Hey guys, I need a little input to see if my thinking is correct.
I just picked up an '87 Shelby Z. The last owner put many mods on it, and sold it when he thought he blew the turbo and didn't want the project anymore. Lucky me the turbo is fine, but it is still blowing oil out all over.
I found the oil is coming from dip stick and the PCV. Well, the last owner put an open air filter and tube to the turbo, and instead of tying the PCV back into it, put a breather on it and put it over the transmission.
My reasoning: The PCV has a vacuum on it from the intake manifold. BUT when the turbo is boosting the intake manifold is blowing air back into the PCV, instead of sucking. The sucking should then come from the intake right? And since they are no longer tied together the boost in the intake manifold is blowing oil out the breather. AND since it looses it's vacuum the crankcase builds pressure and blows the dip stick.
SO, if I make a nipple for the intake tube it will replace the vacuum that was once on the PCV.
I need to make sure this is correct before I make the nipple and have the thing blow oil into the turbo.
Thanks guys!!
