Timing chain replacement

[pbgd3skier]

sure yours hasn't already been done during that 160K?

Just pop the valve cover and take a look at the sprockets. You'll know if it's been done recently as the teeth will be squared still.

When I replaced the timing chain on a motorbike I used to have I just took off the rocker cover, used an angle grinder to cut the chain, and rolled in a new chain. The new chain didn't have a link so had to be cut and a link was purchased.

If the sprockets and guides are in good condition then I don't see a problem.

But that's not the same thing.

If the chain is worn, then so are the sprockets, the nylon guides and the tensioner.

They must be changed together so they wear evenly together.

Positive.

The chain started slapping around a bit more than I was comfortable with so I got another car to drive.
There's no rush now so I think I'll just take it all apart and replace the parts that look worn. I'll take some pictures when the time comes and you guys can tell me what you think needs replacing.

I asked BMW if they had a timing chain kit and they don't, Pellican Parts and BMA have all the OEM parts at a way lower price than BMW anyways.

Wish me luck!

On a motorbike your chain is not encased and doused with engine oil. All that metal and dust will destroy your oil pump.

Plus on a  motorcycle you have 2 sprockets. Both of which are relatively easy to get to. On here you have 4, which are difficult to get to, difficult to feed, and they have to be times.

Little different.
