Actually mine has been seeping oil from there too. I thought it was the Crush washer.
Before that I thought it was the oil pump leaking but after i redid it once, i checked the line under the fuel injector cover and there was oil around it. Unfortunately, it looked to pool up a bit on top of the head and then drip down by the oil pump onto the exhaust overpipe. The burning oil caused the ceramic coating to chip/flake off of my AVO overpipe and a chunk of it is bare stainless steel now.
Anyways, I re-used the brass crush washer but made sure to teflon tape the bottom part of the threads on the fitting into the block. I'll let you know if it solves the issue, if not, mine may be the line as well. I also torqued that bastard down pretty tight. I would of used a new crush washer, but the fitting was way smaller than I expected and didn't have a new one.
