Today was looking like a good day. I pulled the K301AS from my CC122. Everything was going quite well until I got to this:
It looks like this engine has thrown a rod somewhere in the past. There were no chunks or pieces found, so they cleaned it up fairly well.
Can I use this block, or should I start looking for a new one? I'd hoped to do a simple full rebuild with a new piston and rod, but now I'm not so sure. The piston had an "A" on top - is that factory size, not overbored yet? The piston is pretty pathetic, it has what looks like carbon scrapes above the first compression ring. The oil ring and the 2nd compression ring had the gaps lined up, which probably wasn't good. Probably didn't matter though, this thing was pumping oil like mad.
Please, someone, tell me that you've seen worse and had a successful rebuild? Please?
Man, this sucks...
Thanks,
Jim
