Puff of smoke starting 5000TQW
My '86 TQW with 133,000 miles recently started dumping a good puff of
smoke on cold startup. It happens about 70 percent of the time. I
wouldn't be so concerned except it has also started using oil. Not
visable blue smoke, but about a 1/2 to 1 quart to every 1000 miles.
I've had other turbo Audis with higher mileage that didn't use any
measurable oil so I'm a little concerned. I can see valve seals
possibly causing the puff of smoke, but what about the oil usage? Are
turbo seal failures a possible cause?
Thanks for the input.
