Picked up a nice 525i. Had a broken timing belt. Aftert taking
apart the head we found a damaged rocker arm. Was this a result
of the broken belt?? Is the straight-six overhead cam M20 engine an
interference motor?? If so, are there any special cosiderations
in bolting up the rebuilt head back on?? I have all new headbolts
but was wondering about lining up the cam if it was an interference
unit?? Anybody got the scoop here??/ THANX!!
