i have a 1994 bmw 525 . i bought it knowing it needed head work . i replaced the head gasket put it back together it ran but could tell it was still leaking. pulled head again head was cracked had it welded and rebuilt . put car back together it will not start . the timming marks were lined up # 1 cylinder up . how do i know where to put cam shaft as far as timing goes. i think they are the same as when i pulled them . also when i put the head on the 2ed time i pinched the crank position sensor alittle . the wire looks shielded and that is the part of the wire i pinched the shield and the outer plastic not the main wire so taped it up and went on . does any one have any suggestions?


thanks pat
