#138354, "What does this bolt on the backside of my engine do?" May-01-14 12:33 AM by Th3DooM
A week ago I checked a couple of things on the car. When I looked under the engine I noticed a bolt between knock sensor and freeze plug that I hadn't heard of before. Can anyone tell me for what the hole was drilled and then closed? Would it be possible to install an oil pressure sensor there?
