My Suburban has recently been leaving a large spot under the rear part of the engine where it joins the transmission. Checked all fluid levels. All good. Not sure...believe it is fuel. It will evaporate after a few days leaving just a small oily spot. Can also smell fuel under the hood. I cannot however find any leaks. Thinking maybe under the filter housing? Anyone have any idea? Experience the same thing.
