Update on Columbia/Mercedes 4000 blown head gasket

[Chamberpains]

Again, if broken head bolts are common I would inquire deeper. If you have potentially 30 bolts that can't do the job for the long haul then go find a better grade bolt or stud and have them all replaced with proper torque procedures done. Having large pieces of metal free floating in with the valve train on a running engine is not gonna fare well for that engine. It didn't do to well once for you let alone 29 more times. I wouldn't be able to sleep at night till i ensured I had something I trusted under the valve cover.
