Help me diagnose oil burning after cam.
My Trans Am is definately burning oil. I did a cam swap beginning of last season and i didnt really notice it till track day and now its fairly regular. Steady small amount at any rpm.
I want to know all the possibilities that could be causing it and what would be the course of action to diagnose the problem. I want to put on nitrous in the spring but I would like to fix this first. I have no loss in power and the engine seems to be running great. I trapped 116s regularly at the end of the season.
Possibilities I think:
Bad Oil
Bad Valve seal
Piston Rings are shot
Bent Valve
What i plan to do in the spring, let me know if im taking the right action:
1.) Change oil (I dont remember what kinds in it but its documented on another computer)
2.) Change spark plugs and look for irregularities on any cylinder (changing to tr-6's for nitrous.)
3.) compression test
4.) Pull valve covers

A compression test is good, but a leak down test is even better. I think the usual culprits are rings, valve seals, and valve guides. If you're valve was bent, I think you'd know it - you wouldn't be making good power or run well. You can lose a little through the pcv, but that's normal. How much oil are we talking anyways? Like you go to the track, come home, and it's half a quart low or what?

its also not a start-up symptom either. I cruise with him all the time and it will have a very slow, small, steady draft of blue smoke out the tail-pipe. It will make a bigger puff after he gets on the throttle and lets off at a high rpm.
The car runs great, its def healthy so im betting its the PCV system.
i do know a guy that fried his rings in 30k miles, but he drove his car like he was GM torture tester.
