Well, Thanks for all the advice. I replaced the radiator hose and flushed the system (as best I could). Couldnt get to the engine block drain plug with out removing a whole lotta stuff, and I needed to drive to work this morning. So I just filled it with distilled water, redrained, then put a 70/30 mixture antifreeze to water, and now the car runs supercool (driving in the mountains it dosent go above 1/4 way up the guage). Strangest thing is, when I let the engine warm up, (slow driving for 20min) the noise in the tranny goes away. While I had the car on jackstands I tightened everything up that I could, and cleaned the underside of the car (was pretty oily). I was thinking exhaust because it goes away when its warm, but it seems like a pilot bearing (when I take my foot off the clutch and the engine is cold it makes the noise, clutch in and the noise goes away) but when its warm no noise and the car runs great. I was hitting 6k rpms with it last night and it didnt miss a beat (after warming it up for an hour of course). I checked the coolant again today and no oil yet, so I think its alright.

By the way, what are the cylinders with little white notched knobs on the bottom of them that are in the driver and passenger side bottom of the front bumper. Are they for adjusting the suspension? Couldnt find them in the manual. Thanks for your input everybody.

I think you're looking at the knobs to manually raise/lower the headlight buckets although, I don't recall what color the knobs are as mine still have the rubber covers on them. I could be wrong but I can't think of any other knobs under the bumper.
