Matt,

I've got the 755 and 70 operator manuals. Contact me offline at flier@sbcglobal.net if you haven't gotten 'em yet.

Rings wouldn't be a big deal. I'd probably go ahead and do the rod bearings while I was at it. A scored piston wouldn't even be that big of a deal either. A scored cylinder would be a big deal as well as if I got into it and found out it needed a bunch of other stuff like mains, crank work, valve job, etc, etc. I was mainly interested to find out others experience with the durability of the Yanmar diesel in terms of the # of hrs before they typically require a top-end, just rings, boring, etc. As I said above, it runs good, develops good power, and doesn't smoke -- just some blowing smoke out the breather. I guess I need to just break down and do a compression test and a pressure check to see if I'm loosing air past the rings. At least that would narrow things down. OR, I could just run it 'till it has a real problem like using oil....

Thanks
