Well I have been trying to track down a high side line for my SHO and had been unsuccessful after I had my current one repaired and it started leaking. Anywho, about a week ago we went to the flea market and on the way home the a/c started cooling kinda crappy, so I just shut it off. When I got in the driveway I opened the hood and put my hand on the low side and high side lines to get an idea of whats going on. I put my hand on the low side and it was kind of luke warm, then I put my hand on the high side line at the muffler and I about burned my hand, it was hot, WAY too hot. So I went inside figured it was restricted, maybe froze up. So I went back outside about 20 minutes later and the line was leaking. Fast forward to today, I was able to track down a brand new line and started to install it. First thing I noticed was the oil that was on the a/c pulley -- shaft seal is now blown. I removed my line that I was going to replace and looked into it. About 2 inches into the line, still in the metal segment was a small round peice of metal. About the diameter of a pen and perfectly flat. What it reminded me of is a pneumatic air punch for making plug welds, the metal that the tool pops out like a hole puncher. The peice of metal was wedged in the line and basically blocked the line. I popped it out and it had no signs of going through the compressor or anything like that -- although I am completely stumped on how this thing got in there. So I installed the new line and blew the lines out w/ compressed air and brake cleaner to see if I got any metal. I disconnected all the lines and did them individually, the condenser, evap, orifice line, and the accumulator lines, no metal at all, just dye and oil. So i vacuumed the system down and started to recharge it and refrigerant starts blowin like crazy outta the manifold o-rings.
Anyway, moral of the story is. Whatever that was in the line caused such a restriction that the a/c compressor was basically deadheaded and it blew through on that new line I had made, it blew the shaftseal and the manifold o-rings. I have a brand new compressor from the same place that line came from, all Motorcraft parts on order, it will be here in 2 days. I just can't fathom where that peice of metal came from. Hoping maybe someone here has an idea.
Just FYI the old compressor still works fine, just needs some new o-rings now. It turns smooth as silk.
