Chain. Don't think BMW ever bought into timing belts.

Maybe 325i between '87 and '91 and some 5 series as lates as '95.

Your previous car must have been a Honda!

Yeah belts suck. I replaced one on my WRX. Had to take out a hell of a lot of things to get to it. Twice because I left out one of the waterpump bolts after reassembly. :P

The M20 engine uses a timing belt. BMW used variants of the M20 from 1977 until 1993.


The M20B25 powered the 1989 and 1990 e34 525i. From '91 on the 525 used the M50 and that engine has a timing chain.

I think the last year for an M20 powered 3 series in the US was 1990 or 1991. After than the 325i also switched to the M50 engine.

The same here as well. Im learning too but good to know I need a chain. I was told I had a belt because it needed to be changed and was sprayed for it to last a little longer until I get a new one but BMW swears I have a chain?

I have to assume the belt to which you refer is the accessory drive belt. There is a belt to drive the alternator, water pump and power steering. The timing chain is internal and drives the camshafts.
