Explain more please? I suspect that you have hydro locked it with oil. In the meantime, drain the oil out. Take the injectors out, spin the engine over and blow any oil out that MAY have got in to the cylinders. Then reassemble and put the correct amount of oil in and see if that has fixed it.

You would have to put in a huge amount of extra oil to cause the underside of the pistons to lock up. In any event, I'm not sure that would lock in the piston rings or how one could possibly diagnose that without stripping the engine?
Suck/pump out the excess oil through the dipstick pipe using a small diameter tube and then try turning over the engine with a spanner on the crankshaft pulley. Once you've turned it over a few times, it should be fine.

he engine still turns over but will not start I've had injectors checked and are fine

Agreed but perhaps take out the glow plugs rather than disturb the injectors and the fuel pipes.???
OTOH It would be a good opportunity to get the injectors serviced

I have checked glow plugs and had injectors tested and where all working fine I put double the amount of oil needed I'm based in limehouse Marina London would you be interested trying to get engine working I've never had one problem before ??

My other concern would be battery does it have to have a lot of power to get started after 6 months not running

Thanks for information I purchased iana two years ago form an old gentleman called Ian he had owned for over 30 years I'm gutted it's not running it's been a real pleasure sailing

It will probably take a well charged battery to start it in this cooler weather but if it's spinning over well then the battery is OK.
Are you using the right starting procedure with the glow plugs? Someone with this engine would be the best person to comment.
If the starting procedure is correct then I would suspect that the fuel line needs bleeding. Personally, I would give Easy Start a go but others may advise against this and people with your engine will advise you how to bleed it correctly.
If you have taken out the excess engine oil, I doubt whether there is anything wrong with the engine. It just needs a bit of TLC.

Hi. A bit of unasked for advice given in a friendly way. Most lifeboat call out to sailing boats are for engine issues so the attitiude above is an accident waiting to happen. You owe it to yourself to get some basic understanding and this is your chance.
All diesel engines are the same in that they require three things to make them work - a supply of air, fuel njected into the cylinder, and sufficient compression when turned over to heat that air fuel mixture to the point where it explodes.
Lets take those three in turn. Its highly unlikely that you engine isnt getting air but check the air intake to make sure.
Now check if its getting fuel. If you have had the injector checked it will have been off the boat at a shed in all probability. Which means that it will have been disconnected and air will have got into the system. So follow the owners manual process for bleeding out the air and then finally turn the engine over with the injector connected but not installed. Keep clear of the fuel spray but check that you do get a spray.
Now put the injector back in the engine properly connected after quirting a bit of engine oil through the injector hole into the cylinder. A bit not a lot - its function is to make sure you have decent compression because your engine is old. . Use a well charged battery, let the glow plug hea for at least 5 secs and then turn over with decent throttle applied. And make sure your engine stop isnt activated.

A word of warning ... all the while you are trying to start it and failing to do so you will be pumping water through the heat exchanger into the exhaust system. If you flood the exhaust and it overflows back into the engine you will have some major problems
Therefore, while you are attempting to sort this out close the cooling water intake valve but be ready to open it again when the engine does eventually fire
( apologies if this has already been mentioned and I've missed it)

Good point Vic.
I'm sure that the fuel system just needs bleeding. I don't know whether that particular engine would self-bleed if it was given a quick burst of Easy Start (I do appreciate that you don't like that stuff) but I'll bet that it would fire for a few seconds, even if it didn't self bleed, which would confirm that air in the fuel line is the problem.

ITYWF that the injector leak off simply returns to the injector pump inlet so I guess it wont.Good point Vic.

If the system has not been bled since the injectors were re-installed then it will need bleeding before it will run but I assume they were removed and tested because it would not start.

Something strange here, first of all overfill with oil, piston rings are “locked in” What does that mean? Then wants help to start it, so it appears its turning over. When pushed says injectors have been checked. So some one with some knowledge has been messing with it? If someone has the knowledge to “check injectors” and pronounce on them, then I would expect that person to have the knowledge to bleed and start it?

Thanks for heads up I have learned to prim fuel pipes and checking glow plugs work I just not confident taking head apart to check pistons rings are ok I have a basic understanding but still learning many thanks

Yes it explains next to key
I've put battery on a slow charge ??

You will not be able to check the piston rings by removing the head or by taking it apart. Checking the rings is a much bigger job and, frankly, I don't think even removing the head is necessary. I don't know who is advising you but I'm afraid that they are not sufficiently experienced or knowledgeable to do so.
