I had a phone call from Gary at Heyford Fields Boatyard. Our engine is out of TQ and is in pieces. We're having the crankshaft re-manufactured, at least the bit on the front end where the pulleys fit. While the engine is out, it's a good time to look for wear in the critical parts. Gary has advised we have new engine mountings, a drive plate, new big end shells, and new piston rings. It would be false economy not to do this, I fear the engine would be out again in twelve months time if we didn't.
The shells are showing signs of discolouration so they're down to their limit, and the rings are slightly grooved, as are the bores. Gary will lightly hone the bores to remove any high spots before fitting the pistons with new rings. It's impossible to fit the old rings back in exactly the same place and if they were fitted, the engine would lose compression, burn oil and have a smoky exhaust.
