Great running engine with 12K miles started to make random knocking noise at low RPM's. Pulled timing gear cover, gear is tight no tooth issues. Pulled pan and found chunks of babbit in pan. Found 2 connecting rod journals missing side pieces of babbit. Rod ends have excessive lateral movement. Decided to replace all connecting rods with new insert bearing type.
Question: Working from the underside of the engine, can the connecting rods be removed without removing the pistons? It looks like the pistons can be lowered down enough to expose the wrist pin for removal. Am I dreaming?
