help, my 911 is smoking
I started my 1970 911T (with 1969, 911E motor with webers) up after a month of being dormant while I made repairs (brakes, suspension-no work done to the engine). I didn't notice anything until the car warmed up and I pulled out of the driveway. I soon noticed a large cloud of smoke that was bad enough that I can't drive it. I tried to determine if the smoke was blue but maybe due to lighting conditions, I couldn't tell if the smoke was grey/white or blue. I will have to look at it again but I was wondering if the rings and/or valve guides were worn, wouldn't it start smoking right away as opposed to getting worse after it has warmed up?
any thoughts? |

If the car sat for a long time, oil could have accumulated at the bottom of the cylinders, and get burnt while passing in the combustion chamber if the rings do not seal perfectly. That would be blue smoke, and it should clear up after a while. One can also envision that moisture got trapped in the exhaust, and that would be white-grey smoke that should clear-up after a while too.
The best way to check if the rings-valves guides are worn would be to to a leakdown test. If that is the case, it would smoke when warm for sure. One more thing: did you add oil? If you overfilled, that would make it smoke too... Aurel
