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!
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.
Perhaps leaking valve cover gasket? Perhaps leaking oil 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.............
bad sending unit, or bad regulator.
CFI ? The fuel pressure regulator could be leaking.
What kind of car and engine. These are required to answer the question 1994 Pontiac Boniville 3800 engine code L The oil pressure sending unit is located just above the oil filter, that is one possibility.
water pump leaking at seal hard lower radiator hose or loose clamp hardened or punctured bypass hose shrunken timing cover gasket thermostat gasket shrunken
maybe your radiator is broken and you need to get a new one or just get a reparation if the radiator starts leaking when is in use it may be leaking because of the pressure of the water.
Why in the world would you want to do this? If the sending unit is defective then replace it. If the light is on you either have low oil pressure of the sending unit is bad. Low oil pressure will ruin your engine.
the ac drain is stopped up locate under hood on passenger side on fire wall
Without seeing or pressure testing the system my most educated guess would be that the intake manifold is leaking.
Have you change the oil pressure sending unit, that's what I had to do. David
the lead that goes to radiator came out, when l put back in would not hold and now leaking, water pressure was low and water is funny colour (kinda red)
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.
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.
No, it will not.
