Now we're getting somewhere. Yep, sometimes a bit of a sacrifice, (getting into the mud, been there done that oh, about a few dozen times) is what it takes.
Nobody likes doing these types of repairs, corrections, maintenance etc. but, in the justice of "seeing for yourself" and, knowing the job can and will be done right, without being gouged.
Dirty shirts, pants, cut hands, a few choice words, and the job is done. You now know more than you did previously. And, if by some strange chance, you see oil on the ground again, in the future sometime, in the same possible area, you might have ammo to dive right into the potential spot. Hope the fix is simple.
