Started it and it jumped straight to 4.5bar with a lot of lifter noise, ran it for a couple of minutes to see if they pumped up but no change so we stopped.
Ended up pulling the cam cover off and theres no oil in the head at all, confirmed the check valve is in and the vertical oil passage from the block is clear.

What next? Fill the head oil passages, reinstall the check valve and try again?

I cant think of anything else it could be apart from the main oil passage being blocked and I would have thought we would have excessive oil pressure if that was the case.

Start the engine with the valve cover removed to see if you have oil coming out of the passage.
Remove the check valve to make sure you get oil to the top.

Then check the check-valve; mine was rusted solid after having been in the engine for a long time.. New ones are pricey though.....

Thanks Bas, Ill give that a go tomorrow, we did pump oil in through the filter housing before we turned it over so I would have thought at least some would have made it to the head but maybe there wasnt enough pressure.

I do have a spare check valve, I bought it by accident not realising my head already had one. I dont think it was seized though, it came out pretty easily.
