Further to my last post where i mentioned my convert seemed to rev higher than what I considered normal, while updating my chain tensioner I removed the A.T.F. oil pump pressure relief valve for inspection & noticed that the spring appeared too short and with the valve assembled I could hear the ball rattling when I shook the cover, further measurements proved about a millimetre free play so obviously the pump could not reach specified pressure. The ball is 5/16 or 7.91mm and the spring is 1 5/32 or 29.26mm. Can some one help me with the correct spring and ball size as my searching has come up with nothing. Spring tension will have to be a calculated guess when replacing. Thanks
