7.3 L Power Stroke Engine Overview

The Ford 7.3 L Power Stroke engine is a diesel engine that was produced by the Ford Motor Company from 1994 to 2003. It was designed as a replacement for the 7.5 L gasoline-powered V8 engine in the Ford F-250 and F-350 trucks. The 7.3 L Power Stroke is a V8 and is the largest diesel engine offered in a production pickup truck by any automotive manufacturer. All versions of the 7.3 use electronically controlled “smart” common rail fuel injection, turbocharging, intercooling and aftercooling with an air to air system.

It is the first diesel engine powered by common rail technology. Common-rail technology was originally developed in Europe, where it has been used for decades. From its European origins, common rail engines have recently become more popular in North America due to their increased power output and reduction in emissions over older indirect injection designs. The 7.3 L Power Stroke uses a Bosch high pressure pump which operates around 20,000 psi (138 MPa) – the highest ever put into an automotive application before or since its production. This common rail system also applied immense amounts of piezoelectric pressure to inject the fuel at a much higher velocity and with increased accuracy compared to any previous diesel injection system. This rail pressure is supplied by a massive high-capacity water cooled condensor attached to the engine’s exhaust manifold, which also serves as the mounting location for the two high-output turbochargers that provide up to 45 psi (310 kPa) or 102 SCFM of boost supply air. The 7.3 L Power Stroke’s electronic engine management system is heavily influenced by modern aircraft engines such as those by Rolls Royce and General Electric, using an advanced 32 bit microprocessor manufactured in the U.S.

Ford 7.3 L Power Stroke Engine life expancy

Ford 7.3 L Powerstroke Review

Robust, iron parts, conservative power and low engine speed are the key ingredients for any diesel engine lasting forever—and if a 7.3L has gone unmodified yet been well maintained its entire life, 400,000 to 500,000 miles is virtually guaranteed. However, if you modify your engine with things like bigger turbos, more aggressive tunes or aftermarket injectors, that life expectancy goes down. Many Power Stroke owners have reported seeing the typical failure around the 250,000-mile mark when those modifications are made. It’s always a gamble modifying any diesel engine, and the 7.3L is no exception.

Common Issues with 7.3 L Power Stroke Engine

As reliable as the 7.3L may be, it’s not immune to problems. The most common issues include failed fuel injectors (usually caused by running biodiesel), leaky head gaskets (often due to overheating) and blown turbochargers (usually a result of too much boost). All of these problems can often be avoided by keeping your truck well maintained and following the scheduled factory maintenance.

  • Power Stroke Engines Seized

It is no secret that the major problem on the 7.3 L Power Stroke is head gasket failure which results in coolant entering into the cylinders causing them to seize up while driving, often with catastrophic results.

In order to prevent this, the head bolts must be torqued down properly in a specific pattern. If they are not done so, it can cause the gasket to fail.

  • Turbocharger Failures

Another issue that is common on the 7.3 L Power Stroke is turbocharger failure. This may occur because of dirty or contaminated oil which can damage the turbocharger over time. It may also occur due to the lack of lubrication in the turbocharger or ignition problems that can cause pre-ignition resulting in turbo failure.

  • Transmission Issues

The 7.3 liter Power Stroke has had numerous transmission issues; some are unique to certain years while others seem random and do not follow any discernible pattern. One issue common among many Power Stroke owners is a grinding noise that occurs when the truck is put into gear. This problem can be fixed, but it is often expensive.

  • Fuel Injection Problems

The fuel injection system on the 7.3 L Power Stroke can also be troublesome. Many times the injectors will become clogged and need to be cleaned or replaced altogether.

This can cause a number of problems for your engine and can even lead to a complete replacement. Sometimes, if the injectors become clogged, the fuel will back up into the cylinders and cause them to seize. Then, in turn, it wreaks havoc on the transmission because all of the oil is released when this happens.

  • Head Gasket Failure Due To Low Oil Level

A common problem among many diesel engines is head gasket failure due to low oil levels or using substandard oils that are not approved by manufacturers of these engines. This causes overheating of the engine due to the lack of lubrication and can result in complete failure of the engine.

To prevent this, you should always ensure that the oil level is at the proper level before starting your vehicle. To do so, simply wait until hot idle (approximately 15 minutes), open the hood and remove the dipstick with a clean rag to keep dirt off of it. Be sure to wipe all oil from it first as well as rotating it slightly if there is any question as to whether or not a good amount of oil has been present previously.

If you do experience any issues with your 7.3L, be sure to have it diagnosed and repaired by a qualified mechanic. Trying to fix these problems yourself can often lead to even more expensive repairs down the road. Trustworthy mechanics who are familiar with the 7.3L engine will be able to quickly identify and correct any problems, so you can get back on the road without worry.
