2010 F150 Oil Leak
 

I've been losing a little oil (enough to raise concern). When I have truck idling I can see a whisp of smoke from under the hood. The only wet spot I have found is what appears to be a hose to the radiator area. At first I thought this just had residual oil from when I last changed the filter thinking that I spilled some oil onto the hose/line. Is this an oil line to a cooler? Hose is connected to steel lines, and rubber part is wet. Is this connected by the same type of quick connections such as those used on gas filter? What hose is this? Between front of engine and radiator down low.

If you are sure it is engine oil then look for engine leaks. It could be oil from power steering or the trans cooler. Generally,,,,,,,,, engine oil appears black, power strg clear or not black, trans oil red or dark red. You may need to clean the area with a can of spray brake cleaner , then watch for the source of the leak..

Agreed...
