  1. Hi we have a ruston Hornsby 2YD in our narrowboat. One of the cylinders is blowing around the joint so suspect head gasket leak . Apart from blowing from the joint she is running ok and starting ok no oil in water etc. I am under the impression from the manual the head and block has a copper ring and no such head gasket. Has anyone had any experience of such engines and is it a straight forward job to fix. Thanks in advance Michael.
  2. Thanks certainly will if I go down that route.
  3. Yes but they have changed engines since ours was made. And the place in Southampton advanced yacht systems only have new ones for the modern engine at around £400. Sometimes they get second hand parts in for the older engine. So I could give them a ring you never know. Thanks
  4. Many thanks for all your replays. I am trying to upload pictures but without success (Looks like I will have to wait for the grandson again 😁). Yes it's in a copper pipe shield this doesn't look factory to me as it's just standard copper pipe so may have been previously repaired by first owner me been the third. Unfortunately their is little room to strengthen the area that leeks as it's very tight against the casing. I will give advanced yacht systems a ring. Cheers for your answers much appreciated.
  5. Hi please can anyone help. We have a paguro 4000 cocoond built in generator in our narrowboat which has developed another water leak this I have traced to the exhaust manifold area which has a water jacket rapped around the manifold down pipe. This again has cracked on one of the joints and leaking antifreeze. I keep getting it soldered up but the vibrations set it off again. I was wondering what purpose it serves and could I bypass it. Water comes in at the top and excites and the bottom so maybe I could just use a pipe to join them together. The water comes from a skin tank which it shares with the main boat engine so is cooled that way. It was mentioned it could be an out let to heat water for the boat. Please has anyone got any ideas. Michael.
  6. Thanks slim for all your advice, ours is an older 4000 so properly will have this jacket you mentioned. So i will investigate this first. Many thank
  7. Many thanks Slim . I only replaced the rubber pipes so yes looks like you are right it could be the plastic elbow or somewhere in the alternator itself. Looks like a strip down. It could explain why when i turn the generator off the water/antifreeze in the tray under the generator that's leaked out is cold as though its been cooled by the alternator itself. This has really puzzled me as you would expect it to be warm if not hot when the rest of the system is. I have even felt the drips under the cocoon base these drips where cold and they had just left the generator. Mike.
  8. Thanks for all your comments i have previously had the gen out and as slim says its a pain to try and fine a leak. Thanks slim looks like your picture highlights the oil cooler i was wondering what that was, its the only part i didn't remove on the water side (but did replace hose as in picture underneath). So looks like i may have a leak in this area. As springy suggested i had tried with cap off the header tank and yes it does reduce but does not stop . Mike.
  9. Hi Tony no seems to be underneath cannot see where from . i have to mop out from the tray under the generator about a mug full then i have to top engine header up likewise.
  10. Hi David thanks for your reply. The generator is cooled by the skin tank (keel cooled) as is the engine. every time gen set is used i have to top up the engine header tank because of the leak. Not sure about the exhaust sorry not a mechanic but there is a water hose which enters the manifold of the engine just before exhaust joins so i presume there must be some water around this area. Mike.
  11. Hi we have a paguro 4000 generator in our narrowboat this is an Italian cocooned set which uses the one cylinder diesel engine i think its a ferrymann engine. This has remote stop start etc and uses the same keel cooled tank as our vintage engine. and has a wet exhaust what ever that means. The problem is it has a water leak which i cannot fine i have had the unit so far out (its very heavy) and replaced all water pipes i can see including water pump but still it leaks Its very hard to see once its in due to the coccoon case. but leaks around a mug full in 20mins use. into luckily a tray . What i cannot work out this water/ Antifreze is cold after its leaked out after its been run, yet all the pipes are hot. The leak seems to be coming from the generator end and only leaks when the set is running with a slight leak when not. Has anyone had any experience with these sets and had problems ,they where very expensive in there day and are still produced today but use a modern engine. many thanks in advance. Mike.
