Expert A/C Help Wanted! Part 2

I have really appreciated all of the help I have gotten on this problem sofar.Here is where I am today...The entire A/C system has been removed from the vehicle while I amrebuilding the engine. I have reassembled it in the bed of the truck to keepit sealed up. I just bought this truck with a blown engine so I do not have all of thehistory but I can still talk to the PO. He was up front about the fact thatthe system was leaking and that he had the shop put in a dye bomb and theycould not find the leak. The engine blew a head gasket about a month afterthat so he never had a chance to check it any further.I want to find any leaking A/C system parts while I have the engine out. Itwould be way easier to replace them now then later.I was an idiot (in my previous posting) and was not using the black light tolook for the leaks but now I have one. Thanks for the education! I havealways been told that ignorance is curable but stupidity is terminal.Now that I have looked over the system the right way, I still cannot findany leaks so I am frustrated again.The PO said the system would leak down in about a weeks time, so I wouldthink the leak would be pretty obvious.Since I could not find any trace of the dye, I opened a fitting and lookedinside there. Sure enough the dye was glowing a greenish yellow color so Iknow the dye is visible under the black light I have.I looked under the hood above where the compressor mounts and behind thepulley and saw no traces of dye (under the black light) so I am thinking thecompressor seal is "probably" not the source of the leak. If it was I wouldexpect that the pulley would have made a nice stripe across the inside ofthe hood by now. I could be wrong though, God know I have been wrong enoughtimes before.I think the only part of the system I cannot physically see is the part ofthe hose that is wrapped in the heat protective shield where it passes overthe exhaust manifold. Other than that I am stumped. Should I cut this offand look under it, or...

Thanks for clarifying. You had me scratching my head and there would have been "raw pots" before too long I'm sure! :-)
