Thought I'd mention that different engine manufactures run this test differently, i.e. idle no load to high idle no load. Just so the viewer knows but depending on engine manufacture you can have other causes of high blowby. Such as a bad air-compressor. A leaking intake manifold/valve cover gasket bad oil seperator. It's getting to the point now a days that the rule of thumb is getting thrown out the window. Love your videos keep them coming. :)

I have been driving tractor trailers and am now in real estate. I enjoy driving trucks but real estate not so much. I have missed the diesel field for quite some time but seems difficult to get hired today without certifications. I have tried for Peterbilt, Cummins, and Detroit Diesel since we don't really have a Cat Truck shop anymore since they phased out. The only Cat shop we have now is more for heavy equipment and I don't really care to work on the machines, prefer trucking. Seems like the ones getting hired have technical school and certifications but little experience. My old Cat job was old school and basically just trained on the job so I left without much to show and now I have been out of it for some time. They have since closed shop since the Cat truck engine market kind of died of. Thanks for the reply

Good morning Josh! Came back to this video as we have a truck in the shop that had combustion gasses in the cooling system and it received a long block (PACCAR MX-13). The truck now has blow by both out of the oil fill tube and the crankcase tube. For transparency the technician that did the install was inexperienced and did not replace the oil cooler or flush the oil module (Claims there was no metal) and they used about a half a can of ether over the course of an afternoon as they could not get the truck to start initially (Bad High Pressure Pumps). CCV filter has been replaced. He was told to drop the pan and inspect the liners from the underside. He found a small vertical mark on cylinder 2 and orders from above were to replace the liner and rings on said cylinder. He stated to me he couldn’t really feel it with his fingernail. I don’t believe it will solve the issue. After his repairs I’m looking to come up with a strategy to isolate the source of the blow by. This is what I have come up with: Bring truck up to operating temperature. Verify blow by. Disconnect air compressor inlet and outlet to isolate air compressor. Run unit and revaluate. Pull rocker shafts off to ensure closed valves. Remove turbo feed and drain tubes from block. Pressurize turbo inlet to check turbo and intake valve seal integrity. Revaluate unit. With the rocker shafts out pull all 6 injectors and perform a cylinder leak down test on each cylinder. Wanted to see if you have any input? I can email you a video of the blow by and the mark the technician had found. It was his first major engine job and I’m preparing to take over his work.

@edwardreyes6867

Also metallic glitter was found in the oil pan once he dropped it to inspect the liner bores!

A turbo may cause crankcase pressure but by definition is not blow by. Blow by is literally gases blown by the rings in a cylinder.

Remind me of a truck at work, had blowby as bad as the RV and burned 8 gallons of oil a day. They used it that way for about 10 months

I know nothing about engines but removed my oil filler cap on my diesel and it was puffing air out like a steam train. No smoke or colour, just air and oil.

So accurate. I always said when a Cat engine idles and it has that sweet oil smell it's going to blow up real soon. Also I don't know why some Cat liners have a real noticable taper after many hours verses a Cummins..Maybe because Cat depends on Two compression rings as other manufacturers use more rings for this purpose.

I don't believe it is legal with the EPA and since your truck is a 2007 or newer, a knowledgeable DOT inspector may notice that your engine isn't an emissions engine. Now depending on what area you are in they may not notice, but if you got caught it could be some big fines. I understand wanting to put a more reliable and powerful engine in your truck, but I would hate to mislead you. If you know someone that has done it in your area maybe you can discuss it with them, but as far as I know, it is risky. I'm glad you like my videos, In going to be doing a regen class soon as well so if you want to know more about your emissions maybe check it out when it comes out.

I’m interested in that tool to measure flow out the blow by tube. I currently use a manometer and that is a lot less hassle.

Great videos sir. Thanks for all the masterful knowledge. I have an '07 W900 with a C-15. Last week it blew the oil fill cap off & pushed out 4 gallons of oil while pulling a load. I replaced the cap & oil and within 10 miles it did it again. We put a pressure gauge on the filler neck & without a load were only able to generate 1-2lbs pressure. A compression test indicated all cylinders are sealing within spec - they should be as this engine has 17,000 miles on it since a complete in-frame. The thought is that the high-pressure turbo has lost its oil seal & is pressuring the crank case. Before the expense of replacement is there anything you would suggest we look for? Thanks again, my son & I really appreciate your vid's.

If you already have cylinder damage or a broken ring, then you can unplug the electrical connector to that injector to prevent the injector firing into a dead hole. You should be able to run it home without a problem, obviously you'll have a lot less power. These engines don't have liners though, you probably knew that, so you'll have to get a new sleeves machined in or get a new short block. Let me know if you have any other questions, and subscribe please.

Ogre Under Bridge White- oil burning through turbo exhaust, turbo, cylinder ware, valve seal, or blow by. White smoke at start up after a duration of time(sitting over night) means a injector is leaking.

I'm seeing oil leaking from the intake hose seals next to the turbo and also from the oil cap. Compression test was done on this engine a few years ago and it was perfect, also I don't see any smoke from the exhaust or loss of power. Is it likely that turbo seals are the problem ? I looked at PCV valve too and at least some air is escaping from it when idling, so it's not fully clogged or something.

My Detroit 60 series has much much greater crankcase pressure at idle than under full load. I've tested it with a manometer. Truck runs great does not use excessive oil. Why would this be? It's smoking me out at idle but no other issues.

@AdeptApe

7 жыл бұрын

Well I'm no Cadillac expert, but I'll give you my free opinion (you get what you pay for). An engine oil leak doesn't have anything to do with the transmission cooler, as they are separate systems. The PCV system should keep the blowby under control by allowing the intake to ingest the blowby and oil fumes. So if you are getting an oil leak you probably have a problem with your PCV system that fixing should stop the leak. Now a catch can would stop the leak from getting on your driveway, but the engine would still have PCV problem. Sounds like what your mechanic said makes sense.

It's official an in frame and turbos. I'm like Johnny Cash I got it one piece at a time but it cost me every dime. I think these shops know exactly how much money I have.

Hello , I was looking for a video where you talk about a truck with a new rebuild had a blow by for idle too much

What of engine breather is bringing out oil

great video. I always ran leak down tests if i suspected high blow by to help isolate the problem, but this is a cool way as well. How would i know how many times to multiply (1.5-2) for any given engine? Does CAT or most major engine manufacturers have specific values for this blow by test?

@AdeptApe

8 жыл бұрын

Hey Regal, so the 1.5-2x is the Cat spec on their truck size diesel engines. They vary depending on serial number. A C7 may be 1.75x or a twin turbo C15 might be 2X, but a good rule of thumb is 2X. The problem with leakdown tests is they are hard to do in a diesel setup. The automotive ones are great since you just pull a spark plug and your ready to go, but that could take hours to set up on say a 3406 then you have to reseal all the injectors. Our shop doesn't even have a compression or leakdown test kit. You can try doing a cutout test and watching the blowby to isolate a bad cylinder, that works at times if you have a single bad cylinder. Now when it comes to all engines, gas and diesel, I'm not sure what a good specification would be since a non boosted engine should have significantly less blowby normally, probably 1x horsepower would be my guess or maybe 1.5x for high compression. Thanks for the comment.
