Ford 7.3 Power Stroke -owners say that these are the most common problems – Jalopnik

Few oil burners carry just as much weight as the 7.3. It was the first Ford engine that bears the now legendary name of the stream, and the mechanical ingenuity meant that it not only created a buzz, but also defined an era. The 7.3 Power Stroke was created as a result of years of collaboration between Ford and the International Truck and Engine Corporation, ITEC (later Navistar) that started with the introduction of the ITEC supplied by ITEC, of ​​course 6.9-liter indirect injection (IDI) diesel engine in 1983.

In 1988, the relocation of the engine was increased to 7.3 liters thanks to a larger bore, which resulted in more power in the process. Further improvements were made in 1993, with the 7.3 Idi received a turbo compressor. Only in 1994 was the original Power Stroke Turobodiesel engine born. Faced with heavy competition from the Cummins Turbo Diesel engine that was introduced in 1989 for the Dodge Ram Trucks, Ford International Navistar developed a motor that was resistant to Chrysler’s attack, which is why the 7.3 Power Breeding brought more than its predecessor.

Compared to the departing 7.3 that a mechanical fuel system had with indirect injection, the 7.3-liter current spot used an electronically controlled fuel system with direct injection, whereby the Huei fuel injectors spray the diesel directly into the combustion rooms at a maximum of 21,000 PSI. Popular with Jalopnik readers, the original engine stroke engine also had forged steel connecting rods (later models were equipped with powdery metal connecting bars) as well as cast iron block and cylinder heads, with six cups of 12 millimeters per cylinder. The result? A huge successful engine that built up a reputation for reliability during his production run, which lasted at the beginning of 2003. But that does not mean that it was perfect, because owners encountered problems, including with the CAM position -sensor and injector -drivers module.

Many messages from owners on different forums and Reddit-Threads suggest that exhaust pipe errors are one of the biggest problems with which drivers of Ford vehicles are powered that are powered by the 7.3 Power Stroke. It is known that the legs installed by the factory leak gases because the ends of the pipe are chewed from the seal, according to a post per member So On the Power Stroke Forum. By a Engine -boning Post, the design of the engine has a crushed donut gasket that seals the up-pipes to the y-collector of the turbocompromator to prevent the exhaust gas from the engine from the engine leaking.

However, these donut packages are wearing the tendency to wear out prematurely because of heat and pressure, which leads to the problem of the exhaust leak they want to prevent. Of course this lost air pressure limits the amount of exhaust gas that comes in to turn the turbine wheel. As the air fuel ratios are disturbed, owners will normally experience reduced engine power and reduced fuel efficiency, partly because of the engine that works hard to compensate.

The engine can also make the engine susceptible to excessive exhaust gas temperatures, which can eventually damage the turbocompressor if it is left for too long, which requires a replacement. If your situation requires such a change, some 7.3 owners recommend power to replace the factory units with roaring up-pipes that make expansion and contraction possible without failure as a solution to this problem.

As you may already know, the cam pass position sensor is a device that measures the exact speed and position of the crankshaft together with the crankshaft sensor. It then passes on this information to the Motor Control Module (ECM), so that it can determine when it has to spray fuel and how much fuel must be injected. Unfortunately, owners say that the CAM position sensor on the Ford 7.3 Power Stroke Engine can fail or can wear out prematurely. This influences the transfer of information to the ECM and is usually one of the common reasons why your engine will not start. Fortunately, replacing the 7.3 Power Stroke Cam position sensor is a relatively simple and affordable undertaking that you should not cost too much, because it is accessible without much effort and is not expensive to buy.

Another device that can cause starting problems (and the vehicle that runs roughly and intermittently stuck) with the 7.3 Power Stroke engine When is defective, is the Injector Driver Module (IDM), which helps to control fuel injectors so that they shoot at the right times. This component can be damaged by water that enters the IDM through ventilation openings, which endangers the device. When this happens, the 7.3 Power Stroke can refuse to start unexpectedly, misfortune, hold or lose power. Other common problems that owners reportedly have experienced with the 7.3 Power Stroke Engine, include problems with the Under Valve Cover Harness Connectors (UVCH), failed injector control sensor and clogged fuel filter, which can reduce motor performance, can reduce the fuel consumption and even some overheat.
