Have a 90 200 tdi which has started producing lots of white smoke in the exhaust gas.
Have checked the following:
cylinder compression, maximum difference between adjacent cylinders only 20 PSI (70 PSI limit), so that's ok.
checked injectors by loosening union on each one in turn to see if the smoking would stop, it didn't.
Glowpulugs and timer unit, all ok (plus the smoking can go on for some time longer than just warm-up time)
Checked for water in diesel, no. Checked for petrol! in diesel, no.
Checked hoses to and from turbo (for air leaks, similar problem on audi once which produced white smoke, simply becasue not enough charge air was reaching the cylinders), all ok.
Suspect timing belt may have jumped a tooth or the injection pump is to blame.
Engine starts as easily as any 200tdi. Occasionally when revving it sounds as though you get a misfire only very briefly and then it's fine, but still chucking out white smoke.
Any ideas?
