So I've had piston/head off.....all good. No noticeable play on rod in different positions (slight sideways movement). Moderate bearing-type noise when rotating with pedal......with piston/head re-installed there is much more noise and quite hard to turn over.
So I guess all the main bearings are shot ? A complete new set is 42 euros but I'm not sure/confident about taking engine apart really with my limited skills/tools. Or is this relatively straight-forward ? Any suggestions appreciated.
