Narrowboat Nimrod

They also had ridge dodger rings, they had a step cut in the top edge of the new top ring so it would avoid the step at the top of the bore made by the sweep of the original ring. Real rough stuff but back then money was tight, unlike the bores.

Remove and back flush it with a hose, just use your hand to make a seal and run the water in the opposite direction to normal flow. If you run it into a bucket you can see what washes out. If you can see the individual tubes you could poke a pipe cleaner down them to make sure they are clear. Do not use wire ect as you could damage the tubes. Good luck.

I have read post 20 it refers to the RCD, not relevant to my post or the OPs boat. Hows the weather in Brussels?

I am not seeing the post in which I claim to have read them? In my original post I offered the OP best wishes and support in his project and said the regulations were not that onerous. This thread is about his boat, an old boat. You pair of clowns have decided to round on me waving your RCD paperwork and quoting rules and regulations that bear no relation to the thread. You don't live in Brussels by any chance?

If you could quote the bit where I inferred I had read the RCD that would be great.

As stated above my post predated your RCD/OCD bullshit fest. You chose to presume you know what I meant, your mistake. 5759 and counting.

You should note my original post predated all the RCD bullshit being discussed. And that is the post you chose to comment on.

BSS boat safety scheme. BSC? BSSC? IDFK?? And another one! The boat in question is not new, it is not subject to RCD requirements. It will require BSS which is available online.

The boat in question is not new, the post is not about a new boat so RCD has nothing to do with this post. I would have thought for someone who wastes their entire life on here you would have known that? (Post count noted).

Good luck with your project, it already sounds like you have the skills and know enough people to make a judgment on the viability of the boat. The regs are all online and not a complicated as some people would like to think. Its a canal boat at the end of the day, not the space shuttle.

A head gasket ring blown between two cylinders will allow an engine to crank , all the valves ect move as usual but it will not start, the compression just passes from one cylinder to the next. It would be unlucky for all three cylinders to be involved but not impossible. Test for such faults or valve faults by placing flat fingers over the intake and feeling for suction when cranking. Do not use your palm or other body parts cover it unless you want a hard to explain love bite.

If you have any doubt about the flexi hoses swap them out for rigid plastic plumbing waste pipe if possible. We did ours a couple of years ago and it is a good upgrade. Plus another vote for the bio washing powder, the aldi one is cheap and works well.

On the top of the calorifier there should be a pressure relief valve like a black plastic knob, usually they twist and you can bleed any air out of there.

Have you bled the calorifier? Air trapped here or in any part of the system will Cause the pump to run longer. Might be worth checking.
