I had my wife's car in for an alignment today. I rarely drive the Flex. I got a call from the dealer about an oil leak. They couldn't find the source, but the pass side of the engine is covered with oil. The put the dye in the engine to find the leak. Is there a common area(s) to look? It is a 09 Flex AWD with 39,500 miles on it. We purchased it used with 35,950 on it from a Ford dealer.

 

The dealer hasn't found the leak yet. They clean up the oil and let it run in the shop and they don't see anything. As soon as they drive down the road it coats the passenger side of the engine and firewall, hood, etc.

Any ideas?

 

They found the leak. The problem was the O-ring on the camshaft sensor on the front bank of the engine.
