1998 Acura NSX Exhaust blowing white smoke

I think that if you change the oil and inspect it that might tell you a lot. Look at the oil if you see water or foam then it might me a blown head gasket. In cases like this it is important to get some testing done. Check how low your coolant is after every time you drive that will help you know whether the coolant is leaking into the combustion areas. Look around the head you know where the head bolts to the block and look for yellow or green seepage or stains and touch it and smell it. White smoke means you are burning coolant with gas. That is a blown head gasket. Park the car and change the gasket if it is a lot of white smoke all the time you drive. A little white smoke at a cold start up in a cold place is normal for a few minutes. David Newton please donate $5 if this helped you
