I injected some dye and oil a couple weeks ago. The compressor has a very slight amount of dye coming from a spot toward the pulley, but it doesn't appear to be leaking where I suspected. However, the system does have a pretty good leak coming from the connection block near the firewall passenger side. 3 of the 4 connections had strong signs of dye. Are those 4 connections just sealed with o-rings?
