6.0L Power Stroke Engine Overview

The 6.0L Power Stroke came into being in response to the stricterNOx emissions standardsthat were being put into place for diesels. It was realized that the only way to meet these requirements was to release a new engine platform.

Unfortunately, with Ford pushing to get this engine out quickly, there were certain issues that arose. The first engines experienced glitches with the injection system due to problems in the software. This resulted in complications with emergency vehicles using the new 6.0 and lawsuits were filed against Ford.

The6.0LPower Stroke made use of several pieces of new emissions control equipment and a new variable geometry turbo. This helped to boost the power up to 325 hp and 570 pound-feet of torque. Certain parts were prone to failure, however, including the oil cooler, EGR cooler, and high-pressure oil pump, among others. There was a resultant perception of the engine as being unreliable, which impacted its reputation. Ford ultimately abandoned it in 2007.

Specs & Attributes of the 6.0L Diesel Engine

The 6.0L was a more compact engine than the 7.3L, with both the oil cooler and high-pressure oil pump integrated into the block. The gear train for the crankshaft, camshaft, and high-pressure oil pump were moved to the back of the engine. It featured an exhaust gas recirculation (EGR) system, along with four-valve cylinder heads, a quick-spooling variable geometry turbocharger, and a fuel injection system with hydraulically actuated electronically controlled unit injectors (HEUI).

While the 6.0L had some serious issues, towing was not one of them. The towing capacity varied by model, year, cab size, and box length, but ranged from a conventional 12,500 pounds to 19,200 pounds.

Despite the various issues experienced by the 6.0L, enthusiasts have been able to push it to remarkable heights, with guides available online detailing how to add an additional 300 hp, and when you see Diesel Power Challenge competitorJesse Warren push his 6.0L up to 1,758 hp and 2,532 pound-feet of torque, you know that the engine is a viable platform to work with.

Common Issues With the 6.0L Power Stroke

As much as the7.3L Power Strokeis known for durability, the 6.0L seems known for various problems. Some of the common issues included:

Exhaust Manifolds

Factoryexhaust manifoldsare prone to cracking and warping often breaking studs and resulting exhaust leaks. Upgrading your exhaust manifolds and up-pipes will lead to increased reliability and performance.

Oil Cooler Faults

This is the most commonly reported problem with the 6.0L. The purpose of theoilcooler is to lower the engine oil temperature, but it could become clogged or restricted with few warning signs. Silicone sandleft behind from manufacturingcould cause buildup and restrictions in the coolant system. The oil temperature, if too high, could cause gaskets and O-rings to fail. Checking for these issues should be a standard part of all routine maintenance.

Exhaust Gas Recirculation (ERG) Cooler Problems

These issues seem to be more common in the 2003 model year. This clean emissions component is intended to cool exhaust gas which is recirculated back into intake manifolds. However, soot buildup left the EGR coolers and EGR valves prone to failure.Sometimes this resulted in cracks, leading to coolant entering the engine. If this is severe it could causehydro-lock and result in major damage to the engine.

Fuel Injectors

The6.0L Power Stroke fuel injection systemusessplit shot electronic unit injectorswhich deliver fuel to the cylinders. Unfortunately, the injectors do not operate well with poor fuel and oil quality. Dirty oil, low fuel pressure, electrical issues, and mechanical failures can all cause the fuel injectors to fail.

TheFuel Injection Control Module(FICM), which calculates the start of injection and injector duration and is responsible for precise injection can suffer slow deterioration,due to low battery voltage. In fact, it may go unnoticed long enough that by the time you are aware of an issue, it’s often too late.

High-Pressure Oil Pump (HPOP)

Operating with very high pressure, the fuel injection systems may experience internal engine leaks as the O-rings deteriorate. When the engine is hot, this may result in hard starts, no starts, or loss of power.

Turbocharger Problems

A variable geometry turbocharger was designed to reduce turbo lag and create a better throttle response. Carbon or rust may build up in the vanes causing themto stick, leading toan over-boost or no-boost condition.

Head Gaskets

There are 4 torque-to-yield (TTY) cylinderheadbolts per cylinder, each with precise clamping force, but certain circ*mstances can cause the bolts to stretch and lose that clamping force. These bolts are a significant problem that could lead to a blownheadgasket.
