Does anyone know what size the plug bolt is on the oil pressure test port? In case you didn't know, it's the bolt below the oil filter. I wanted to test my oil pressure and hook up an oil temp sensor. I bought an oil pressure tester that came with a variety of adapters. The M14x1.5 adapter was the closest to the plug. However it appears that the threads on this plug are not tapered and are of a finer thread pitch. Or maybe I should ask if anyone knows where I can get an adapter for the test port to a 1/8" NPT fitting?
