It may be a dumb question. Friend of mine's 1982 300SD is blowing white smoke when starting from a standing position, say from a stop light. It seems to be OK when moving or at freeway's speed.
The link below suggests the turbo may be leaking oil and it is spool inside the turbo during idle. When the car starts moving the oil is burnt and emitted as white smoke.
white smoke-definitely OIL
Can I do a test to by-pass the turbo or remove it to see if there is any white smoke? We have pretty much discounted head gasket but will do a pressure test on the radiator to be sure. Compression seems to be good as the car starts very easily.
Any info is appreciated.
