Firstly, I'm completely new to engine mechanics so not very knowledgable. I have a BMC 1.5 which started to produce lots of blue smoke some while ago. I suspected a head gasket problem but knew that the problem could also be caused by worn piston rings, worn bores etc. I removed the cylinder head and contacted a local engine rebuilding specialist who is highly experienced and was recommended to me by a narrowboat hire company - so I trust him. He came and checked the bores and said they were in good condition, showing very little wear but that he could see the gasket had gone between the second and third cylinders. He said he didn't think the engine was burning oil in the normally accepted sense but that he thinks oil must have been getting into the second and third bores where the gasket had gone and being blown out through the exhaust. I stripped the head down myself and he skimmed it and confirmed that it had been warped slightly. He fitted new valves, stem seals, etc I then refitted it - with a new head gasket and other bits that needed to be replaced which I got from Calcutt boats, using the workshop manual, various You Tube videos and making a nuisance of myself ringing various companies and asking questions. I then adjusted the valve clearances, bled the fuel system, checked the oil (just above the minimum marker because I've been told not to overfill). By some miracle, the engine started with very little difficulty and ran for about fifteen minutes when I noticed that oil was seeping out from the front end of the rocker box cover on the starboard side. I also couldn't help noticing that the engine is still producing blue smoke - which is a massive disappointment. So my questions are - is it likely that the oil leak is just due to me not getting the cork rocker cover gasket seated correctly? Is it possible that an excessive amount of oil is getting up into the rocker area causing it to leak out under or over the gasket? Is it possible that something is blocked and preventing oil from draining back down into the engine block? Could any of these possibilities result in the continuing production of blue smoke. Apart from the work on the head, I have done all the work myself and I know nothing! Is there anything that anyone can think of that a complete numpty may have done wrong that I could check. All suggestions will be most gratefully received.

Hello all. Recently the dual belts on my travelpower broke and after removing them I cruised the half an hour or so home to my mooring. The engine seemed fine without belts on the second alternator with no extra vibration and if anything seemed better due to the lack of the monster travelpower alternator. However. This was a very stupid thing to do. I took the boat out since then and all oil drained out. Well, sprayed out. Everywhere. I refilled with oil and replaced the filter. Tested the engine and still oil droplets. I suspect the leak is between the fly wheel and the engine. This has messed up the standard alternator too I fear as the tacho goes up to tick over but stays there no matter what the revs (checked all wiring). There seems to be a tiiiny bit of play on the flywheel and the gap between the fly wheel and the engine is ominously shiny (approx 4mm). Oil level is stable when the engine is off. How do I remedy this situation?

Hi folks. My Lister Lpws4 has a leaky low oil pressure sender. I think it must have been weeping for a while but I now think it is getting worse. The audible alarm stops when I start the engine, but I'm not sure if this alarm is also connected to the charge circuit. I don't appear to have a lighting up pressure warning light on the warning light panel. Before I change the sensor, I would like to find out what the 3 terminals are for. I am familiar with the single wire type connected on car's. 3 terminals seems two too many! Are they, + (feed), buzzer and light? As the unit is leaky, I guess it may be the cause of the warning lamp failure. On a car it would be a simple case of touching the sender +feed to earth, I fear if one of these wires is live, touching it to earth might blow something, as might connecting a live feed to one of the other terminals? I have no idea where I could get hold of a wiring diagram. Thanks in anticipation, Patrick.
