After making the move to New Jersey last week from Virginia I noticed that my oil pressure was running high. It never does this, also there was a knocking that the engine was making. Two sure signs that I either need an oil pump, or a new timing belt. M y guess is that I need a new pump. I can't afford to take it in, and want to try this change out myself. Can anyone give me some inside info, advice, or tell me just what to expect if I try this myself, and maybe any special tools that I would need. Any and all help appreciated!!
