Hello rebuilders. My M130.923 engine is fully disassembled and I need to replace torque bolts for the crankcase pan, manifold bolts, and perhaps a few others. My issue seems to be finding a single source that specializes in metric sizes for Mercedes.

A few questions: Does anyone know which engine bolts are single use torque and must be replaced?

Would replacing torque bolts with studs present a problem? (manifold)

Is anyone familiar with ARP kits? Why don't they have them for Mercedes? They have just about every other car.. including foreign metric engines.

I'm positive these get replaced all the time during engine rebuilds... but I can't find replacements!!
