I run Beck Arnley on my truck. I learned of the downfall of MOOG as I shopped for ball joint service on my truck. I then put two & two together and realized why the MOOG's never lasted on my old F150. The "Problem Solver" series of MOOG parts manufacturing methodology (low cost "almost" MOOG parts) trickled into the mainstream manufacturing Moog processes (cost savings efforts), thus screwing the pooch...

 

This needs to be sticky.

 

Great write up. Thank you for the time and effort.

 

Its added as a link to our tech folder

 

Thanks boss.... I am new enough to really appreciate the work that went into this and the value of this as a single source "must read". Jus lookin out for the new guy.

 

In addition to what's already been posted in regards to head gaskets, I also recommend regular change of fuel filters, depending on use of vehicle(no more than 15K). Also, use only Motorcraft filters, as aftermarket filters can lead to driveability issues and or costly repairs. Ensure HFCM is obtaining proper pressure, measured at secondary filter housing. Also, inspection of check valves inside banjo bolts on heads can be helpful. Finally, the cetane booster available at any Diesel Ford Dealer, will optimize the quality of your fuel, lengthening life of engine parts.

 

FordWrench, you work at a dealer? Sounds like it. I have mine service done at my dealer. As good a deal as anyone around and I trust them. People from 50 miles away or more bring their diesels in for work, especially ambulance services. I also use the cetane boosters/treatment I get there.

 

Was this a misprint?? Oil at 400 degrees????

GREAT write up though!!

 

6L PWR - THANKS!! The oil temp alarm point was meant to be recommended at 240. The engine begins to defuel at 254. I did a lot of cutting and pasting to get this to allow me to post, so no telling how that got there. All comments are extremely welcome. Above all things I want this post to be as accurate as possible.

I wonder if the administrator can give me access to correct this one in the original post ????

 

Great info.

 

In addition to the basic tips in this thread, I just wanted to offer more detail to those folks that are interested.

In case you haven't already seen it, just post your email address on the last page at the end of the thread linked below:

You can also send me your email address in a PM or visitors message.

Both of these threads are fairly old, but there seem to be quite a few new owners who have found good deals on 6.0L's.

 

I have a 2004 and my oil temp gauge has went up to 260 on hard climbs pulling my fifth-wheel. When I took it to dealer he said that was ok for short periods. He also told me the truck would start to defuel at 280. He said this would show up on my computer and to bring it in if that happened as my oil cooler is under warrenty???

 

The engine begins to defuel at 253 degrees (PC-ED manual - see below). You seem to have a problem (perhaps plugged oil cooler) or you have a bad aftermarket gauge. Ask the dealer to show you where it says that defuels at 280. It may just be you need to find another dealership.


Fueling Corrections
The PCM adjusts the injector output based on the oil temperature information received from the
engine oil temperature (EOT) sensor and turbo boost information received from the manifold
absolute pressure (MAP) sensor and the barometric pressure (BARO) sensor. These corrections
are necessary to meet emissions requirements and to optimize power. The engine coolant
temperature (ECT) and the EOT sensors are used as the primary input to the PCM to enable
adaptive cooling. This provides a means of providing adequate cooling in severe engine
temperature conditions. When the ECT is greater than 105°C (221°F) or the EOT is greater than
123°C (253°F), the fueling rate of the engine is modified to provide cooling protection and prevent
engine damage due to overheating. Outputs of these sensors can be monitored using a diagnostic
tool reading PIDs.

Also - Your problem really should be posted in a new thread. I would like for this one to be on the topic of "preventing problems"

thanks!

 

Just wanted to add a link to the recent Diesel Power Magazine article:

bump - seems like quite a few new members and 6.0L owners.
