After an engine rebuild I have been troubleshooting an oil consumption problem for a few months now with no results.

My symptons:
burning oil, anywhere from a quarter of a qt to a 1/2 for about a 30 minute drive
white puff of smoke when I left off the accelerator
oil is constantly in my IC piping, throttle body and intake.
I'm getting oil all the way to the MAF

What makes me suspect this is that I constantly have oil in my IC piping, inlet and intake.

 

Sounds like blown seals on the turbo to me.

+1 on what Skyline says above,

 

Blown turbo, I had the same problem.

 

Im guessing its blow by oil. whats your catch can setup like? It is unlikely its the turbo unless the center housing is going under pressure, which would also be from piston rings. You said you just rebuilt the engine..were new rings used with a fresh hone? Id compression test it to start with.

 

Im not sure how much you have played with turbos before but this is supper unlikely. The turbine seal is like a piston ring and trapped in the center housing by the turbine wheel. Unless the bearings are wasted chances are the seal is fine.

 

I don't think you know what your talking about.

 

If he is filling up pipes and the FMIC with that much oil than it is definitely much more than blow by oil. You could be running boost to the high heavens and not fill up with that much oil. Am I just over exaggerating on how much oil there actually is, or is there really a good bit of it, OP? Do you even have a catch can set up? If you do and there is still this much oil then I am going to have to go with skyline. Somehow, wether it be the seals in the turbo etc, oil is making its way into the charging system through the turbine housing. You need to pull the turbo, check for shaft play and remove the compressor cover, see what you see. Take pictures if you want some more input.

 

First, check for excessive axial turbo shaft play. If indeed there is excessive play, then since you are located in Texas, it is a no-brainer. Ship your turbo to Forced Performance and have the shaft seals replaced.

 

I'm using an oil catch can. Went with AMS engine rebuild kit, so new rings. Also did the counterbalance shaft delete.

It's possible the center housing of the turbo is getting pressurized.

So, I didn't have this problem until after the rebuild. I bought another used stock turbo and the problem persists.

I don't think it's the turbo.

 

Actually, he does! This is exactly what the guys at FP told me.

 

White smoke is evidence of burning fluids like antifreeze. Is is possible that your head gasket is bad causing oil and antifreeze to migrate.

If it were the turbo seals you would be noticing blue smoke from the exhaust.

This sounds like a serious issue and I would definitely get it to an Evo shop to diagnose the issue.

 

Naw. If, when glancing in your rearview immediately after throttle let off while accelerating under boost and observing white smoke.... it is not the Little Big Horn Pow-Wow. It is blown turbo seals.

 

How much oil are we talking in the pipes?

Blue smoke indicates that oil is being burned in the engine. White, in addition to what you posted, could be an oil leak post engine.

While it is unlikely that the bearings are good but the rings are bad, I still wouldn't rule out the turbo. Drop the downpipe and see if there is oil in the neck.

My initial suspicion is the engines oil rings or valve guides if the engine compression turns out fine.
