Hello: I just purchased a 92 olds achieva 3.3l v6 131k; I have a few problems that I need help with;... for now its my oil pressure; the car runs fine but the oil gage upon start up goes to 70 and if left to idle after a few minutes it will gradually got down to 40 and the "check oil" lite comes on. Also when driving it will stay at 70 but when you come to a stop it goes down to 40. Am I doing any damage by driving this way? What should the optimum driving level be at? I did get a oil/filter change and that didnt solve the problem. Any help would greatly be appreciated thank you

I have a 2.2 Chevy Cavalier, 1996. The problem is that one of the flywheel bolts is rubbing when I start and drive the car. I can hear it click while the flywheel is turning but I can't see what it could be touching. The bolts themselves are tight. Also, when I shift from park to drive the sound stops while the gear engages, then goes back to clicking. Short of the flywheel being warped, I'm at my wits end here. Any help anybody could give me would be greatly appreciated.
