start up smoke
Does anyone's 930 give some blue smoke on start-up (cold). Once warm, smoke goes away.
Is this normal, or indicative of a turbo seal going? Thanks |

How much smoke? How long does it smoke? Does it do it everytime it starts cold? Does it ever do it on a warm motor start? Was the engine recently worked on, and it started smoking? My experience with Turbo seals are that they smoke like you are fogging for mosquitos if they are worn out! Valve Guides and seals can smoke. Guides if they get bad enough will also do it on acceleration. Boxer motors can do this a little anyhow sometimes. I do no Turbo "Cool Down" on mine because I have been off boost at low RPM for some time by the time I get to my Garage. If you are doing this turbo cool down BS it may be causing your issue. You may try this as your new shutdown procedure: When you are parked, bring engine RPM's up to about 2000-2200 or so for about 5 seconds, and shut down the engine while it is at this rpm. The idea behind this is that the scavenger pump is not efficient at idle and may allow the Turbo oil accumulator to fill with oil and cause a small pressure induced seepage across the turbo sealing rings. You burn this seepage on the next start. Give it a try and let us now. Also let us know what you mean by a little smoke on start-up.

Just wondering I a car i am thinking of purchasing. Not really sure abut all the specifics. I may have to talk to the seller a little more.
Supposedly there is no smoke on acceleration and deceleration, so this may be a non-issue. |

Normal and not uncommon. But to prevent being flammed, do a PPI even though I never have. Lucky I guess. The big thing to watch for is blue smoke on decceleration.

Mine does this also. Has a new K27 and the motor was rebuilt 20,000km ago.

Hey guys (and maybe girls). Thanks.
My wife and I have been looking for a car for a while. This one seems really nice and I am willing to pay for the excellent condition. Obviously I will invest in a PPI and my own inspection. I am not scared of turbo repairs, as my job, rotating equipment engineer, allows me to rebuild and have access to balancing equipment (when needed). But, I would prefer to get a car we can enjoy for a while before we need to put additional $ into it. Hopefully all works out and my 914 will have an over powered, absurd cell mate. I really want this car for life. We plan on keeping it pristine, but we will drive it. I do not believe in showroom collector cars of any mark. Once again thanks. If there are any more comments, I would appreciate them. |

The 911 engine can smoke and is normal when you start from cold but it shouldn't last long at all, less than 5 secs. Longer than that and there is a problem of some sort. Could be engine or turbo.

I don't know about 5 sec being long but I wouldn't expect it much more, if any more, then that. Here's my car cold. When I say that it was rolled out in the driveway after sitting for a couple of days. This is for sure normal, but I wouldn't expect it happening much longer then that or I'd be looking for answers...

Actually, I think Les is right, I was being too generous. Maybe 3 secs is more realistic.

I think your Video captures a normal "puff" perfectly.
