Timing chain cover studs or bolts?
My 400 I'm putting together (torn apart and no hardware when purchased) looks like it's suppose to have studs, (2) on the timing chain cover and two bolts. The stainless bolt kit purchased from Butler just has bolts. Is this ok, or is there another reason for the studs (something else bolts on, etc.)? Also, is there a need to seal the threads or do those threads just run into a blind cavity?
Also, my harmonic balancer has a fine groove in it (almost looks machined). I assume this is wear and needs to have a sleeve over it for the rubber seal to seal correctly. Unless that is the way it's suppose to be, but I doubt it.?
