[Public-List] Replace/rebuild engine

[Anders Bro via Public-List]

If you lose oil, it isn't only the cylinder walls. You might want to check for scored main and connecting rod bearings. If the crank is scored, that can add quite a bit$. My experience with a largish 6 cyl Kubota tractor engine with a scored crank. It cost a bit over $1k to do a weld repair, and I think about double that (or more?) for a new one. (I pulled the crank, so the $1k does not include any mechanicing.)
