[ccbyrne]

first time posting pics...hope i did it right
its a 2001 explorer sport, 4.0L

alright so i checked under my car today, just had a oil change done, and i noticed this leak. never noticed it before, that doesnt mean it hasnt been there though. not sure what it is, any ideas?

^in that picture, you can see the white oil filter if that gives you guys a bearing of where it is

thanks in advance

Hard to say, it could be a crankshaft main seal, transmission pan gasket, leaky front pump seal on the transmission, or oil dripping down from a leaky valve cover gasket. Clean it up and keep an eye on it so you can determine the source.
