I have a rb26dett and removed oem oil block. I installed a greddy sandwich plate, and now my oil pressure before my oil filter is as much as 140 psi. Way too much pressure for my liking. I would like to remove the blind plug blocking the bypass gallery and install a bypass valve. I wanted to know how people have gone about removing the plug. I was thinking about drilling into the plug and trying to twist/pull the plug out, but I have no idea how thick the plug is / if I'll have enough force to remove it since it's wedged in the block. My engine is in the car, so drilling maybe half way into the plug is my only option. Anyone who has any experience removing these blind plugs, your help would be much appreciated.
Thanks
