    crankcase pressure

    I have oil being pushed out of my valve cover breathers at boost and was wondering what any of you have to stop this.I bought a crankcase evac kit(the one that welds into your exhaust) but a friend of mine has it too and he now has smoke coming out of his tailpipes b/c of the oil entering the exhaust.Does anyone have a smog pump hooked up to fix this problem,if so can you post some pics for me.Thanks...Matt

    One thing to try if you haven't already is a PCV valve from a Thunderbird Turbo Coupe...you can only get it at your Ford dealer under part #E5ZZ-6A666-A. It has a rubber covered orifice, and is designed to contain boost unlike the stock Mustang piece which lets boost go right by and will pressurize the crankcase which will lead to your problem.

    You can also add a check valve inline between the intake and PCV.

    About $20 from Bowling Green Customs.
