Like with any oil leak... everything gets dirty... so look for the clean spot, oil will wash away the dirt.
If it is not leaking that much... the best method, (and one you should eventually do), power wash the whole thing ... blow it dry, and check all lines, fittings and associated parts... :smile:KennyV
I try to keep all my equipment clean always.... makes for spotting a new problem easy, and helps with any repair...
