My dad is uprgading from his 912E to a 75 911s with a CIS 3.0 as an autocross car. He is doing this because he is tired of loosing to my 914 and because he cant mod the 912E due to Smog because it is a 76. My question is the motor puffs a rather large cloud of smoke out the exaust on startup concistantly hot or cold but has a totally clean exhaust while running and reving. What would cause this? the motor is supose to have about 30K on it and AASE Motors verifies that the wear on the engine looks to be about this milege while they were replacing the head studs. The only thing that i can come up with is that when the motor is not running some of the 11 plus quarts of oil sitting above the engine runs back filling up the bottom of the engine up to the pistons with some oil leaking past the rings. Is this possible? It makes sence to me because the oil tank gadge goes up (reads more oil) once the engine is started and the massive scavenge pump kicks in. Have any of you 914-6 guys experienced this? Would moving the oil tank to the front solve this? My dad is realy bumbed about this smoke because this engine alone costs more than the entire 912E. Makes one realy appriciate the simplicity and reliability of the T4. I do not know if it makes a difference or not but it is baised on a 3.2 case with the Carrera pump.

Almost all of them do that. I would say all of them, but I try to be careful not to pass on erroneous information- "some guy online said..."
there might be a few that don't smoke on startup, but I haven't seen them. Everything's fine, as long as we're not talking about filling your garage with smoke so thick that the neighbors call 911. |
