  1. Agreed. On an old worn 1.5 I would not be unduly worried if it got to above 40 psi hot and revving and around 12 psi on idle but it would suggest its time to start saving money for a major expense. The oil pressure switch if your engine has one works the oil pressure warning light and that is either on or off. Probably switches at around 12psi. What may give low oil pressure s the oil pressure relief valve stuck open but it shoudl never happen on a new engine or one few years old with regular oil changes. As you say, more bunkum. The overhaulers were probably too tight to fit a new oil pump or did not know how to measure the old one for wear. Otherwise the new main and big end bearings were not checked for clearance, nip, backing and butting/ With that low oil pressure I wonder if they even measured the bearing journals or had then reground. Make sure your friendly mechanic knows he will have to clamp or screw the compression tester into the engine and it must measure well in excess of 400 psi. (But probably not in your engine's case!)
  2. I think very likely but since put into the main bank.
  3. I found exactly the same on an EX BP boat right down to the snipped off cable. they were also using the relay studs as a junction box and one relay was redundant. I concluded that ether BP had converted to a twin alternator system of had re-engined with a twin alternator engine. I also wondered if they had a separate heating or fridge battery bank at one time but it was removed.
  4. No the this topic stays open indefinitely unless someone misbehaves or it goes badly off topic so the mods lock it The person equipped to do a compression test on a diesel (a petrol engine tester is no good) is very likely to have a mechanical oil pressure gauge so they can also check the actual oil pressure hot, cold, idle and revving. The oil pressureS MIGHT give a clue about bearing condition.
  5. I gather gas burners with too much air tend to roar and I have heard it on those frodges when rust flakes were in the burner.
  6. Thanks Heather, the anti-stall damper (call it what you will) was always a long shot so now that can be ruled out. I honestly fell you now need a compression test (and send us the results) plus a hot & cold oil pressure test at idle and at say 1000+ RPM. Also send the results. From those we can confirm that whatever the person doing the tests suggest sounds feasible. There are two places where washers may be on the top of the filter. The larger hexagon with the leak off pipe banjo on it normally has two soft washers one above and one below the banjo. A leak here is very annoying but should not affect performance. or starting to any significant extent. The other place there might be one s on the centre bolt that holds the whole assembly together. The problem is this is more often than not sealed by a rubber O ring, not a soft washer although some older engines may have used a soft washer here. In the past some after-market filters were supplied with O rings that were too small so leaked. Again as long as the lift pump (electric in your case) is pumping correctly I dunt a small leak here would cause any major problems.

  8. I would need to look at the full specifications to see exactly what the ssealer was but in general primers are porous so shoudl always be given top coat, even f you will rub it off next summer to complete the paint system. I was very happy with Johnstones professional oil based gloss on my boat.

  10. Agreed but I would do it when the burner was off for cleaning.
  11. Some time ago one of the mags had a piece about a chap who persuaded his mate, a farmer, to dig out a mooring on his land on the Tamar or tributary where the fellow proceeded to fit out his narrowboat. Getting it to the canals did involve sailing it to Plymouth, negotiations with the RN for access to a craning site. Maybe that mooring isavailable for a repeat.
  12. and while you are at it get or make a small long handles wire brush (one used to come with a new fridge) so you can remove the spiral from the flue and de-rust/de-carbon the flue tube.
  13. I too was interested in the answer to Matty's question because I felt the statement he queried was somewhat misleading to say the least. It seemed to imply that @Aegidian held a license/approval from CaRT to be a boat mover. I also felt he was trying to imply other boat users may not be so licensed. In other words typical marketeers near lies and distortion to gain an advantage. I think the sentence @matty40s should be rewritten so it says exactly what is offered along these lines: "I have CaRT trade plates so am able to move an unlicensed boat on CaRT waters.
