I think I may have asked this question a couple years back but I don't think the question was ever answered. Back in 1972, I was having problems with my oil pressure and instead of going through systematically and trying to find what the actual problem was (main bearings, oil pump, etc.) someone told me about a modification that had been done on some race engines of that era to increase oil flow where they had plugged the bypass valve and just made sure they changed the filter element more frequently. I don't want to bore you with my story but the engine has not been started since.
I did the modification back in 72 but am now in the process of restoration and am having second thoughts about weather I plugged the wrong oil passage. In the two photos shown you can see what I did by drilling out the oil passage that had the bypass (ball) valve in it, threaded the passageway and screwed a large setscrew into the passageway that used to house the bypass valve that was supposed to let oil circulate even though the oil filter may be completely full of contaminants and not letting enough oil flow through the filter. I really don't want to look for another filter housing. If anyone out there has any advice for me or affirmation that I didn't totally screw it up, I would be appreciative. Jaco
