Who replaced the rod? Do you have XENTRY?

its extremely unlikely when you bend a rod that you didn't trash the block (and the crank won't like it either)

AMG motors its normal to snag a rod and trash the engine (its a design feature), animals out there do a cast iron liner mod, that real animals do on one pot only - then clear the car quick smart

what bent the rod nasty map and ragging a stone cold engine (that's the usual driver) or leaking injectors etc.?

I had a mechanic do it
took 2 months little by little

no I don’t have XENTRY
I will look but where can I get a XENTRY?
thx

What caused the rod failure?

Water coming in from front intake to manifold

Well at least the radio works.

You need XENTRY, or at least your mechanic does. If the mechanic reassembled the engine, can't get it to start, and doesn't have XENTRY, it's probably time to find a new mechanic.
