Although presented nicely, this info is a derivative of the info available in the diesel tech libraries. It has been available for years. They are titled "The 6.? Bible". Insert your engine type where the ? is. There is a version already published for the new 6.7 Ford diesel. I rarely read the diesel mags. Their information, while often correct, is way behind the knowledge curve. An example would be the last editions of both rags had articles on the egr cooler/oil cooler issues that plague the 6.0 series engine. Both articles rely heavily on a paid advertisers products and expertise to write them. Hardly unbiased reporting, but it is informative. The problem is the information is almost 2 years old. The egr cooler/oil cooler problems have been discussed at length on all the Ford Diesel forums. The cures have even been posted here. JMHO YMMV
