A brief bit of background.....
Bought a used motor with 58k miles. I thought....heh heh heh...I was getting a motor that was good enough to drop in and go. So did the seller, I guess. It turned out to be quite a different story. I'm going through the motor and doing a freshen-up: rings, bearings, oil pump, timing chain, valve grind, etc. but no machine work to speak of. Anyhow......
Have you ever put togther a motor and worried because things were going too well? That's where I'm at with this "freshen up" project.
There is virtually no cylinder wear. Piston-to-wall clearance is right at .004" for all slugs. All my rings are fine with end gaps spot-on....not a single mis-packaged ring in the bunch. All there bearing clearances are at .002" except the rear main at 0025". Conn rod side clearance is fine on all six, even with the one rod coming from a different motor. The crank is fine....no damage despite several bearings showing some copper....caught it just in the nick of time.
The entire reciproacting assembly is done and I can't remember having one go together so easily.
Had a valve job done and the machine shop reported everywas was "A-OK"....no cracks, no burned valves, no nothin'.
So far the only glitch, besides being waaaay over budget, was that bent rod....no doubt a hydro-locked piston due to the blown head gasket. Maybe that's the bit of trouble I've been looking for and I've already gone through it?
Well, sorry for the ramble.....I'm just trying to play reverse psychology with the fates. If I don't worry, something bad will happen. If I do worry, everything will be OK
Thanks for listening
