ok well my sr just recently started blowin white smoke i pulled it from my hatch and it was fine i put it in my coupe not even 5 min later and now it blows white smoke real bad.It still runs like a beast no problems at all spools fine doesnt over heat and it has power.the only thing i could think of was old gas in the tank or maybe that the station i gassed up at has 10% ethenol?? could that be it? ive been tryin to run it out but the cars not legal and it gets damn good gas milleage. im open to other possibilities i want to catch the problem if there is one before it gets worse............thanks input would be great

 

Does it blow white smoke when your driving or just sitting still?

 

if it only smokes at startup/idle, then check the valves out.

if it smokes all the time, could be a bad headgasket.

it could be running lean, check EGTs and AFRs

 

Why check the valves out for white smoke?

99% of the time, white smoke = blown head gasket. You are burning coolant.

 

How is it people still don't know the effects of running E10? Ethanol won't make your damn car smoke.

 

not valves, but valve seals. my car produced a white colored smoke sometimes on constant higher rpms because my seals were going bad.

 

because if your valve seals are worn, oil can slip into the combustion chamber, and then burn up causing white smoke.

or i could jump to conclusions.

 

Doesn't oil cause blue smoke?

 

yes ^^^

but i have seen clouds of white smoke at idle and found the turbo to be at fault

 

Well turbo seals hold back both coolant and oil (unless the turbo doesn't use coolant, I'm not exactly sure how many do/dont), so coolant can be burnt in a turbo as well.
