Hi, my engine overheated after the coolant hoses burst. It seems that the system was pressurised. Not sure why yet. It did start up again but took a lot of turning over and pumping the throttle. It won't start at all now, so I slackened the injector pipe, but hardly any diesel came out when cranking. I took the pipe off from the pump and just a small squirt of fuel comes out. Is this normal, I expected a high pressure squirt, but I don't really know much about diesel engines. I did take a short video but can't upload it until I open a photobucket account.

Did you press the accelerator right down while you were cranking and observing? Obviously not much fuel will be pumped if you don't.

Ah! No, I just turned the key. Would that increase the pressure. The spurt of fuel that came out didn't seem to have much pressure behind it, I was expecting it to really shoot out, but I haven't really worked on diesels before, so wasn't sure what to expect. 
I'll give it a try again tomorrow.

The amount of fuel that comes out depends on how much you press the accelerator . Even then don't expect a flood of fuel. It's only a small engine!

You will get a few drops of fuel at each injector pipe every two revs of the engine.

Oh dear. I tried turning the engine over with throttle depressed, but it was much the same. A spurt of fuel each revolution. I didn't have a 27mm injector socket, but managed to get no 4 injector out with a ring spanner. It was light most of the way, possibly due to the overheating. I connected it to the fuel line and it sprayed okay, I think, as I have no experience to compare. So that was my hopeful, easy option gone. 
I checked the compression cold, as I can't run it to warm it up. The Wiki said commpression warm should be 28-34 bar, with a min of 11 bar. I was getting 15 bar, so moderately happy. 
The injector socket arrived yesterday and I removed the other 3. No 1 was 18 bar, no 2 was 6 bar and no 3 was 5 bar. Not so happy now. 
So, now committed to the engine coming out. I was considering engine swaps, but I don't want the van off the road while I gather an engine and any parts I need. Does anyone know parts availability for the CS engine, and prices for head work etc. It's been a long time since I have had any engine machining done. I don;t imagine there are as many machine shops around now.

Hi, I've put in my other post. The compressions are,
Dry      No 1 - 16b   No 2 - 10b   No 3 - 6b   No 4 - 19b
Wet    No 1 - 38b   No 2 - 36b   No 3 - 35b   No 4 - 38b

So would look like a ring problem. Still tentatively looking at other engines, but IY engines seem pretty scarce. Are there any other N/A diesel  engines that are an easy swap.
