I just purcahsed a '73 1800es. I'm quite happy with it despite a few cosmetic defects (slight rust both repaired and not). It handles well but it seems the wiring may be a mess (non functioning clock, radio, speedo). But I'll leave that for another post. What I am most worried about is that when at idle, the oil pressure gauges reads very low, close to 0; and the oil tempature gauge reads very high, into the red. I read that the oil temp gauge shouldn't get a reading until after about 20 minutes of driving, could this mean a bad gauge or bad oil temp sensor? After steady drivng the oil pressure gauge will almost reach 70, the red oil light still flickering, and the oil temp gauge will sometimes move all the way left indicating the lowest tempature possible. I am baffled, could it also be a bad oil pump or a clogged pick up screen? It makes me nervous to drive the car in this condition so any help would be greatly apperciated.

Thank You.

Adam.
