One problem related to crankcase (pcv) has been reported for the 2012 Ford F-350. The most recently reported issues are listed below.
My truck has 32,000 miles on it. 6. 7 diesel. Upon starting the truck ( stationary in my driveway ) #3 fuel injector popped out of the engine, causing a misfire and spraying diesel fuel all over the engine. It was found that the #3 injector hold down clamp had broken caused by a crack in it. . Ford is well aware of this defect. . This could have resulted in a fire and possible loss of life if it had happened on the highway. Ford agreed to replace half of the defective injector clamps. (4) this leaves the other 4 prone to fail at any time. I was charged $897. 67. For the" half repair". Ford should be forced to recall these vehicles as it is a well known failure and documented on numerous internet websites. There is a TSB from Ford to their dealers on it. It also filled the crankcase with diesel fuel which did not do it any good. This truck has only 32 k miles and has been meticulously maintained since new. The Ford dealer repair order states:"found vehicle leaking fuel. Found injectors # 1 & # 3 blew out breaking hold down clamps. Also found other clamps cracked and return line broke as well and leaking fuel. Ordered parts on back order paco # 5934349 contact Ford case # cas-15233762-q2p6to. Ford agreed to assist $ 1500. . Ford should pay for the whole repair because it is a defective part that caused this dangerous failure and they are aware of it. Please force them to initiate a recall on these defective fuel injector clamps on their 6. 7 diesel engines before there is a catastrophic failure resulting in vehicle fires. The engine will most likely shut down if the vehicle is driven with the injector out of the engine. If someone was towing a trailer this could be life threatening. Luckily mine failed in the driveway with the engine at idle. .
