remember the old valve cover cap with steel wool to catch the oil/ vapors. looks to me like ring blowby is worn cyclinder/ rings! it would be interesting to see the cyclinder temps to find out where the oil is burning off, as in why the engine puts out oil smoke at tailpipe. old timers used to say black tailpipe bad, i think, on the gas burners.
The rings and cylinders aren't worn any more than usual, this is just common on 6.4's, especially when they're modded like mine (it can hit 40psi of boost which the ring seal doesn't seem to be up to the task for). It doesn't burn any oil at all, it just pressurizes the crankcase more than it should, which in the factory CCV system reroutes vapours back into the intake system and over time coating sensors in sludge
I remember building a few 6.4’s several years ago and they all had a ridiculously large ring gap from the factory. Guessing it’s navistar’s idea because of the higher boost of the compounds🤷🏻♂️. Anyways, no matter how I spaced the rings they all had blowby after they were put together. But on one build I used delipped maxxforce pistons with a tighter ring gap and it had zero blowby.
idk abt these but the 6.0s are designed to suck the oil back thru the turbo and burn it off putting a catch cab on a 6.0 is a death wish for you’re turbo and i’m assuming goes for the 6.4s also
No truck is designed to suck oil through the turbo. All turbos are lubricated via dedicated oil feeds from the engines oiling system, plumbed through the center sections where the bearings are. If you're talking about the crankcase ventilation system, every vehicle since the early 70's has had some form of it, and it's supposed to send vapours through the intake system not oil. If your rig is sending oil through the turbos you have a problem, one that the catch can helps to alleviate.
@@backwoodsbuildingandfixing9223 every diesel sends small amounts of oil thru the crank case ventilation don’t know what your talking abt😂 your gonna get oil thru there no matter what catch cans on them is stupid and useless
@@backwoodsbuildingandfixing9223it’s not rocket science i’m not sure abt 6.4 i’m sure it’s abt the same the turbo does create a small vacuum on it and it helps relieve crank case pressure venting to atmosphere actually holds it in and increases it and they do suck oil thru it’s diesel your gonna get that it just happens and they do burn it
Jesus bud. You're right, it isn't rocket science, but it's clearly still over your head. There is no more vacuum on the CCV tube than there is on your air filter, which is virtually none, if you think that is going to suck oil up from the crankcase into the rocker cover and into the intake you're in fantasy land. I've been messing with every version of internal combustion for 30 years and every kind of crankcase ventilation system on them, the one thing they all have in common is some attempt at keeping oil out of the vent tube. Whether it's a simple splash shield in the valve cover, or a mesh filter canister, or a fancy vortex inducer like in the 6.4, EVERY SINGLE ONE has some method designed by an engineer to prevent oil from getting into the intake. There is only one way oil gets past these measures, and that's excessive crankcase pressure. And the only reason for excessive crankcase pressure is excessive blowby. Only the hackest of hillbilly mechanics will ever try say that excessive blowby is just part of how an engine is supposed to work. By the way, if you paid any attention at all to this video or the other videos I've made on the subject, you'd know that I went from pouring oil out of the intercooler to having a dry intake, and plenty of oil in the catch can. You need to tuck your ego away and do some learning, because you are nowhere near knowledgeable enough to tell other folks they don't know what they're talking about.

@@backwoodsbuildingandfixing9223 they do suck oil thru how else would u explain oil in the inner cooler smart one🤣
so mishimoto works i guess but yes expensive !
It does seem to be working, I'll be dropping the plug in the can soon to find out for sure though
I bought it under protest because my intercooler boots pop off…..
