I expected much worse. After the thread about the short balance shaft snub failing due to lack of support from the shortened balance shaft, I got worried. After three years of use I thought that I'd be cautious and tear the motor down, expecting to have to do at least the bearings, rings and a re-hone.
I used heavy Mobil 1 oil the whole time.
Here are some pics-
Oil Pump Shafts- zero scoring.
Rod bearings- no flattening but a little wear, no gouges or scratches at all but some shiny spots here and there..
Main bearings- look very good as well. Very clean, no gouges or scoring.
Oil pump face-
A little scoring here. It's going to be replaced. Engine front cover has zero scoring. I'll reuse that.
Piston skirts look great, no scuffing. No signs of detonation on the top.
I'm going to send everything to the machine shop and have them magniflux the crank, rehone, measure the big rod ends and magniflux the rods. I'm very happy with the way it's held up. Maybe I got lucky.
