90_300TT Smoking Like Crazy
I have a 90 300zxTT 5-sp with 230,000 miles (original turbos!!) Recently, I took a trip of 450 miles with no problems. The next day, I started the engine and after about 10 seconds there was a large amount of white smoke from the exhaust pipes (maybe 20% more from right tailpipe... but both were smoking) but it idled normaly... It was like a James Bond smoke screen;-). I checked the oil and water for signs of mixing and didn't see any. I found that after the car was running for about 10 or 15 minutes, the smoke would stop, so drove 1 mile to an oil change place. The car drove normaly. It turns out it was 1/2 quart of oil over but there were no clues in the oil itself. Since the car stopped smoking, was running normally and wasn't overheating, I decided to complete my trip (another 450 miles). No problems.
The next day (car was cold) I started the engine and the same problem occured (smoke) and, as before, it stopped after 10-15 minutes... Next day, same thing.
So, any ideas on how to troubleshoot this?? Any help you can give would be appreciated. Thanks in advance!!

I had the same problem about 6 months ago on a 90 with 80 on the clock. I got someone who has a GTR to look at it and he said that sometimes this happens. Can be a bit of residue. Apparently you only need to worry if it keeps doing it over a longer period.

You could possibly have a blown head gasket. That would be allowing water to get into your cylinder heads and burning off through the exhaust valves as steam. That doesn't explain why it stops after a while, but its somthing to look at with a car with that many miles.
Hope that helps,
