| RE: Oil Blow-By |

I have the same problem with my 428 in my ERA Cobra. My breather is out the back of the intake manifold. I got some relief from this problem by teeing two hoses from the both valve cover caps to a PCV valve. The goop that comes out however is a yellow/gray goop that is primarily oil additives and water. Now think of that...water...not from the cooling system, but from condensation mostly and the combustion processs to some extent. Condensation you ask?...well it is a car you don't drive every day, or very far. So this is what happens. You drive it fro a bit...not long enough for the PCV system to suck all the moisture into the intake and have it burnt...then you park it in a concret garage. As the engine cools down...the air inside contracts and draws cool DAMP air inside from the garage. Next time you start her up...the water mixes with the churning oil, and hangs up with the additives. Even a brand new engine has blow-by,...so when the blow-by exceeds what the pcv system can suck up...it comes out the breather. Yup...I got it too...and can't seem to resolve it 100%...Oh well...the car's fun to drive anyway...Oh, and did you notice the problem is worse just after you change the oil...it's all those additives coming out.
Best of luck
