Well as long as it just the calorifier / heat exchanger thing-gumy-jig ok.
It's when you get head gasket symptoms and it's not the head gasket it becomes an anchor.
God I hope it's not a MD3 or some such.
The cylinder sleeves are seperate, the joints at the bottom die, anchor time...

If you think about the design the O ring is not doing what O rings should, either a tight fit between the casting and the neck, seems very unlikely, or where it appears to be but no pressure to hold it down to seal
So it is really not doing anything, better to bed the neck on your gunge of choice

Hi Mat,
luckily it’s an MD2030, with about 1500 hrs on it. Has been very reliable for the last 12 years, touch wood. Mind you I do TRY and look after it. Biggest problem is the high rise exhaust elbow, which keeps rusting up which is a common problem. They are no longer available and if you do find one they are upwards of £800 I've tried various things to try and keep the casting clear. I've now resorted to electrolysis which seemed to work really well last year when I tried it for the first time, so we'll see how it perfoms this season.

Been down this route and I can’t use an off the shelf stainless one. I have to have the high rise unit as my engine exhaust is slightly below the water line. The high rise gives another 30cm of lift so that there is no possibility of syphoning of sea water from the external exhaust outlet into the engine.Volvo Penta MD2030 Stainless Steel Exhaust Outlet Kit

Gotcha, that’s the issue with marine stuff, unless you know the exact utilisation each can be different even between boat production runs.Been down this route and I can’t use an off the shelf stainless one.

do you have space to incorporate a U loop into the exhaust system to prevent siphoning?

interestingly there is a large one which loops up inside a cupboard, I've been meaning to investigate the installation starting with the Volvo Penta installation manual just in case it’s was a ‘belt and braces’ thing by the builder but they built 65 of this model and they all have high rise, it’s on the long list I,ve just had so many other things to sort out with a higher priority, like using it rather than working on it….! but that’s boats

Was it you that asked about Marine wet exhausts to BS xxxxx ?
Here's what we use.
Lloyds is better than BS my boss says. 45 or 55 mm available.

I think it was me but it was for 45mm fuel pipe. I found some that will do the job
