Were started getting oil smell also, so I washed the pan/engine down real good & let my wife drive it a few days (I left the plastic cover off the passenger side) & Im not sure but its maybe coming from the front engine seal. The seal part is less than 20 bucks so Im up here looking to see if anyone has changed this & how much trouble it was to replace. It doesnt look to hard to replace.
