gtomo2:
Anybody know if i undo the bolts at the bottom of the oil pump above were the filter goes will it release the pump.

gtomo2:
ok undid the bolts and the lower half of the pump came off. found the oil pressure relief valve was stuck in the tube and took a lot to move it. When it did come out fouind scoring on the valve and in the housing for it cleaned it up and pushed it back in using the spring removed the spring and the valve was stuck tight again so think this is the problem. When i turn the engine by hand the gears turn ok. So could i be right in thinking the relief valve is kapput

Its a bit Late

But my V8 oil pump had to be packed with vasaline to prime it ......It may be the case that after changing the filter it may need re priming

A stuck PRV would cause the probelms you are having.  Did you use an oil flush at all?

gtomo2:
No but did use a oil aditive in the oil, put it in about a week ago. Will try some wet and dry on the valve and surround and see if that frees it up a bit.
