I've had two catastrophic crank failures in my 1995 K 3500 within 100,000. I owned a 6.2 in an 85 K 1500 that went on and on but finally gave up due to starter bolts failure cracking off the block. Found 1984 6.2 engine in a Winnebago 95,000 actual. The engine so cleans it doesn't even have usual oil residue under air cleaner. I am a professional diesel mech and have rebuilt ebuilt several 6.5 and 6.2's. plan on at least putting new rod and mains with H/V oil pump and using 6.5 parts on the engine. Any recommendations? I am 60 and just plain tired of changing engines.
