    Oil out of valve cover oil cap under boost, did a compression test......

    I wanted to see if my rings were bad so I did a compression test tonight on the car and it was as follows:

    Cylinder #1: 145
    Cylinder #2: 140
    Cylinder #3: 135
    Cylinder #4: 145

    The compression test was done with the engine cold so I know the rings are in good shape. I've got a vented catch can hooked to the breather on the back of the valve cover but I still have issues with the oil coming out of the oil fill cap and this is only with 7-10lbs of boost. Any ideas on what I can do to get rid of this? I'm afraid to turn the boost up for the sake of blowing out tons more oil. At idle there is NO smoke coming out of the dipstick tube at all either cold or warm.

    I know they are Hastings rings but do not remember the gaps used off of the top of my head.

    Heyprick,

    You blowing me off? Where's my turbine housing? Whats that UPS tracking number? DID YOU EVEN SHIP IT? Blow me off one more time, and you'll wish you never decided to screw me. All it takes is a phone call to the BERRIEN COUNTY SHERRIFF at (269) 983-7141 and that will be it. I see you have time to for posts on here, but don't you DARE blow me off. I swear I'll spray all the information about this BAD DEAL on here. Just blow me off ONE MORE TIME. ONE MORE TIME!

    Bad pcv valve? That can cause boost pressure to get under the vc and push oil out the cap
