Smoke at start-up

Recommended Posts

My 2002 Carrera4 Cab occasionally emits a white cloud of smoke resembling fog at start-up. It doesn't happen every time and I haven't noticed a pattern to this behavior. The fog of smoke ceases immediately and there is no oil residue in tailpipes nor any foreign buildup in the oil filler tube or under coolant cap. Can this be from using oil with the wrong viscocity or do I have a mechanical problem? I believe the oil is 10W30 and I drive the vehicle in central Florida.

The approved oil is Mobil1 0W-40, the used viscosity, especially in hot conditions (30) is too light. However a small puff of blue smoke at cold start up is not uncommon. I would change the oil with the approved one to start with.

If the smoke cloud is very large and white it could be your AOS. Do a search here on AOS.. You will get lots of information. Agree with RFM, change to the correct oil first...

Hello All

I lie in Gloucestershire, UK and I have joined the white smoke club with my 996 C2 2002 TIP. Same symptoms as the others in the various threads here. Occasional white smoke on start-up after hard use only.

My question is this. I have been quoted approx 5 hours labour for the replacement of the Air Oil separator, plus the cost of the part, from an independent expert usually v trustworthy.

Has anyone else had the AOS replaced, and what were your labour charges/hours if so?

Any help welcome.

Five hours is more than reasonable epically considering the fact that you drive a TIP. I have a feeling that once the job is complete he'll wish he'd charged 6. The manual has way more room and really can be done quite easily but a TIP is a nightmare.
