If I remember correctly from the John Clement presentation at Berrien Springs, you should not lubricate the compressor. This goes against my inate drive to lubricate anything that moves. I can think of all the things I have fixed since childhood with a simple drop of oil. It would seem a light (invisible) film of Synpower on the pistons and crank pins would be a good thing. Along with a drop of light machine oil on the motor bearings. This is a possible winter PM project I am thinking of looking at so any insights welcome. Also, is the stock setup on a 77 just a one way check valve or is there pressure relief involved as well for easier compressor starting akin to a shop compressor. Thanks.

I have never lubricated mine.
The check valve works, but adding the unloader helps seat the check valve. Especially if the compressor is in good shape (does not leak air quickly) and the check valve does not like to seat. If you are replacing the pressure switch, get one with a check valve. They are only a couple of bux more.
