I have 01 ws6 and it burns oil and smokes when I get on it.The smoke color is like a blueish and it only has 54k miles. Im getting a cam (Torquer v2) but I don't wana hurt my motor if there is something wrong with it already. I was woundering if anyone can help me out and tell me whats wrong with my car and if its safe to go ahead and put the cam in it. Any help would be good , Thanks.

that 160* thermostat could be the possible guilty party. Its not allowing te engine to reach proper operating temps. Thus allowing oil to slip. I had a 185 and dynoed 13 hp less with it vs the factory, plus ran rich and smoked like a train. A friend has a 408 that runs in the 9's with a 160 and it was losing 22rwhp over stock.

I would bring the car to a tuner and check the AF as well as have him look around for any codes or **** like that

I was told it could be a bad PCV valve, what do u guys think?

I would think that if it was a considerable amount.. that the rings would be going bad.. your miles are low.. are you the 1st owner?... what mods are done? whats been serviced or changed?

Our ls's are built with very specific clearances between moving parts like bearings and in this discussion piston to wall clearance. Although the rings have tension against the cylinder wall ( which is how they seal up the area between the piston and wall) the piston itself must have a few thousandths of an inch clearance between it and the wall or it will lock up. when the engine is cold those clearances are bigger than when hot and will allow more oil to creep up into the chambers. some has to be allowed in for lubing but when too much gets into the chambers it can cause detonation and blow smoke. also if your engine is not allowed to warm up the rings are a little looser than they should be inside their respective grooves and cannot seat properly against the wall and the piston grooves. gm engineers calculated and tested the materials used in our engines and came up with thermal expansion values and the effiency of our engines depends on how close we let our engines warm up to those values.

If you are blowing blue smoke on acceleration you're rings are probably worn, you can try checking A/F ratio and blocking off the PCV to make sure but more often than not it's rings.

If you are smoking on deceleration it's usually guides, PCV, or rocker bolts.
