Well, today I got the nerve to mess with the MR2 again. I relocated the ground wire right under the oil sender,. on the HFH bolt. Since the manual said I needed a engine ground close to the sender that was the closest. Anyways. I started the car and yes I have oil pressure, BUT very little. I would say 4psi max. But before all of this happened I took off the sender and started the car, and oil drizzeled out. Before oil shot out all over the fire wall. The last time I started the car I walked back to the bay and listened to this horrible clanking noise coming from the timing belt side of the car. So I waltz over there and I notice metal particals(very noticable sizes) flying everywhere. I took off the top part of the timing belt cover a couple of weeks ago. I also noticed the belt was pretty loose. So my theory is that the belt is turning the pump but its loose enough to where its eating away at the pump pulley (belt is turning faster than the pulley). Also, when I would drive the car, I would notice a burning rubber smell when I would get over 70mph. I also noticed there is a lot of metal particals built up inside the timing belt cover. Does anyone else have any ideas?? Also When I was looking at the gauge psi went to 4-5psi, then it all the sudden droped back to 0 then it went back to 4-5psi.
