ok, pulled the PCV and cleaned it not really a problem.

However the oil is flowing continually out of the relief valve into the tube directly above the fuel pump. Hence the problem. Broke the seal on the relief valve and checked it , all good. Turned it two extra turns, which stopped the flow but put the engine oil pressure up to 80 lbs!!!! Broke for lunch and a think. Back on it tommorrow. Maybe the oil cooler is plumbed incorrectly and restricting the flow??/

Edit; there are two fleible pipe that then join onto the steel pipes upto the cooler. If I was half asleep when I assembled it I may have crossed these, but I would think I have checked this was correct at the time. More confusing is the T16 manual which shows the relief valve on the side of the crankcase opposite to mine. In other words, it may be that good old British Army have assembled my engine with the relief valve on the return pipe not the outlet pipe.....Not sure what effect this would have until I can sit down and think about it. so to be clear, my valve assembly is on the pipe on the clutch housing/crankcase nearest the outside of the engine, whereas in the book it appears to be on the union nearest the middle of the engine......Would it matter?? Must do surely
