There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.
The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.
A severe lack of power may develop because the hose from the turbocharger to the intake manifold can come loose, resulting in loss of boost pressure to the engine.
The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.
The rear sliding glass window may stop working, or binds in motion. The power slider cable binds causing slow, or no operation. The glass assembly will need to be replaced, the cable is included in the assembly.
Our technicians tell us the spark plugs in these engines can be very difficult to remove. Ford has issued a service bulletin (08-7-6) to address this issue, which includes a recommended procedure on how to remove the plugs. Failure to follow the recommended procedure can result in the one or more spark plugs breaking off in the cylinder head.
The recommend procedure is as follows. Using this procedure will greatly reduce the chance of breaking a spark plug.
1. Break the spark plugs loose when the engine is warm.
2. Turn each plug 1/8 to 1/4 turn and soak the treads with 1/2 to 3/4 teaspoon of Motorcraft Carburetor Tune-Up Cleaner or a quality penetrating oil. Do not try to remove the plugs at this time.
3. Let the threads soak for at least 15 minutes.
4. After the soak period, tighten and loosen each spark plug, working it back and forth until the turning effort is reduced. Then, you can remove the spark plug.
There are special tools available to remove the broken spark plugs and repair shops will often charge additional labor time, over and above the quoted spark plug replacement cost, for the removal of each broken spark plug.
It is common to see the variable vanes inside the turbo seize or bind from carbon buildup. This causes an overboost or underboost condition when driving.
