My oil pressure gauge is still showing 30 at idle and gets up to about 50 while driving. The pcv rattles like its about to blow, this with the breather in. The pcv is new and the tubing is good. I'm assuming that the blow-by is causing the pcv rattle. Any ideas?

The pcv valve is supposed to rattle. It opens and closes rapidly and makes a ticking sound. If it doesn't rattle then it's either plugged up or otherwise not functioning, or there is no vacuum supplied to it. As far as your oil pressure those numbers are not anything that would give me concern. If you want to verify that your gauge is giving you an accurate reading, hook up a mechanical diagnostic pressure gauge to the inlet at either the oil pressure switch (above the filter) or at the oil pressure sending unit inlet (behind the distributor).

Okay, thanks Grim. So, they designed that pcv to make such a racket? I mean, its loud. Loudest thing under the hood for me.

I'll feel okay about things until I can get a pressure gauge and really see whats going on.
