My vauxhall combo smokes quite heavy and has done for 13 months allways passes mot but getting mad about it now what could it be fuel pump? Injectors?I keep changing things allways serviced but cant get it to not smoke timing chain was allso done 5000 mile ago?
Heave the valve seasl checked for cylinder leakage we have no info on this car. Also if a turbo check that for a bad seal.

I had this problem, I had put a bit too much engine oil in, check the level and take a pint out, other problem I had is that I found that if I changed the glow plugs it stopped, especially on start up, check each plug individually by taking out and reconnect to electrics, see which ones get hot, replace the ones that are cold. Will start a lot better too.
