3.5L V6Engine Block Casting Failure
mikea1949 posted a topic in 3.5LMy wife loves her 2007 Edge SEL AWD and it has been an excellent vehicle for 112,000 miles. Recently, we took it in for service- clean heater air intake filter, service engine. When we got car back I noticed a few drops of oil on floor. Didn't think much of it as figured it was oil spill on engine from service. A few days later the leakage increased and the bottom of the car was covered. Crankcase still had oil on midpoint of dipstick. Took car into dealer for evaluation expecting a loose hose, oil filter, drain plug. Instead they reported and showed me oil coming from a vent in the block casting below alternator and just behind front engine cover. Dealer checked with Ford and received an email reply called an SSM(?) - a report that is not generally published from Fordtechservice.dealerconnection.com dated 19 March 2008. The report noted that engines built with date code between 1 April 2007 and 31 July 2007 may experience leakage of oil into the cooling system as a result of casting porosity near the main oil galley in the engine block. Corrective action is to replace engine at $7,200. Can anyone confirm this issue or that Ford has some available mitigation for this severe failure? Is there another problem that may be less severe related to oil leakage from this casting vent? Thanks for reading, MikeA
