 The 907 in my JH-5 is building up so much oil pressure it is blowing out the gasket on oil filters.

Took off the oil pump assembly and the sleeve on the bypass valve has moved so that it will not allow any oil through the hole.

From the distributor side the sleeve is now .85 inches from the face. Does anyone have an assembly handy that could tell me what the proper placement should be?
