1988 316 1.8 auto m10 belt or chain

[teatime39]

Hi guys , I've looked through tons of old posts looked on the net to find out if i have a timing belt or chain , i feel a bit stupid not knowing but how can i tell one way or the other

Chain

[teatime39]

thank you John , what is the life of the chain as the car has 150,000 on the clock

The chain doesn't really wear, but the cam sprocket does. If it sounds rattly, it probably needs a new one.

is that an easy job , my knowledge of enngines is limited but am quite able to do the work if following instructions , are special tools or equipment needed?

[johnl320]

If its quiet I would leave it alone, unless you plan on keeping the car for a very long time

[teatime39]

I will be keeping the car for sure , it does sound a little tappy but to be honest there are other things that need doing , weber carb refurb an oil leak among other little bits ,
