Getting Stoked to Service the 6.0L Power Stroke
If there were one engine that plagues the mid-size diesel world, you would have to say that it is the 6.0L Power Stroke. The 6.0L came into existence because the EPA demanded tighter emissions laws for diesel engines. Even though the 7.3L was branded as the reliable workhorse for Ford, it would never be able to pass the tighter emissions laws that were going to come into effect for 2004.
Service Solutions: The ‘CKP’ Script
The signal of the position or rotation speed of the crankshaft position sensor (CKP) contains a lot of information about the engine. When the engine is operating, the engine cylinders push on the crankshaft journal. This is why the crankshaft briefly accelerates after top dead center (TDC) on the expansion (or combustion) stroke. If the fuel did not ignite in the cylinder there would no acceleration.
Clean Diesel Surge Offers Diagnostic and Repair Opportunities for the Aftermarket
There’s a bright future for the latest generation of clean diesel cars and trucks, thanks to common rail high-pressure, direct-injection systems with sophisticated electronic controls that have transformed today’s diesels into clean-running, quiet and powerful power plants. As these vehicles come out of warranty, it will create new diagnostic and repair opportunities for the aftermarket.
Diesel Engine Glow Plugs: Not Just For Starting Anymore
Since diesel engines ignite by using the heat of combustion, they usually need help when the climate changes to the cold of winter.

The DeLorean – Back From the Past Part II
This article explores performance modifications that have been developed for the DeLorean from the time of its release to the present day. Although anything is possible, performance modifications over the past 30 years have focused primarily on the areas of engine modification (or replacement), and suspension modifications. I won’t be getting into time travel modifications – those are beyond the scope of this article.

Tech Tip: Ford 7.3L Powerstroke ‘Cackle’ (Noisy) Injector
Some vehicles may experience a misfire or “cackle.” The injectors in the 7.3L diesel run off of the high-pressure engine oil pump. The number 8 injector is the farthest away from the oil pump, causing a filling problem, which may result in a misfire. Ford replaced the number 8 injector in some vehicles as needed with a different injector to solve the problem.
Tech Tip: Exhaust Restriction Leads to Turbo Destruction
Turbos in gasoline applications operate at extremely high temperatures and RPM. If the exhaust stream, including the catalytic converter, is even partially blocked, the increase in exhaust backpressure can lead to thrust bearing failure.
