Smoking 964???

I posted this issue on the 964 board a few days ago and got one response.

Wife drives this car. Last night she took it through one of the spray car washes to get rid of the pollen. After the car wash the car began to smoke. Bluish white smoke from the exhaust pipe.
I know on the older, my SC for one, cars an overfilled oil tank will smoke. This is acting exactly like that. It even smokes on a hard right turn worse than any other time. Poor lady behind me had to think she had pulled out behind James Bond...
This car has close to 200,000 miles on it but never burned oil before. Leaks yes but no burning.
I did take the air filter out and look down the throat of the intake. No signs of oil, but it is acting like oil being ingested via the intake.

What happened at the car wash?
Oh, I did check the oil etc. and it seems all is normal.
I did a search and none are quite like this.

Thanks,

presuming you did have an overfill the oil would be making its way back though the intake to be burnt off even if you can´t find it. I´d recommend draining off a quart immediately and then checking the level again when the car gets up to temp. The car washed might simply have washed oil from somewhere onto the exhaust parts. I´ve heard of an oil leak in one of the front lines washing oil into the tray on the underside of the car. Have you checked for any possible leaks?

Can't see a possible connection between the car wash and the burning of oil through the engine. The blueish smoke (for sure) is coming from the exhaust pipe, as opposed to coming out of the back of the car? As was theorized on an earlier post, if the smoke is coming from the back of the car you may have an oil leak dropping a lot of oil on the exhaust. ( I know what everyone is going to say "but that's impossible, Porsches don't leak oil"). Don't have anything else. Cheers

Thanks for the responses.

I agree 99% that the car wash had nothing to do with the car burning oil. It is definitely burning oil. Not burning off leaking oil. It also gets worse on a right turn, which is what I know my SC did when the body shop topped off the oil for me. GRR
The oil level is mid way on the stick. I could drain the oil and pour in 8 qts knowing that would put it at the lower end of full. Before I do this, I would like to see a trail of oil from the tank to the intake. On the SC, inside the breather, was flooded with oil.
It is definitely getting a steady diet of oil from somewhere.

Kevin,

How do the valves sound? Our 993 did puff some blue smoke right before we had the top end re-done due to the valve lifters and some other items.

I do not know if this is it but could there be oil getting by and being burned off?
