reasons to change your timing belt on a m20

Hi, I was taking a head off a m20 from a e34. I bought the car to part out. I was told that it had a blown head gasket. Well I have never seen a gasket go like this. I did not count but a number of rockers broke. 6 valves broke, one stuck in a piston. 4 out of the 6 pistons had holes in them.




















Remember change your timing belt.


Andy

Ahhhh .... the joys of an interference engine with a timing belt (that is not properly maintained/changed out)

Does this apply to the M30s as well?

Nope the m30 has a chain. Only the 89-90 525i has the m20.
