    Oil infront of throttle blade!

    So i took of the charge pipe off to install my methanol injection nozzle and i see oil before the throttle blade.
    Im at 37,000 Miles. 1000 Miles until my warranty is up.
    I've been keeping track of oil consumption, last time i measured 4 Liters going in, so when i saw this i replaced the oil and messured what came out. Exactly 4 liters. No smoke coming out the exhaust....

    How screwed am I? I can't imagine this being normal. But this is also my first turbo vehicle...

    Depends, it could be excess from the PCV (blow back, pressurizing the valve cover, etc). Do you have oil in the IC?

    I am fighting the same issue with the SRT-4 right now. It's forcing air through the PCV while under boost which is causing oil to spew out the vent and into the cold side pipe before the turbo (which is causing so many other problems).

    It will be alot of work to get to my Intercooler, what other problems is it causing?


    I took a look on other forums and they say oil post turbo is normal, especially if your PCV running back into your intake.

    So i guess its normal, thats 38,000 miles of oil build up, and i have no measurable amount of oil consumption.

    Still would like a second opinion.

    I don't believe the Cruze has a feedback from the exhaust in to the turbo intake like some cars. That looks like condensation and dirt to me. If it was oil you would have to be burning the oil through your engine, then feeding it through the exhaust, squeezing the oil through the turbo impeller seals, and back to the intake at which point it would be re-burned a second time (and would no longer be in an oil like form due to combustion). Plus there would be other signs such as blue smoke and lowered oil level.

    My guess is it is either condensation and dirt, or slight oil from the turbo seals/oil, or a little bit of both. Nothing to be worried about.

    Pull the PCV line and check for oil to make sure thats the cause. If it is then I recommend a catch can and a check valve.

    I literally just got this in the mail. It's the check valve that I'm putting on the SRT-4 to fix that issue.

    You might not have a lot of consumption but it could start blowing out of the tubes and causing a bad smell (or fire). But you certainly don't want it getting into your cylinders. But we need to figure out where it's coming from.

    What does it look like inside the TB? Same issue? Does the blade have a residue on it?

    You're thinking of the EGR.

    The Cruze doesn't really use a PCV system that's entirely effective at removing oil blown past the turbo seals, so there will be some oil in the charge pipes.

    A catch can/separator box will prevent this, if you're so inclined to rig one up.

    One of the coolest designs I've seen was a built-in catch can on a car that separated oil vapors, condensed them back into oil, and put it back in the oil pan. But unfortunately, it clogged up usually within 5 years and required massive disassembly to replace or clean the system.

    ^Repair procedure, if you care to look at it.
