M50 timing chain mileage

[Espen]

How long can the timingchain last? My car have 230 000km now.

Should I get it replaced? Is that something I could do myself? What parts do I need? there are 3 chains right?

143k miles is young. There is no need to replace it at that mileage. Yes there are three chains. The secondary between the two cam sprockets, the main between the exhaust cam sprocket and the crankshaft, and one between the oil pump sprocket and the crankshaft.

The chain should be good for the life of the engine.

I hear the same thing when i asked about that regarding my previous car, a ford sierra with a 2 litre dohc engine "nah that chain lasts as long as the rest of the engine"

"Bang" at 205 000km the chain snapped, and I had to buy a new engine.. ;)

Just want to make sure this is not true for the M50.

they are made to last a very very long time....this isnt a Frod.

Ok... I saw a "high performance" chain kit at a local bmw tuning shop.
They said it was a must for bmw`s with a chip. (higher revs)

LOL well if your putting out 1100hp I WOULD recommend the new chains

bottom line this isn't a ford where you undo 3 bolts and it falls off, the chains require a decent amount of mechanical ability, as well as some special tooling- one just to hold the cams in place IIRC.
