Just in case anyone else is wrestling with the same problem I was having, the factory shaped hose coming off the top of the PCV valve is coupled together with a straight hose that leads along the valve cover towards the firewall. Inside that coupling is a pinhole baffle that on older engines becomes clogged with crap in the oil. All I did was clean this unit with brake clean and open the hole up a bit with a drill and I haven't had a problem since.

If you're having this problem give it a try. (it's a FREE FIX)
