Air Compressor Pump Leaking Oil

Let the compressor pump up and turn off then use a mixture of dishwashing detergent and water to test for air leaks on and around the compressor.

Air compressor pump leaking oil. Excessive oil in compressor. Excessive oil in the chamber if there is more oil in the chamber than necessary the excess oil will obviously leak from the chamber. Check viscosity and change oil if necessary 5. The sump vents out the oil fill plug and voila you have air coming out the oil fill cap.

The air manifold leads from the tank to the coupler into which you plug the air line connector and usually contains the pressure regulator. Clean air filter element and check for other restrictions in the intake system. If the valve plate or a reed valve inside the compressor is damaged it will cause the compressor to pump oil. Piston rings installed up side down.

Also excess oil in the air compressor oil filter will cause the oil to leak as well. Help us on patreon. This video is part of the heating and cooling series. In the latest instalment of gt air projects we show you how to change and service a check valve non return valve or one way valve on an air compressor.

Drain down to bottom of threads. Compressor air intake restricted. In one scenario a fitting is loose on the air manifold of the air compressor. If air is entering the oil sump while the compressor is pumping compressed air that tells me that the piston seals are badly worn or nearly worn out and air is bypassing them into the sump.

Oil in discharge air. This video goes over a few main reasons why your air compressor pressure switch or unloader is leaking while the compressor is running or when it shuts off.
