yeah. i did. i just cut both lines, ran a hose to the one that blows out to the tank and left the other open to suck in air. but if it gets low on oil it gets really hot and blows lines.
i second all that also just swapped out my motor and debating putting my ac back on or use compressor for air and next summer get electic and put ac back on then.
water trap yes, oiler depends on what kinda of compressor you have.Sanden you need an oiler, wich are stock a/c compressors for the truck and some if not all yorks you put oil in the compressor
