4106 Engine Trouble? Weird Crunching Noises...

[OneLapper]

There shouldn't be a lock washer on the bell housing all those are copper or flat steel washers on a aluminum bell housing that fitting is used where the spacer goes between the bell housing and the V730 a return line

Thanks Clifford!  I put back what I removed, hence the lock washers.  I'm pretty sure I used blue loctite on those three bolts, but I must have not tightened that one down.  Hard to believe I could make a mistake like that.  I even used a paint pen to mark the bolts after I torqued them. 

I feel better now that I've likely found the problem.  I'll rent the garage and pull the tranny this winter to fix these issues.

Thanks guys!
