Smoke Problem
 

I have the occasional smoke problem at start up but this is more serious. I track the car a PCA DE events and sometimes after a hard turn, I get a tremendous puff of blue white smoke from the exhaust. If I run hard enough to get the PSM to kick in, the problem gets worse. I was black flagged once. This has also caused a sensor to fail and I get the check engine light. The car is fine and still runs great even with the light on.

Any help would be greatly appreciated.

When was the last time you had the spark plugs changed? I've seen that color smoke before come after a sparkplug had gone bad. What code did the check engine light give you?

How full is your oil?

Are you using any oil?

Is your coolant clean and free of oil (no brown foam)?

Is you air/oil separator system in good shape?
