Good luck, hopefully my error helps you out. How many miles on your car? I suspect this is a high mile thing.

Thanks for the feedback! My Z is a 1990 with 7700 miles on it, which is not that much. But if I go highway 15 miles it drinks a quart of oil. I have read some of the posts regarding exhaust seal, which I lack and maybe that is a reason. There does not seem to be any blue smoke but if I hold a paper towel behind the exhaust and someone gives is some gas the towel becomes very black...
I have just changed the PVC lines (to Jerry's) in case that is related to the issue. The previous owner had done a strange connection from the top of the PCV valves and the bottom line had been pinched somewhat. Havent driven the Z since the update but it feels like there is a bigger issue.
I have not noticed any noticable oil leak either until just recently. Something I am looking into as well.
Sorry for the long post! Ill need till check the plugs as you suggested.
