Can anyone please tell me the symptoms (more noise, loss of power etc) of a diesel injection pump with the wrong timing (too far advanced or retarded)
I have 2 rover 218 cars, one has the citroen 1.9 non turbo engine, the other has the citroen 1.7 turbo diesel engine.
They are both noisy (diesel clatter) when cold, but when warm, the 1.9 quietens down, but the 1.7 is still very clattery at idle and under load. also the 1.7 has no bottom end power until the turbo starts boosting. the 1.9 has a lot more bottom end power, but obviously is not as lively at the top end due to lack of a turbo. The turbo engine gives 11 psi boost maximum.
I haven't noticed either car emit black, blue or white smoke.
The air filter is OK and the new fuel filter i fitted to the 1.7 has made no difference.
Does it sound like an injector/pump timing fault or something else.

hi,
i own a peugeot 306 dt & have had the same probelm. The only was i could fix i was to "thrash" the car, This means taking the revs up to 4900rpm in 1st - 3rd gear. Doing this when cold will omit any black smoke which has built up inside the engine which is not visible when driving. Keep giving your car hard revs for around 1hour then see if the problem sorts its self out,
any more problems, e-mal me

fm,
>Can anyone please tell me the symptoms (more noise, loss of power etc) of a diesel injection pump with the wrong timing (too far advanced or retarded) - Pump settings need correct info and special(ish) tools.
>I have 2 rover 218 cars, one has the citroen 1.9 non turbo engine, the other has the citroen 1.7 turbo diesel engine. - In the Rover these engines feel/sound rougher and can feel more sluggish than in almost any other Cit/Pug model.
>They are both noisy (diesel clatter) when cold, but when warm, the 1.9 quietens down, but the 1.7 is still very clattery at idle and under load - I assume these engines have covered 100K or more?? Depending on past maintenance some will still sound dead smooth at this mileage, others sound clapped out.
>also the 1.7 has no bottom end power until the turbo starts boosting. the 1.9 has a lot more bottom end power, but obviously is not as lively at the top end due to lack of a turbo. The turbo engine gives 11 psi boost maximum - Sounds exactly how they should be with the normal 1.7TD turbo lag.
>I haven't noticed either car emit black, blue or white smoke - So they aren't that bad at all then.
>The air filter is OK and the new fuel filter i fitted to the 1.7 has made no difference - No it wouldn't.
>Does it sound like an injector/pump timing fault or something else - I haven't actually seen anything I'd call a fault in your post.

Assuming Marsden1002's advice of an italian tune up didn't work (Revving hard)although I suspect this helped if you are a gentle driver, then as follows:
Retarded Pump timing: Less power less noise less smoke(to a point)
Advanced pump timing. More power more noise more smoke.
Obviously, if the pump timing is tweaked too much either way, it won't run at all.
I suggest finding your local diesel specialist (not Rover dealer) and talking it through with them. I'm sure they could diagnose if there is indeed a fault.
