pcv

The separators may do the trick for you.

Also, I didn't mention the pcv screen that goes under the pcv. This is quite often left out when upgrading manifolds and engine rebuilds.

At about $20, the separators are worth trying.

To make sure that you don't have any major problems causing the higher crankcase pressure, it would be nice to do a compression check on all 8 cyl. I have been told that sometimes a ring or 2 just won't seat. I can't say how common this is though.

What do you know about the rings that were used in your engine? If they were low tension rings, that would def. cause this problem.
