ok peeps i just rebuilt my top end i had an oil leek from some where so i just started it up it ran soon as fuel got into the carbs i rev it and there was 1 small pop from the engine then i noticed oil all over the floor i noticed the oil filter was loose but i never touched it on the rebuild at all the thread on the bolt is stripped so could the pop i heard been the bolt popping out is if could there be anything i,ve done on the rebuild to corse it to happen

Nurse Julie:
Has the engine been out of the frame with the oil filter housing sitting on the floor?. Has the thread stripped from inside the case as well as the bolt?

McCabe-Thiele (Ted):
Ouch that sounds bad hope the thread in the engine case is okay and it's just the bolt that's been hydraulically expelled.

not been on the floor and yes thread gone on bolt and case not a happy chap i spent 8k building this bike with all new genuine parts that took 10 years to find now i,m trying to find some engine cases with the same letters on the bottom case so i dont have to work out and find some new shells again

Oh dear, what a bummer. I must ask though, did you do a complete 100% engine overhaul without removing the oil filer and housing?. If it were me, I would want to know what has happened within the engine to make the filter bolt and the case threads give way like that.
