Definitely do a compression check to determine what your issue is. ASS U ME anything is a fools game and can cost a lot of waisted dollars.


A couple of items:
- Simple first, pull the pcv valve and check that you have good suction to the carb.
-Do you have an aggressive cam? ie reduced manifold vacuum.

-Do a complete compression check to determine the status of your engine.
- if it is a ring issue, a) start saving money for a new engine
- you can try using thicker oil (ie 50W), but it won't help a lot on a long drive.
- you can vent into a catch device instead of your carb to reduce smoking etc and drain it back into your pan. Kind of a pain, but if you a blowing a ton of oil it works. I would only do this if you are fouling plugs every couple of weeks.

PS> I think GM uses a Positive Crankcase Ventilation system, not sure what a PVC is :-)
