like the title said my 05 has small crack and small hole in a bell housing , it looks like from exploding clutch , did any one had the same problem and do i need to change it ? it drives normally

 

Once or twice I've seen a clutch explode and severly damage the inside of the bell housing.

Also, I have an evo that's been wrecked, not too major. In the wreck, the bell housing was cracked in 2 small places. I'd say if it drives ok, you're probably fine. You could probably get it welded up.

 

Hmm what type of clutch/flywheel combo were you running? How many miles before it exploded? Have you had it apart yet, I've seen a few but they were mainly brand specific
