It was 100 psi cold. something I tried thinking it would save on oil leaks. my oil filter used to seem to always leak a little. So I dropped the pan to inspect and all looked good. pickup is in nice and tight with no obstructions. It was sitting about 3/8" from the bottom of the pan so I adjusted down to 1/8".It's a Summit box type pickup. where would the best distance be for this pickup? I've read all sorts of different answers.
