Coil snaps head stud (No replies)
My friend Chris Lee had an unexpected and unpleasant experience with his RSP. The bracket that carries the coil sheared the head stud to which it attaches, the fracture was level with the top surface of the head.
It is assumed that the constant alternate loads on the stud as the car bounced up and down caused metal fatigue. The head had to come off anyway as the loss of clamping force caused steam to escape so the condition of the gasket as unknown.
The coil bracket is now attached with one of the flywheel housing to block bolts.
Might be worth checking
