Just put 1000 miles on my SC400 in the last 5 days. Damn I love this car. Spent 4 days in San Diego. Anyway, on the way back to Vegas I noticed some white smoke coming from the exhaust. It doesn't do it all the time. In fact, it only happened 3 times from what I could see. It will blow a puff of smoke and then not do it again. Any idea what it could be?

 

Coolant - you've got a leak! Get it fixed quick! Headgasket is going, or timing cover or something. Check out your engine bay, look around and undrneath at the seals to find where the fluid is coming from. How is engine temp. - do you smell anything after you drive it?
