Is your pressure relief valve opening at a normal oil pressure? If your pressure is super high, you could have excessive oil delivered to the rockers, which could cause the problem you are having. Another possibility is broken rings on one or two pistons, or all the end gaps aligned with each other instead of staggered. Lastly, if you are using dirt-cheap motor oil, it can foam at high RPM and blow out the breather.


I suppose it is possible that the oil pump pressure relief valve could somehow get clogged and cause oil pressure to increase but NO, mine is fine. Oil pressure has never risen over 60-65ish and thats when cold or warmed and in throttle. Otherwise idling warm its 35-40ish

Okay now let's spend a couple of weeks discussing what happens if you tie buttered toast to a cats back and drop it.


This forum has a way of getting caught up on some of the smallest details

IMHO I think it depends on how thick the bread is and how old the cat is. It doesn't make sense that a young cat would have knowledge and skill to turn over if it had too big of slice of bread tied to it.If I know someone's going to argue it doesn't matter how thick the toast is.

Are we talking an African cat or a European cat?

Because it doesn't frikin matter! It's like a tornado in there, the inlet and outlet could give a **** which side of the block their on. It's simply a matter of convenience. That's my opinion.

I guess no one told you.We are now arguing about buttered toast and cats.

What happens when you use cat skin cut in the shape of a V to test the PCV?

Depends if it is short hair or long hair. Long hair will better define the crankcase airflow characteristics.

But, I'm in the "doesn't matter which side" boat. As long as you have a PCV, the side you use will be determined by packaging.
