Hi There, I'm new here and have a question that may have been asked before, if so I apologise and please direct me to the answer. Q: I have an E39 M5 85k miles but I have to change the timing chain, my mechanic reckons the he can change by attaching the new chain to the old and pull it through. He know's his stuff but I have reservations regarding this step. Don't get me wrong if this is ok to do,ie won't effect tensioners or vanos then I have no problem but if there is a chance this will srew the engine up and cause more problems I woud like to know. Thanks in advance for you help... Gerry

Sounds like a bit of a botch to me. You have a specialist car that deserves specialist attention when it needs new bits. Timing chains are replaced by fully removing all the timing chain covers and removing the tensioner so it can be lifted off in one piece. If the new genuine timing chain part comes in a length rather than a loop so you have to join it yourself then fair enough but if it comes as a loop then get it done properly. A join in the timing chain carried out anywhere other than the factory that makes the timing chain will then be a potential weak point in the chain. I would get it done properly, if the timing is out, your engine is only good for making tin cans out of afterwards. ------------- Be exclusive and drive a Petrol 5 Series!

Hi Guys,
I agree with both of you whole heartedly, it's been a while since I have owned an M power car and reckoned there was a new technique developed. The car is sweet though when she is idling she sounds somewhat like a diesel. The mechanic had a look and determined it was the timing chain. I am living in Crosshaven Cork but work in Leixlip any recommendation would be welcomed. Thank you both for taking the time to respond.

If a V8 petrol engine sounds like a DIEsel then in my world something must be seriously wrong as only an X Factor contestant sounds worse that a DIEsel engine

It could be chain slap you are hearing, but rather than go straight in with a costly timing chain change I would change the tensioner first.

These guys are all a bit further in to town but their reputations as BMW specialists are good and from what I know they should all be well familiar and experienced with M's.
Bloomfield are a slimmed down version of what used to be known as AC Car Sales and were around Dublin 8 and out on the Naas Road for a while under that name.

These guys are also BMW specialists but I'm not sure of their experience with M's.

Just make sure that they know what they are doing with an M5 engine. if its anything like an M635 engine, which I assume it is, then its a major bit of work, and not many dealers are qualified to undertake it. Engines have moved on since the M635, which used to cost around £1200 to change the timing chain at a specialists (BMW Dealers usually don't know how to do it) and the following may not apply to the newer E39, but usually its worth doing all sorts of things to the engine as the work involved in stripping it down to fit a new timing chain is quite extensive.
