My39 Six issues started when I diagnosed it as a bad wrist pin on cylinder #3. I was close, bad wrist pin bearing (almost worn thru) and as I progressed to look at bearings, found # 5 top ring shattered in 7 pieces and #6 in 3 pieces. Long story short, had engine completely rebuilt, crank reground, cam reground, cylinders rebored everything else is new, pistons, rings, guides and valves from Egge, not sure where rebuilder bought chain and bushings but certain it is top notch as builder is very reputable in this area. When I fired her up a couple of weeks ago, couldn't be happier with sound and knowing that in my lifetime the engine will last and be passed onto my kids.

My advice, do it once and rest knowing that the engine will last your lifetime
