a huge amount of oil. By putting the fitting where you did, most of that oil will be sucked into the runners of #3 and #4 cylinders. Using the brake booster port centrally located it will be dispersed to all intake runners equally. Also not blocking off the internal orifice you fefeat performance and function of the PCV valve. I used a custom, adjustible PCV valve, blocked the port, installed catch can, and tapped the brake booster hose. I get a constant .1 inHg a vacuum in the crankcase at all engine loads which is more than enough to ventilate the crankcase.

The alternate PCV draws the pressure out of the engine into the plenum and then burns the fumes harmlessly in the combustion chamber. If you remove the oil cap you will see a baffle under the cap that prevents oil splashing back on the PCV. The reduced crankcase pressure alleviates the blowby, thereby eliminating the oil consumption. After performing this modification on my engine, all oil consumption stopped.

We tried several things than switched to Amsoil's top oil, Signature Series, (I was reluctant because I was paying for it) and Amsoil micro oil filter.

I kept calling Cy, vehicle owner, asking how it was going. 1 day later. 2 days, 3 days Response was positive each time. It coded once for VTiming but did not stall out like it normally would. It started to stall out once with no code two days later. We kept using the additives every fill up. PI is to use twice in beginning then every 4 000 miles but we used it for next 8 fill ups hoping it may help, then every 3rd fill up. Use upper cylinder lube every fill up. It was a shot in the dark but a year later it was still running good and not using oil like before.

Hi Frank, last year I installed a separator into the clean side of the PCV system, and it works well and does not freeze up. I have captured quite a bit of moisture and oil. Only occurs at high speeds and moderate loads where intake vacuum is very low. GM designed the fixed orifice PCV system to prevent flow variation of standard valve. Makes for programming the ECU fuel/load maps much easier and reliable. The cleanside operates to pull crank vapors at high speeds and low vacuum. At idle and low speeds in the city, the fixed orifice does a good job of keeping crankcase clear. I was expecting see a lot of carbon and "gunk" in opening of the head but it was clean from your video. Did you block off the orifice? The only time I get build-up on the cleanside tube and reservoir is during highway driving, low vacuum and high moisture conditions, such as raining or snowy weather. Did you take any vacuum measurements in the intake or pressure in the crankcase, before and after. Just curious to compare. Can you connect a vacuum gauge with a long tube and check the reading at highway speeds, up and down hills and flats. I am considering a similar design. How did you select the PCV valve? There are dozens of PCV valves with different flow rates and specs. Getting too much or to little could cause problems for the engine in the long term. I am considering a ME Wagner, dual stage adjustable valve that you can calibrate for the need (size, vacuum specs, and performance of your engine. It uses 3/4" grommet opening, same as yours and should connect to the your 3/8" hose easily. Check it out.

That tiny orifice gets clogged, as well as the return that accumulates moisture then freezes. Before I did the modification I removed the oil fill cap and found an amazing amount of pressure blowing out. I checked the PCV return line and it was clear. Now that it's modified the pressure coming out of the oil fill cap is negligible. When choosing a PCV valve size was obviously a concern, and the one I chose was compatible to other 4-cylinder engine applications. The engine operates as designed with no major concerns for vacuum variation. Cold start, and warm engine idle is actually about 50 rpm lower now; both in drive or park. At cruising speeds the engine also operates at a slightly lower rpm as well. No additional programming or remapping of the ECM was needed. I hope this answers your questions.

What oil cap did you use?

I own a 2012 Equinox with this engine, and I need to point out 2 things. 1. Years ago, cars had a small filter just inside the PCV connection to the air intake which stopped oil from getting into the incoming air but allowed the crankcase gases in to be burned for emissions control. I'm not sure how you'd add this to the 2.4L, but I think it would be easier. 2. The engine in this video sounds like it's low on oil. Based on my experience (210,000 miles), the engine should run MUCH quieter than that with a proper oil level. When this engine gets down to 2 quarts (that's 3 quarts low), it will knock, and only adding oil will fix it. As for PCV pressure, this engine has 11.2 to 1 compression (high for gasoline), which means the combustion gases will have substantial pressure both at the exhaust valves and in the crankcase. If you suspect an oil leak, check the seal around the oil pan, and the oil drain plug. The factory oil pan seal is not a gasket, but a sealant. This can develop leaks.

@Frank4358

Жыл бұрын

The filter you speak of was a foam filter that was installed inside the air cleaner assembly. There's a baffle under the oil cap that deflects oil away from the PCV, so there's no oil transfer. The engine had a full compliment of oil -- it was not low. And the "noise" you hear was from the high-pressure fuel pump. A noise that's considered normal by General Motors. It was confirmed using A stethoscope.

Thanks for posting. I serviced mine today (2013 Equinox 2.4L). Orifice hole was completely blocked. Engine was not consuming oil - I guess I am lucky. I did not add the PCV upgrade, but followed the GM service bulletin - cleaned orifice and drilled a slightly larger hole. I did not need to remove secondary fuel pump - just the fuel line and metal bracket. I managed to remove manifold down and past the protruding fuel pipe on the pump. Put back together and have vacuum again. Also, my electrical connectors came off pretty easy - none broke fortunately. Will check vacuum on subsequent oil changes to see if hole gets plugged again.

Secondly, in addition to relieving pressure it's also designed to remove harmful fuel vapors. The only safe way to remove the fuel vapors is to burn them in the combustion chamber.

The breather tube to the air plenum could be clogged, so remove it, then blow air pressure through it to clean out any clogs. If you still have white smoke, add some Lucas oil additive. It should help to seal the rings better -- if only temporarily -- but it will help to diagnose the problem.

How big is the PCV valve are you using, you don’t say. Valves and the flow rates are built into the air/ fuel calculation designed by the engineers. Messing with will bring on the Check engine light. Before you just start drilling holes in your intake you should find out how the engine works and the consequences of making shade tree modifications are.

The fitting is placed at the bottom of the runner, so it doesn't affect vacuum signal to the cylinder. There is no check engine light that's been illuminated. Not when it was installed, and none to this day. I haven't had any "lean" conditions on any one cylinder associated with this modification. Your fears are unfounded. If you want to research the PCV dimensions, etc., the part number is listed so research away. The only thing that's changed is that I no longer use any oil. The level remains at the full level, and I have changed the oil more than a few times. I sample my oil, and the oil is more stable now, maintaining adequate viscosity.

You are correct. This hack will work but just buying time. The original design is a good concept but the way they did the design is terrible.

well i did your fix and so far it is not working. burns as much oil as before and i even put in new rings. my next step will be a new engine. but i will give it a month to allow the rings to seat just in case they are causing this. i will let you know. thanks for the possible fix it may work for others

Did you change your oil after doing the modification? I took my Equinox on a long trip on the highway. I also test my oil to see what's going on inside my engine. I found fuel dilution in the oil that I am still chasing. One theory is that the high-pressure fuel pump is leaking down after the engine is Off. Another theory is that the injectors are not shutting down with the engine Off. Difficult to diagnose, but could contribute to oil consumption from washing the rings.

@@Frank4358 , frank i overhauled the engine. new rings head and rod bearings. and of course new oil. 30w breaking oil. no difference at this time. also did you know you can't block off the original pvc vent? i installed a tapered screw kind of like a idle jet screw on the carbs and when i had that factory pvc blocked off i had more outbound pressure on that port that goes to the breather than with it open. so i had to open the about 1 1/2 turns and that port got to 15" vacuum and i took off the gage. at the same time the mod pvc i put my finger on the suction side and it had plenty of vacuum i did not bother to check it because you could tell it was sucking plenty .but as i said in the top comment the rings may not have yet seated. so i'm giving the rings a month or so and 1000 miles to seat. thanks

frank i think i now have a lean condition with this upgrade? ever since doing this she now has the engine at stops want to stall out at stops. what i'm going to do is take the pvc and clamp off the hose and let her see if that changed the stalling issue. if it did then i will open the clamp a bit at a time until the stalling stops and then it may be fine. your idea sounds good but if you do not have the lea engine then we have 2 different systems. she has no egr nor a iac module. so that may be the difference. thanks

I will tell you this; Since this modification was done, I have not used any oil, at all. There were no check engine lights, and the fuel mileage was unaffected. The clacking noise you hear is emminating from the high-pressure fuel pump. Cold start/fast idle and IAC operation is working normally. Warm idle is about 700 - 750 rpm, and the engine operates at about 1500rpm at 45 - 55 mph. One more thing; I changed the transmission fluid with Amsoil synthetic. Transmission seems to shift smoother, and around town/highway fuel mileage increased from 16mpg city/22mpg highway, to 19 - 21mpg city/25 - 27mpg highway.

Emissions control systems are closed systems. That's so any vapors from inside the engine are harmlessly burned in the combustion chamber. If you vent these vapors to the atmosphere, you fail emissions standards. I'm not sure how GM gets away with this. And if this is an option, why doesn't GM dealers know about this cap?

To vent to the atmosphere is a violation of emissions standards. PCV systems are designed to redirect the atomized particulates back to the combustion chamber to be burned off. So no, putting a filter to release into the atmosphere is not a good idea.

@Frank4358

4 жыл бұрын

A breather does not do what a PCV does. There is a breather return from the cylinder head to the airbox. The PCV evacuates crankcase pressure, but it also carries any hydrocarbons that are within the mix. Those hydrocarbons are sent back into the intake where it is mixed with the air and fuel being pulled into the combustion chamber to be re-burned. It's part of the emissions control system. By adding a sealed PCV (not vented to the atmosphere) you don't bypass the vehicles emissions system, and you pass state and federal emissions standards.
