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.
The oil pressure sending unit could be bad. Or the oil pressure gauge could be bad, but normally gauges don't fail............I would have someone check out the oil pressure sending unit.
Leaking heater core
check your pinion seal
Depending on mileage--could just be a sign of engine wear Remove oil sending unit and replace with mechanical gauge to determine actual pressure
Low oil pressure or a defective oil pressure sending unit.Low oil pressure or a defective oil pressure sending unit.
If you checked the pressure with the sending unit in the car, it is possible the sending unit itself may be bad!
Perhaps leaking valve cover gasket? Perhaps leaking oil sending unit?
1. The fuel pump may be going bad. 2. You dented your fuel line and the pump is making more pressure and sending fuel out the cap. 3. clogged fuel line. 4. clogged injector's
It developed an leak and then for whatever reason sealed itself. Replace the oil pressure sending unit.
Yes, if the oil pressure sending unit is bad the oil light may come on.
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.
You would have a leak in the coolant system somewhere and you need to have the system pressure checked.............
