OK, I've figured out that it's my expansion valve thats leaking slightly, meaning that the A/C charge/retrofit to R134A (done late Spring '03) is still within specs and works fine but the seeping oil has destroyed the insulating wrap (now a black goo) around the lines. The picture in Fastlane doesn't show much, and I've read this thread, how much of the dash will have to be removed to get the valve out. As you probably know there isn't much room to see or reach it. OR could it be that the one line that seems to be leaking just needs to be tightened up, I presently live on a dirt road and the car gets shaken every day going in and out from my house. PSST, I've done a lot of mechanical work over the years using nothing but the eyes on the end of my fingers so if anyone has a picture (from a manual would be great) of how the thing is mounted with the screws shown as well I can figure this out. Thanks.
