peugeot 406 timing belt slipped? - leerichmond21
peugeot 406 1.9dt i have got abit of white smoke coming out the exhaust from cold starting and a knocking sound coming from the engine, the revs on idle are also reving up and down and are not steady, could this be caused by the timing belt slipping a tooth? any ideas?

my car has recently started knocking from the engine and the revs a constantly reving up and down when idling. it also has got a little bit harder to start, do you think the timing belt has slipped?

any information would be much appreciated

Dont know much about the white smoke and idle, but when my cam belt slipped a tooth it was very difficult to start (VW Passat 97).

It does sound like the timing has gone out, but I can't see how the belt on one of these would jump a tooth - it would be more likely just to fall off. Checking it means you really need to take the engine mount off to get enough room to get the covers off and the bolts in. If that reveals nothing then you need to look for evidence that the injection pump has moved - checking this needs specialist tools, so best entrusted to a diesel specialist.

Another possiblity is that you've got an injector sticking. I understand these can make all sorts of racket and running problems, but don't know how you'd diagnose.

Is it illogical? It must be Citroen....
