Unhappy HELP!!! PCV VALVE POPPING OUT!!!

Ok, got the blower on. Now I have a bigger problem. My PCV valve in the back of the motor keeps popping out and gushing oil out after acceleration. What is causing this?

Is it because my by-pass vaccum line tees into the FMU vaccum that goes into the back of my intake??

PLEASE HELP!!!!!

Have you done a leakdown test lately? Sounds like some wicked blow-by.

But I am not burning any oil. It has good oil pressure, and it runs strong.

Is there anything else it could be.

That might very well have something to do with it.

Just found this out. Even though I lost so much oil, it still shows full on the dip stick. Could too much oil cause this problem?

You might have a venting problem. I had a similar crankcase pressure problem. When I built my 347 I had so much pressure I was blowing out the seal at the back of my intake manifold, even though I had an open breather on each valve cover. I had to setup a good suckin pcv system to vent the crankcase
Just something to consider, hope it helps.

Dustin, do you still have that tube that connects from the valve cover to the throttle body connected?
