I have 2011 pilot ex. I just bought from my dad. It was due for oil change. Put it on a lift and noticed oil all over the bottom of the oil pan and on the oil drain plug And other parts. So i had my mechanic change the oil and put a new washer on and he sprayed cleaned bottom with break cleaner. A week or 2 later and driving it places, I check And the oil was there again. Check oil level and it seemed to be the same level. Mechanic looked again on the lift. Looked like an bolt above the the drain plug n pan had oil on so he tried tightening it but as already tight. Cleaned oil off again. He even started the engine and left it run. Didn’t see no oil. Ran it and checked every few days no more oil leak. Even had him put a new tire on. No leak but yesterday I looked and you could see oil there again but this time it looks like a thin film. The mechanic still thinks it just left over some may have spilled on the engine. Help.
