hey guys hit a snag in my l 18 rebuild and was hopping someone may help. i broke a bolt on the rear main bearing when i torqued it down to measure the journal. all of the suppliers i have asked tell me that they are unable to get l 18 main or head bolts and can't tell me if the l 16 or l20 bolts are the same. has anybody else had this problem or can someone tell me if these parts are interchangable. from memory the main bolt thread patern is m10 X 1.75 x 75 long.

edit:- may be 70mm long

Quote:Have you asked your friendly Nissan parts man
He should be able to compare the part numbers for the bolt in the three engines & I would not be at all surprised if he could supply the new part, although you may have to wait a couple of days.

If one bolt broke, then have a think about the possibility of some of the others also suffering from the same problem that caused the broken bolts demise. [over tightening?]
Think about replacing them all.

thanks dodgeman i intended to replace all the bolts anyway. as i stated in my original post suppliers i have talked to havent been that helpful, perhaps im not asking the right questions. does any body in brisbane know of a reputable supplier who may help?
