There seems to be no power loss and it just burns some oil just wanted some feed back!!!! PLEASE help im concerned by the way the car has no egr valve smoke happens at high rpm

More than likely your piston rings are toast.. Start saving for a new motor.. Do not feel bad I am in the same boat...

How much smoke? Like a train, or just a puff at WOT? If its a puff dont worry about it, more than likley its carbon build up. If its like a train, its your rings.

The cats have alot to do with it. With just a light puff from a wot or at start up normaly the cats would catch that. it being carbon, or blow by sucked through the intake at wot.

Anytime the cats are out thats what you have to deal with.

Blue smoke is oil. Could be several things. Do a cylinder leak down test to pinpoint the problem.

correct me if i am worng but you should look at that as a good thing means you dont Beat your car carbon build up. as stated above. when at my friends wook haning out i see lots of C5 Vettes do that all the time. Cause of the old folks dont ever get on them to CLEAN it out. its good every once in a while to beat on your CAR HEHE

stop with the wot and it will dissapear! (or uintil you have eough $$ for a new motor, then just tear it up)

wouldnt it smoke at every wot run all the time if it were the rings im thinking it may be the pcv no smoke out of teh oil cap and it seems to fire fine with normal ls1 oil consumption 1 qt ever 1000-1500 miles
