I took the thermostat housing off again, gave both surfaces a clean and used some fresh rtv, wasn't 100% that it wasn't running down from the back of the housing, likely from one of the scews. I have also used rtv on the flange rather than a paper gasket. No longer leaking although I now seem to have sprung a leak from my rad, 1 step forward and 2 back atm.
One other thing is i'm getting a hard start from cold, once it has warmed up it is fine. I'm getting a glowplug relay malfunction present fault in opcom. It that likely to be my problem even though it is 19c outside? where is the relay on these and is their a fuse for the plugs?

The exact fault code is P0380 - (2) Glow Time Relay Circuit Malfunction - Not present
I have fixed my leak, fitted a new rad after fitting one from the scrap yard that also leaked. Apart from the glowplug issue the other code i'm getting is P0602 - ( A ) Small Injection Quantity not Learned - Present, for some reason the injectors were programmed with different codes than the one printed on the plug, I have used the ones on the plug and get that fault although it could be related to the below issue.
I have to crank it for a few seconds before it fires up and then it will start ok the rest of the day, idle seems a bit rough and I'm sure I have a knock, also noticed some white smoke when reversing and the exhaust fumes smell strong. Just wondering if a piece of o ring may have gone down the leak off pipe hole on the top of an injector, the old leak off pipes were brittle and broke when removing them. I had to use a small screwdrive to get one out of the end of one of the injectors.

I did see that listing on eBay but it dosn't come with a 3 way tee, so I ended up buying a complete one https://www.ebay.co.uk/itm/GENUINE-VAUXHALL-MERIVA...
Can't help but think some debris may be in one of the injectors, might take the tops off and see if I can spray something down to check and refit, not sure if that will work and if it worth running some cleaner through too aftert. I have ordered 4 new bosch glow plugs £30, seems a bit cheap but seller looks genuine https://www.ebay.co.uk/itm/GLP092-BOSCH-GLOW-PLUG-... The numbers are clearly printed on the injector plugs, so no idea why different codes were entered.

Just relized the number in the error code refers to which cylinder the plug is in, for some reason no 4 dosn't click on like the rest. Anyway that's the least of my problems, think I am ready to give up on this van. Tryed to get the glowplugs out being very gentle, they started to turn but the nuts have broken on 2, managed to replace the other 2 but now need a way to remove the broken 2 because i'm not removing the head.
They only turned a bit so engine still starts with no loss of compression, also alternator issue again, noticed it was making a noise so checked when got back home and it was smoking again, seems to have stopped now. It was replaced with one from the scrappy 2 weeks ago because of the same issue, no idea if it is just coincidence that another one is likely to fail or if something else is causing it. If that goes I think I will just give up, shame because the engine has only done just over 60k.

To be honest i'm suspicious of the mileage, I left the plugs in when I removed the head, should of really removed and replaced them then. It seems to be very common for them to break just below the hex nut on these vans from looking around. The nut and electrode are still on but the nut just spins, there isn't a lot of room to try and grip anything.
I might see if I can remove the nut and electrode and see if I can hammer a torx socket in. The alternator I got from the scrappy was pretty dirty, clogged up with old oil by the looks of it but I was pretty stuck and that was all they had in.
