That looks more like ring sealing issues than valve seals to me. Have you checked the compression? Sounds like it needs some P/S fluid too. :-)

Power steering looks good. I don't know why it's making that noise. I'll check that tomorrow in the daylight. I hope it's not rings that would suck... Might as well do the stem seals before I do the rings though because if the stem seals are the problem it's a lot less work.. this motor has ~100k on it FYI. I'll do a compression test sometime soon.

Oil has been changed very recently. Rings again I'm hoping that it's not that.. but I will do the compression test. How do I test the ventilation system?

OH BY THE WAY: MY CAT IS BURNT UP. so I'm just putting that out there.

Re: Smoke the camaro...

i was sayin crankcase vent, only because after i replaced the crankcase vent, it stopped smoking (it smoked just a little bit before) I seen a post somewhere... and since the crankcase now had a good suction it helped keep the rings tighter to the cylinder not sure how it works

a cp test would help, HOPEFULLY its only one piston
