2011 Ford F-150 SuperCrew XLT 4dr SuperCrew Styleside 5.5 ft. SB (3.7L 6cyl 6A)
I bought my truck used with 55K miles on it. Ever since I bought the truck it has had the common issue of engine shuttering and going into limp mode. I have spent over $6000 attempting to fix the issue. I bought new Full Race Intercooler, throttle body, cold air intake, turbo power pipes, new coils, new plugs 4 times and new exhaust. It still shuttered every time I sped up causing the condensation build up from the intercooler to enter the engine all at once and foul the engine. I then went as far as drilling holes into the lower intercooler, engine side, of the pipe at its lowest point to let all the water continue to drip out. It was ALWAYS Dripping all the time. Yesterday while hauling a car trailer with the truck from Colorado to Texas, all the sudden the engine shuttered one last time, as I again coasted to the side of the road only to find engine oil coming from under the engine. There were NO warnings!!! NO rise in engine temp during entire trip, and engine lights. When I checked the oil it was still within the "add oil" hash marks even after losing some on the ground. After towing it home I have since found out it broke a connecting rod and the engine is finished at only 101753 miles on it and I will now have to buy a new engine!! I feel the issue that Ford has had all along with the condensation build up in the intercooler is the ABSOLUTE cause of this engine failure!!! Constant and at times VERY severe shuttering will cause severe damage to the connecting rods, crank and pistons while misfiring like this, causing the engine to sooner of later fail like mine just did.
