Should there be any air leaking at the compressor? I heard a little air leaking and sprayed the area with soapy water and found it leaking at a brass bolt that's on the side towards the top of the compressor. I tightened it and the leak slowed a lot but didn't completely stop. Next I took the bolt completely out and put some nylon tape on it and it seems to have stopped. I haven't driven the truck since I did this, just wondering if I did anything wrong.
