check and make sure your pulleys all turn, you could have a bad bearing thats fuckin you up, just for the hell of it, check your power steering fluid too, if it ran dry, that could cause it to burn up....as far as the other problem, the way i have it figured out, is the oil pump on a DSM either works, or it doesnt, but the way they are designed would suggest if it was going to fail or start failing, it would just completely go out and leave you with 0 oil pressure altogether, im not claiming this to be the word of god, but like i said its what the design of the pump suggests, may not be a bad idea to pull off your valve cover and make sure oil is still getting to the head....also if i remember, your car is a 90 with those awesome 90 electronics, which may be contributing..im sure its just something with the electronics, but definitely take all safety measures to make sure everything is good...but ya, dont let your car overheat or im gonna beat your ass
