have you tried to find pattern Mitsubishi parts instead of OEM's ? I haven't rebuilt an engine for many years but I remember then a humungus price difference between OEM pistons/rings and pattern ones. I'm well out of touch but are people like Hepolite still running ? maybe one of the more up to date amongst us will know

See if TW Marine would be happy to rip your engine open and find the fault and do it up all nicely again. You just need a tow there - easypeasy with no locks on the Maccy (OK, 12 at Bosley). They are canalside. Then you'll know your engine will go for another 30 years.

Will that BMC 1.5 Peter has fit in it? Actually if a BMC 1.5 will fit we could attack stabby's mooring in the dead of night and get his spare. Mind you if he hears us, the knife'll be out Rog

Mind you if he hears us, the knife'll be out Rog I've messaged Peter about that engine. I don't see why it shouldn't fit, I have a cruiser deck, reasonable amount of room. Whether it can be adapted economically though is another matter!

Unfortunately though, I neither have the amount of money this would cost nor the ability to move the boat 40 miles/ 35 locks!

Whether it can be adapted economically though is another matter! We considered a new engine 2.5 years ago but all the re-shaping of the steelwork the engine sits on would have been, what, £1000? A new engine these days, built of cheap components - that or our chunky old solid mass of Made-in-Denmark engine ripped to pieces and built up again with new bearings? We have the old engine, and will just have to see how it behaves - I listen carefully to it, and keep it happy purring in a stream of new, clear, golden oil.

Borrow an outboard motor to get to TW? Thunderboaters willing to help toward the cost? What IS wrong with the engine anyway? Have I missed that bit?

By the way, as this thread be about engines: I want to drain the coolant from our engine, to change it, and so I can inspect the water pump impeller. What is a good quality anti-freeze? The green stuff (not pink), ordinary ethylene glycol. Are there better brands? And from where to find it?

Apologies in advance for the technical engineering language but it would appear to me to be a case of "the fekkin fekker's fekkin fekked"

Borrow an outboard motor to get to TW? Thunderboaters willing to help toward the cost? What IS wrong with the engine anyway? Have I missed that bit? Don't know what's wrong with it at the moment, Tony Dunkley is coming over to find out at some stage. Basically: it won't start. All air has been purged from the system, twice. It doesn't get close to starting, even with the use of the evil easy start. I've had the rocker cover off. The valves etc. appear to be working as they should, from a quick look. The clearances are too big, definitely need adjusting but this on its own shouldn't prevent the engine starting. The thinking from this is that it could be a couple of things: 1/ A very badly blown head gasket 2/ Loss of ignition timing. There's no belt or chain, the drive is from gears. If the engine was rebuilt badly, maybe a key was left out or something it could have either slipped or destroyed itself. Also, when I turn it over with the rocker cover removed there are fumes exiting from one of the push rod shafts. Seal maybe? There's also a fair build up of carbon around the back of the engine (opposite end to the gearbox), maybe this ties in with a blown gasket, I don't know. There's also a fair build up of carbon inside the air intake, there's no filter on this model. Before the breakdown the engine ran OK, I think. I never thought it had much power but there again it's only 11hp. The only noticeable things were black smoke (not huge amounts) if I ran the engine at full throttle. Also some black smoke when the engine was on idle. The idle was set too low, fixing this was on the to do list. No smoke at all when the engine ran above idle, but below full throttle. That's all I know at the moment!

Have owners of the same engine model experienced the same? Have you written to Vetus/Vetus experts? Anyone where you are capable of pulling it all to bits and putting it back together? It's only a couple of hours' work if you really know what you're doing. I've seen them make engines at Ford in Dagenham!

I really sympathise.
Fortunately my engine woes give me time to consider what to do, as the current one works normally, apart from blowing oil out of the exhaust.
Spending what could be thousands of pounds on a bog standard Japanese engine, which is 24 years old anyway, or put those thousands to a new engine.
As a point of interest I once chatted to a guy who had a National engine, built in 1939 if I remember correctly, who ended up spending £22,000 on having it rebuilt. At least at the end of it he had a National, which people will pay silly money for.
At the moment I'm favouring a new engine. It will hopefully see my boating days out.
I am very fortunate. I don't really want to spend 6k, but I can afford to.

It's only a couple of hours' work if you really know what you're doing. I've seen them make engines at Ford in Dagenham! When we shared Copperkins, the Vetus 4.14 failed to start one morning. It was relatively soon after the engine had been reconditioned (at Ownerships' insistence; they had a thing about engines more than 6 years old at the time). Nothing worked; we ran the starter battery flat, as well as a jump start pack, while checking fuel, heater plugs, etc, trying Easystart, sacrificing a few chickens, and anything else we could think of. Ended up getting towed back to boatyard. Cause was stuck piston rings, blamed by the yard on the engine having been overheated, but all four pistons, all piston rings, and no other signs of overheating? Each ring was a press fit in its groove. I have always put this down to poor re-build, as it transpired that the block, despite having turned from Vetus yellow to Mitsubishi blue, was our original one, and not a replacement short engine. Maybe Ricco's motor was rebuilt by the same guys? We we actually did quite well out of the incident; we got a new engine, at Ownerships' expense. (It's still going strong)

I don't understand what the block being the old/original one has to do with this. We have our old/original 'block' - piston and liner replaced.
Were your rings really 'stuck'?
Thinking this morning about ricco's engine, I'm guessing not having a running engine means no hot water, and that the batteries must be getting flat. Solar panel helps how much all on its own?
