    In Stouts post I think I broke my engine, garage gnome relied about melling oil pumps breaking.

    "Be leery of the new oil pumps. On the 2A page, 3 members including myself have had them seize up and break cam and oil pump gear teeth. I was lucky and the only the oil pump teeth broke. If I were you, I would rebuild the original oil pump if you still have it and put that in and see what happens. Is the new pump a melling? Those are the ones we were have the issues with. We did prime them correctly. For whatever reason they lock up. That would be where I would start investigating."

    Does anyone know where or who makes a good rebuild kit for the oil pump on our 134 f head? mine is in need of a rebuild. and can't find a kit anywhere.

    My engine rebuild kit came with the gaskets and stuff to do it. That was 5 years ago and I do not recall the kit manufacturer. I didn't come with new gears though. I reused the old ones and I have great oil pressure at a cold idle of 40psi, 20 when hot.

    That's the exact oil pressure I get.
