Yeas all cars got timing belts that should be replaced around the first 100,000 miles . . .
I'm not sure of you just worded your post wrong, but I just wanted to clarify that not all cars have timing belts; however, his is an M20 engine so it does have a belt.
I would agree in going ahead and replacing it since you probably have no idea when (if at all) it has been changed. I'm not sure if the M20 is a "non-interference" motor, but even if it is, you wouldn't want to be stranded due to an old broken belt.
It this is an m20 engine, then it does have a rubber timing belt, and should be replaced every 50k, technically is around 70, but do it on the 50k just in case.
Also once youre in there, replace the timing tensioner, water pump, thermostat. pretty much everything that is on the way take it out to ensure no failing on the future, also you will have to take the distributor out so if its never been replaced, goo time to do it, you know it gets old, burned cracks.. etc. also replace the top seal camshaft, this will prevent oil leaking behing the distributor. Th ebest thing to do is to look for the procedure on service manual, like bentley best one out there, or the internet, such as www.bmwe34.net
look under maintenence.
But in case you have an m50 engine, it uses a metal timing chain that goes inside the engine case. I do recommend to change the timing chain tensioner as it normally fails around 90k according to word on the net, is not that expensive so replaced it anyway.
Accroding to BMW service manual, and even bentley, the timing chian must not need replacement. just make sure youre using good oil and that is up in the full line. Also if you hear a tapping noise on the cold starup, and i mean cold, close to freezing, you might hear a tapping noise that goes away after 2 , 5 sec, this is the hydraulic lifters that this engine uses and they do a little noise till oil pressure builds in and pressurizes it, and this is an anying noise, considered normal. Ive had this issue, look on a question i posted, it has a video with the noise. and after looking on the net, post responses and BMW service manuals, it all indicated normal noise from cold morning coming form the hydraulic lifters.
BEst thing you should look on ebay to buy is the BMW cd set. It has Parts catalog and service manual catalog, look under BMW etk.
To own a BMW and be able to service you need 3 basic things,
A Bentley Service Manual, AKA the bible,
BMW ETK Parts cc.
and a set of craftman wrenches and tools. ( Hey I started with a walmart screw driver set and a craftman wrench toolbox, and now i have a 4 drawer Snapon toolbox weightin around 100 pounds with all the stuff on it..
Yes BMW are a legal drug, and im loving it.
