Been messing with things all week. Don't know if it's just an issue with my car or if I've actually proven something. I spent all week trying to find the vehicle application for the 1162 pcv valve. Finally figured it out and purchased one through a local parts store. They had one in stock and could not get any more. Put the 1162 in and didn't notice much of a change. Decided to install a cheap catch can to see if it would help with the pcv sucking oil, it did drastically. One thing I noticed once the car was up to temp at idle, the driver side valve cover breather was still puffing some smoke?????
Decided to pull the 1162 valve and install the original gm one. Blew through both of them and noticed the original flows a lot more air to the intake side. Started the car and let it idle for a bit, no more smoke out the driver side breather. My finding is the 1162 wasn't pulling enough vacuum from the crankcase to relive the pressure. Took the car out for about 20 minutes and did 5 boost pulls (23psi) and cruised around town for a bit. Came back home and had about a 1/8 inch of oil in the small harbor freight separator I installed. Still no smoke from the breather and much less smoke on start up. I don't have a check valve installed between tb and the catch can yet, but it's good up to 150psi so it shouldn't be too big of a problem.
