The oil is fine.
But I get white smoke only at idle, but it stops.
The first time was about 2 weeks ago. I pulled over, but as I drove to pull over, it stopped. Did not do it again until tonight. Once again it stopped. If it was a blown gasket, wouldnt it smoke all the time?

 

Could be a leaky head gasket. It'll probably blow the first time you get on it really hard.

 

Your best bet would be to do a leakdown test.

 

Whats a leakdown test?

Weird, I drove the car to work today. Drove it pretty hard. Took it up to 8 lbs boost a couple times.....and nothing.

 

No offense but I would not recommend driving the car hard until you find out what is wrong with it.


It basically will measure the amount of blow bye. You are basically pressurizing each cylinder with a known pressure and measuring the amount of air that is leaking. This could be due to bad rings, valves not seating properly and popped head gasket.
