There is nothing directly pointing to why the blowby suddenly increased. Pistons, rings, liners, head gasket and head and valves all look generally OK. May have been a stuck ring. I'm replacing all the noted parts and the crank bearings so hopefully all should be OK for the next 30 years. Maybe I should replace some of my parts to just keep up...

If you don't mind me asking, who is doing the work on the engine? And also, just curious, how do you think this happened "one of the pistons looked as though some water may have got in and possibly seized a ring"? Bob Abbott AZURA C&C 32 - 84 Halifax, N.S.

After a bit of thought and asking a few questions, I bought a low-hour used Yanmar 3GM30 thinking it would be an easy install. Turned out to be very difficult to locate parts to mate it to my Hurth V-drive transmission and I eventually gave that idea up and put the engine in my storage space. After a couple of days of work, I dissembled all the surrounding woodwork and weaseled the engine out from under the cockpit sole into the aft cabin, an interesting exercise to say the least. I think they suspended the engine in mid-air and built the boat around it. I removed the carcass with the club jib crane and lugged it off to the local engine rebuilding experts. They tore it down to see what caused the blow-by which had caused the problem. There was nothing obvious at all to be seen other than one of the pistons looked as though some water may have got in and possibly seized a ring. They magnafluxed the head and all is good. Also, surprisingly, the interior of the block is a clean as a whistle with no corrosion or deposits of note. Pretty good for a raw-water cooled engine. We decided to replace the cylinder liners, pistons and rings, crank bearings, exhaust valves, thermostats and motor mounts. Everything is available in NA except the head and pan gaskets which are on the way from Japan. Total rebuild cost will be around $3,500. Maybe.. While I'm awaiting the parts, I've been cleaning the bilge and swamping out the engine room. I've stripped out a bunch of previously inaccessible old wiring and plumbing too and am replacing anything that looks suspicious. Lots of dirty fun. If anyone needs it, I have a perfectly good low-hour Yanmar 3GM30 for sale. I have $4,800 in it and that's what I'm asking. More to come as the best summer in years slowly disappears.
