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?  |

Here's a picture of one I just took off an engine I am going to rebuild. The top is about 1/16 to 1/8 inch from the top. This engine was in unknown state as I started to take it apart. It wouldn't turn, intake manifold was off and very dirty and oily. After removing the head found three cylinders with what looked like cat litter/coarse sand mixed in them. I doubt the engine would have done anything if I decided to try and start it. Art Attachment: DCP_0014[1].JPG (Downloaded 59 times) |

Thanks art but the visible part of your valve will always be in the same place as it is held by the pin. I need to know the dimension to the sleeve which is inside and not locked into position. |

I need to get a small pin drift to get the pin out to check. Nothing here small enough to work. |

I measured the cylinder in place and found it to be .25 (1/4) inch from the face. I checked another assembly and it measured the same distance. |
