Question

I was driving about 60 mph and lost power. Before I could shut off the engine I could here a slight knocking noise.   After checking I found a EUP broke . Truck is at Mack dealership now.  Will this ruin the cam ?  The dealership has had it two days and say they are diagnose the problem.  2002 RD688S. E7 350 hp.  What do you guys recommend for repairs. Truck has 125k miles but 14,000 hours . Should I do in frame rebuild or just fix what is broken ?  Please help me.

It all depends on the extent of the damage! usually the cam and the cam followers are replaced!
