I noticed an exhaust leak from the passengers side exhaust manifold. Turns out the weld that hold the exhaust manifold to the rest of the exhaust has failed, it is now being held up by exhaust hangers and metal strapping, until it will be repaired.
Engine check light came on so I took the car to a local dealer. He informed me that the eec test code was p0411 which deals with emissions. When the dealer removed a hose to inspect the component, water came out of the hose. The dealer informed me that the entire air pump was full of water and had "burned" out as a result. I will have to have the pump and relay replaced at a cost of $275 for parts and $120 for labor. He further informed me that this was extremely rare and he did not know how the water could have gotten in to the pump. I called Ford customer care and informed them of the problem and they informed me that they had no other complaints of this nature, but would file the information away for future reference. According to the dealer, this "problem" does not affect driveability of the car, and since virginia doesn't require emissions control testing, there is no requirement to have it replaced, however, the "check engine soon" light will remain on until the air pump and relay are replaced.
Vehicle was leaking oil from underneath the hood. Also, consumer was traveling about 65mph and looked though rearview mirrior and noticed black smoke coming from the exhaust pipe.
