Clean air filter element and check for other restrictions in the intake system. At any rate, right smack dab in the middle of the A/C fix research process, and totally unrelated, I ended up buying a real nice, relatively low mileage 1976 Chrysler New Yorker. Do not run the compressor for more than 25/30 min in order to avoid overheating (not only for the compressor, also to avoid too much oil and water vapors), remember, water and oil can find the way to your air reservoir, build up and make a mess!. Look for oil residue around the hose ferrules, fitting connections at the compressor, condenser, and evaporator or expansion device. Insufficient oil can cause premature compressor failure. If a rotary screw compressor runs, for example, below 160 all the time, it is running too cold. During the manufacturing of the Atlas Copco compressor oil filter, pleat continuity is maintained and pleats are uniformly spaced to assure full usage of the entire filter surface. While the use of the crankcase oil equalization line has been an acceptable practice, many multiple 06D & 06E compressor systems now use oil float systems (floats, oil separator and oil reservoir). This excess pressure inside the crank case forces engine oil by the pistons as well as out through the breather and into the intake - then it enters the turbo as a very fine mist. I have read that too much oil is not good for the compressor and it can indeed prevent it from cooling as well. This makes the compressor work harder which increases energy and maintenance costs and, subsequently reduces the life-cycle of the compressor. Charging pump and easy filling.
