The other day I pulled my AC compressor loose so I could get to the no. 1 plug (yes, I'm a woosie and run AC). There was a small spot of oil on top of the bracket - about the size of a quarter. It seems to operate fine and the pressure / level is good, but it has always seemed to have more parasitic drag than I'd expect. Is this something I should be concerned about?
Thanks for any thoughts and advice.
