Hi guys
So I've stripped my engine back to the crankcase, cleaned everything,  replaced all the gaskets and fitted new injectors but the thing is still overheating for some reason. It had also had new oil, fuel, air filters and fresh oil.
It starts and runs fine but then cuts out after about two hours.
Any clues?
Thanx for your time

Ok. So now I have had my injectors out, stripped, cleaned, and rebuilt my engine. I have bled the fuel lines in the usual way up to the nuts at the base of the Swan necked fuel lines but I still can't get the thing to start. There must be something I'm missing. Could anyone help me further? Thanx in advance.

Thanx. Is it possible to remove the injectors without having to remove the cylinder heads?

I checked the leak off pipes (which are copper in my case) and changed the copper washers but that does not seem to have been the problem. I'm guessing from your response that I must have the lucas type. I will see about removing them and checking the O rings. I will let you know how I get on. Thanx once again.
