Z928328

If you guys recall my car had a crack block and the car have been in the workshop since. I manage to sources another block and head from another 928 around here.

Today I test drove the car as the rebuild is done. The mechanic said i needed few things which is The fuel pressure regulators, Oil pump sensors and injectors.

What I notice today is

When He starts the car- The car will produce a puff of dark grey smoke from the exhaust. and the smoke will be gone during idle.

During traffic,I followed the car from behind- What I notice- The car will have some smoke from the exhaust at certain times. Eg. Stop at traffic light -and you press the gas pedal I saw the smoke coming out from the exhaust and the smokes stop. and smoke will comes out randomly sometimes during drive at traffic. During idle or at low speed- No smoke at all i notice

I ask the mechanic- He said I must drive it at least long distance for a while then it will be gone. Then I will have to bring it for the first service.

Ideas? The smoke smell a bit like fuel but i'm not pretty sure.

I've spend so much already on this car.

FYI- 2 times the engine is pull out because of non stop smoke from exhaust during the 1st time rebuild due to the original head is crack

Blue smoke = Oil
Black smoke = fuel
White smoke = $$$$

What does the smoke smell like? In other words, does it smell rich, or like oil, or something else?
