Why is the check valve on my air compressor leaking?
The check valve prevents tank air from back flowing to the pump and unloader. If air leaks out the unloader when the pump stops, replace the check valve because the check valve leaks air back towards the unloader.
Is it normal for a compressor to start leaking air?
Yes, but only until the cut in pressure in the tank was reached, and then the compressor would start again. If the air is leaking out of the tank after the compressor stops, it can only be 1) leaking tank check valve 2) leaking tank drain valve 3)leaking discharge coupler 4) pin hole in tank.
Why do I have trouble shooting my Porsche air conditioner?
For R12 systems, if you see a strong stream of small bubbles you are low on refrigerant. With R134a systems or conversions we are not to concerned with refrigerant flow observed at the sight glass because the flow can be cloudy and little if any (with R134a you are more concerned with pressures and temperatures).
What causes a Porsche air conditioner clutch to slip?
Clutch turns but slips. If the front hub on the compressor seems to “slip” (we are not discussing the belt here) you could have two potential problems: The air-gap between the faces of the front hub and pulley is too large. This does not happen often on it’s own, more probably if the compressor was overhauled.
What should I do if my air compressor is leaking?
If you plug in the compressor, the pressure switch response to the air leak and dropping compressor pressure will be to start the compressor again. To try and find the leak, do the following.

Why do I have problems with my air compressor?
An air compressor problem could stem from one of many issues, such as an air leak, an oil leak or a broken part. In some cases, you might have insufficient pressurization or air flow.
