Carrera startup smoke - problem solved!
 

Ellsworth Wente posted this on Rennlist a few weeks ago, and I've been trying it. So far NO startup smoke.

"I have had the same problem on my 87 with 126k. some time ago I read either here or on Pelican about letting the car idle for the 15sec or so it takes for the oil tank to fill back up after driving before shutting off the ignition. I just watch the dash oil level guage until it floats back up to midline, then shut it down. In theory this lets the oil pump push most of the excess out of the engine and back to the tank before turning it off. FWIW I've found that doing this eliminates the starting smoke puff about 90% of the time. Just something else to try...."

cool, ill try that tonight.

Wow, cool, I posted that 10/18/02. http://forums.pelicanparts.com/porsche-911-technical-forum/84560-puff-smoke-start-up.html It works for me, not quite 100%, but it does seem to make a pretty big difference.

You guys sure it isn't your Valve guides? ;)

Never saw this tip before. Thanks, I'll try as well.

At the last valve adjustment, my guides seemed fine (using the sideways wiggle method). Plus the car uses almost no oil between changes (<5K). The puff of smoke at startup has been the only oil use issue. Car has 71K.

Ahh, smoke at start up is just a good way to clean out the mosquitos in the morning...
