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.

Yes i think thats good advise.That a lot of damage for one event. I can only imagine the sound that made. good pics too. I have two m50 h/g blown engines on Dolly's for the day i decide to rebuild one.

Wow, that's comprehensive. Bad head gasket, yyea. Perhaps mail a valve head to the seller

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

reminds me i have to do the one on my M40 in my 3er sometime in the next 6 months. ergh. its not a difficult task on either, ive done it several times, but just so time consuming!

south26 01-23-2013 06:32 PM

but not doing it is some much more time consuming.

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