Exhuast Stud

[logo]

Dyna has now done around 30k so I thought that I would take of the cam
cover and look at the cam chain tensioners. Failed at the first hurdle
despite loads of heat I was unable to undo the nuts holding the pipes on the studs in the head without risking the disaster of a broken stud.
Would I have a better chance using a impact driver or is this just as likely to break a stud?

thanks pete

Sorry to hear that LOGO, BUT from your description "despite LOADS of heat" Me thinks you may have caused the problem in the first place
TOO much heat will expand BOTH stud & nut which will then cause it to just shear at it's weakest point ie, where the stud enters the head.
Patience is a virtue, so next time keep soaking the ferkers over a 24hr period or don't get so hot headed with the heat, remember it's the nut that only needs expanding.
Hope you get it sorted soon.
