Many class action lawsuits have resulted from the numerous problems that arose frequently. There are many claims that the early 6 liters were the most problematic, though it is debatable if there truly is any significant correlation between model year and reliability. A common perspective, in which we support, is that the 6. L and its problems were hit and miss. The engine is undoubtedly more temperamental than diesel owners expected. The good news is that most trucks on the road today have received adequate repair andor have received updated parts, and therefore are less prone to future failures. The problems typically arose quickly, early on in the engines life cycle, and therefore the trucks on the road today are much more reliable than they were coming off the assembly line. We hope the following information helps current 6. L Power Stroke owners and prospective buyers better understand, diagnose, and prevent reliability issues. Note problems are not listed in any particular order of frequency or significance. TTY Head Bolts. The 6. L Power Stroke cylinder heads and secured to the engine block via TTY torque to yield head bolts. TTY bolts are a one time use fastener once they are stretched during the assembly process, they must be replaced if they are removed. From an engineering standpoint, the head bolts are sufficient for there application. In a completely stock engine, their reliability is not of major concern. In applications where performance has been increased via aftermarket components, cylinder pressures may rise beyond the limits of the head bolts, ultimately causing head gasket failures. Additionally, the EGR system has been known to contribute to engines to run hotter than expected, which may lower the yield point of the head bolts and in some situations even warp the cylinder heads.

If any performance modifications are to be performed, head studs and new head gaskets are highly recommended. EGR Valves EGR Coolers. L Power Stroke EGR exhaust gas recirculation valves and EGR coolers commonly fail andor contribute to reliability concerns. The EGR valve is an emissions device that controls the amount of exhaust gases that are reintroduced into the engine, essentially diluting the intake charge to reduce NOx emissions. The EGR cooler is responsible for cooling exhaust gases before they are reintroduced. It is essentially a heat exchanger, in which coolant and exhaust gases flow through. The EGR cooler is responsible for higher than ideal operating temperatures, especially under load. Both are prone to failure, the common culprit being soot buildup. When soot builds up in the EGR cooler, it can become clogged and the excessive heat can boil coolant in the exchanger. The EGR coolers have also been known to fail and leak coolant into the exhaust system white smoke is typically noticed coming from the exhaust, which is steam. Power Strokes have a round EGR cooler, which is less prone to failure than the less efficient square cooler found on 2. The EGR valves may build with soot and cease to function. If the valve sticks in the open position, a loss of power may be experienced. Excessive carbon buildup on the EGR valve is extremely common on every model year 6 liter. Poor fuel quality and excessive idling will contribute to EGR clogging. Clean the EGR valve at every other oil change to keep it functioning properly. If your engines oil cooler fails, consider upgrading to an aftermarket unit, or replace your 2. MY cooler with a 2. What Are The Difference Between Sequential And Indexed File System. MY unit. Oil Cooler Failure Replacing the oil cooler on a 6. L Power Stroke is an expensive operation. Residual sand not removed from the cooler after being casted contributes to clogging of the coolant side of the cooler. Poor oil quality can also clog the oil side of the cooler, and occasionally the oil cooler gaskets have been known to fail. An oil cooler failure is suspect if oil is present in the coolant or visa versa. Buy NavistarInternational Diesel Injector Driver Modules IDM Online with Shop Injectors. Ford Super Duty Powerstroke Part Numbers. This is a list of common parts used in a Ford F250, F350 Super Duty trucks and other trucks with a Powerstoke motor. For the fastest shipping and lowest prices call NEAT COMPUTERS 9542700005 httpswww. To reduce the chance of failure, change your engine oil and coolant at Fords recommended intervals. You may also consider investing in an aftermarket coolant filter to remove particulates from the engine cooling system. L Power Stroke FICM Failure The FICM fuel injection control module resides on the driver side valve cover of the 6. L Power Stroke. The FICM is an electronic component, and is bound to burn up at some point. However, engine heat and vibration is known to contribute to premature FICM failures.

PowerStroke and Torqshift Transmission. Click here for 6. Bulletins. The HiVHiHz IDM is a rebuilt unit, which has been modified to increase both the voltage the frequency of the signals that fire the fuel injectors. FICM failures are responsible for a number of rough running, no start, hard start, and stalling conditions. They can be tested and if it needs to be replaced, consider having it professionally rebuilt from a company whom offers a warranty on their repairs. There are a number of options out there and many of the rebuilds are of higher quality than the originals. ICP IPR Sensor Failures The ICP injection control pressure sensor relays oil pressure in the high pressure oil rail. The IPR injection pressure regulator is located on the back of the high pressure oil pump and controls pressure in the high pressure oil system. Both sensors have been known to fail prematurely. To the best of our knowledge, the replacement ICP and IPR from Ford are upgraded components and not as problematic. Sticking HEUI Injectors HEUI hydraulically actuated electronically controlled unit injector injectors rely on high pressure oil to pressurize fuel in the injector body, as opposed to utilizing a high pressure injection pump. In a simplistic model, an oil pump pressurizes engine oil and sends it to the injector, and a pistonplunger in the injector uses the oil pressure to pressurize fuel before it is injected into the engines cylinder. HEUI injection systems were advanced when they were introduced by Caterpillar in the 9. The injectors are sensitive to poor fuel and oil quality. The best thing you can do to prevent failure is maintain proper fuel quality by means of an additive if necessary and keep your engine oil changed regularly. The 6. 0. L injectors in particular are prone to stiction there are several additives on the market that prevent and in some cases even reverse stiction problems in these injectors. Archoil is amongst the leading manufacturers of stiction eliminating oil additives, and we use their Archoil AR9. High Pressure Oil Pump Failure The Power Stroke HPOP high pressure oil pump is a swash plate style pump that pressurizes engine oil to more than 3,0. The high pressure oil is used compress fuel in the injectors. The HPOP on the 6. L Power Stroke has been known malfunction from leaking seals to complete failures. Its worth noting that the pump is considered a wear item and is expected to need to be replaced at some point regardless. However, the 6. 0. L pumps are notorious for needing replacement sooner than expected. Electronic diagnostic equipment can be used to verify whether or not the pump is operating within spec. At wide open throttle with a load i. At idle, oil pressure is typically in the 6. A minimum of 5. 00 psi is required to fire the injectors if pressure drops below that, the engine will stall. Turbocharger Lag, Sticking VGT Vanes, Turbocharger Failure The 6. L Power Stroke is equipped with a VGT variable geometry turbocharger that uses a series of mechanisms called vanes to increasedecrease the effective volume of the turbine housing.
