ok, did my 42lb injector swap and ran across........

[Instigator]

oil in my intake manifold.:disgust:

now, there might be several reasons for the small pool i saw run its way along the wall of the TB inlet as i rotated it around.

1.) turbo seals
2.) bad pcv valve
3.) bad rings/hole in piston

#1 is not the problem. i pulled ther turbo and there is no oil anywhere on the compressor side nor in/on the turbine. Turbo is fine.

#2 i have no clue. this is the pcv valve that came with my escape engine. maybe its bad and is constantly open and flowing oil into the engine.

#3 i hope its not this, i mean, i'm pretty sure its not, because a.) my psitons are forged and probably the strongest out there and 2.) this car hasn't seen more than 75% throttle or higher than 4K rpm. since its induction 1100 miles ago.

when i say oil, i dont mean a flooding of it, just enough where if i pick the manifold up and roll it around it flows in little streaks acros the interior walls. none actually flows out of the holes when i hold it vertically. just enough to make me uncomfortable. when idling and revs it doesnt really smoke hardly, you can see exhaust fumes but they dont look to be signs of something bad.

maybe im just paranoid. i did read over on CEG about the Lightning pcv valve being better and usable?

thanks

do you have an oil / air separator?

those work awesome :bowdown:

PM me if you want a good price on one.

Is there oil in the outlet tube of the turbo leading to the TB? If so, check your valve cover breathers first as these like to puke a bit of oil on the forced induction cars. If that's the case, install a air/oil separator in line before routing them to the inlet tube. If there isn't oil in the outlet tube, then check the PCV valve setup as that's the next most likely cause. The piston hole theory doesn't necessarily fly as you'd have to force it clear back up into the intake manifold against all the air rushing down and if it were bad enough to coat the inside of the manifold, you'd see the problem manifesting itself in other ways. My bet is on the valve covers pulling oil into the intake tract as I fought that problem for quite a while.

Depends mostly on blowby past the rings and how you have your PCV system done.
And no, the lightning PCV isn't really better than stock. THe stock one has the correct sized weight in it for a 3L/2.5L engine and the amount of airflow it is designed to draw in at idle. The lightning pcv is for a big V8, so think on that. We are talking idle, not under boost.

Second, not all stock PCVs seal the same. Buy a new one and check it by trying to blow through it. It should seal pretty good with only a tad of leakage to no leakage. If it has a lot of leakage then get it exchanged for one. Autozone will let you check all kinds of them till you get a good one if necessary.

Second, the valve cover vents should be plumbed into the intake before the turbo so you aren't pressurizing them. This ensures that you allow a pathway for the crankcase pressure to escape under boost. If they are after the compressor then there is your problem.

If you still have excessive oil being pushed out the valve covers then use the oil separator. If you are pulling a lot in through the PCV system then you could have the wrong sized or a bad PCV, or you have a LOT of blowby past the rings even at idle. Thats it really.

i have my valve cover vents going into the intake stream BEFORE the turbo. i really need to get an air/oil seperator.

i got the steeda one from spm but u can always use the one that sears sells
