Oil Pump Shim

[supraguy31]

Ok all, When my engine was Built, The builder installed a 1" Bolt in the oil pump. I guess he was thinking that the engine needed more oil Pressure, Basically now, when I rev the motor up to about 3000-3500rpms, The oil filter O-ring blows off the filter and oil goes everywhere. I forget to mention that the oil Pressure gauge almost Pegs out.

Have any of you ever shimmed the oil pump and if so, What degree did you use. When I remove it, Should I go with a Smaller shim or no shim at all?

heh, there are a few threads going on about this right now. i think it's been decided that 1" is too much. roughly 5mm of washers *should* do the trick. check out the reference section
