Replace the sending unit. Approx. $30 at parts store. I just replace one in my 1992 Wrangler. Requires a special socket ($12.)

you can also use Teflon tape and wrap the threads.

Rarely do the leak around the threads, replace it before it creates bigger problems.

Find out why it is on. The oil light being on may indicate low oil pressure. It may be nothing more than a bad oil pressure sending unit, but it may be more serious. You need to know why it is on. Check your oil level, and if it is full, I would look at the oil pressure sending unit and see if it is connected or leaking. If all looks good seek professional help.

Why does your well pressure tank make a whistle sound when the water is running?

There is an air fitting on the tank, where you can check the pressure on the one side of the diaphragm. Hold you hand over it and see if the air is leaking out here. If air is leaking out here, you need to get a tire valve tool and tighten the pin. If the diaphragm was bad, the tank would completely fill with water and this should not cause that sound. There is a pressure switch, and the plumbing lines, but if there where to whistle, you would see water leaking out.

WHAT WOULD CAUSE no oil pressure in my 944 turbo?

Indication? Bad sending unit. Bad gauge. Bad wiring between the two. Actual No Pressure? Leaking front crankshaft seal. Not enough torque on the crankshaft pulley bolt and the oil pump gear can slip (should be 190 ft/lbs I think). Worn pump gears, but this is rare.
