Hi Mates,
I am asking for advise, I have an Y61 ZD30 DI automatic from 2000, it is powerful starts by 180° turn of the crank in -18°C, no water consumption but:
5-10 sec after start it starts to smoke white, it smells bad but I can not decide whether it is diesel or what. Once it is totally warmed up there is no smoke at all, it is running better than I would expect from a "grenade".
I've checked the CO2 by gas marker in the cooling circle: no exhaust in the coolant and it is quite clear.
I have increased the pressure on idle up by a pressurizing tool to check if there is any reaction (perhaps more white smoke if it is gasket or head) but no change.
So I believe it is not vapour in the exhaust smoke.
I have checked MAF but it was very clear, no oil residue or burned fiber from the filter.
I will make a compression measurement this week, but I do not think that this will bring any deviation to normal.
Pls. advise how to proceed further, could it be deposit on ring grooves, or injector, or the pump or what else?
