A bad month.

cav551:
it looks like the timing chain has slipped a tooth

Is it a 318 ?

Sounds like a “valvetronic”, fairly common problem on that engine.
If you catch them early its not a big problem, if you don’t, the chain guides usually get broken.

The problem is with the tensioner. Make sure you replace the tensioner with the “New improved” one.

Oh yes a poxy N42 engine.

Thanks for the warning, it is certainly going to get a new ‘improved’ tensioner anyway. It has broken the top chain guide which is a good hint that the timing has slipped apart from P 0015 (I think that’s what the code was). I am just really looking forward to the prospect of hanging the thing from a skyhook in order to change all the guides and the worn chain.

Evil piece of dog’s doo doos.

As a word of warning to anyone else interested, this has most likely been caused not just by the useless tensioner which runs out of ‘throw’, but by using fully synthetic engine oil and then (and this is the important bit) going right up to the oil company’s much publicised extended oil change interval, without realising that this only applies to vehicles like taxis which virtually never get cold. If you drive less than 20 miles to work etc per journey this is counted as heavy duty operating conditions which require far more frequent oil changes.

…which reminds me…I must change the oil & filter on my diesel B*W as it too is on 20,000 mile intervals just to keep the fleets happy…
