I have read two of the 6.0 PSD commonizaion threads and have learned a lot about the changes for this engine. The information states that engines made after Jan. 11, 2006 are considered to be of the commonization version. My questions are: If I buy a truck that has a build date of February 2006 will it have the latest engine? If not what build date for the truck should I settle for to get one of the most trouble free engines? Is there an engine serial number break point that I can look for and what is it? Can you find this serial number by just knowing the VIN?

Thanks,
Heavy Tow

 

It would be nice if someone had that information. But until then, you can check the engine build date by looking at the sticker on the FICM module on the engine. That is probably a better engine reference than the truck assembly date.

 

In the "For What It's Worth" department, My 2007 truck's build date was late November, 2006; the engine build date was in July, 2006.

A truck built in Feb of 2006 would probably have a pre-commonization engine.

Truck and engine build dates seldom are the same. The date the engine was built will be on the engine itself. That is the date I would use to determine if it is a commonization engine or not.

 

Here is another chart, if you like charts

 

Excellent. Reps coming your way.

 

Ask and you shall receive! Maxium the chart was just the ticket. It will give myself and anyone else the info needed to know where they stand on the commonized engine issue. I am currently on the hunt for an F350 and want to be sure I get the better of engines when I buy. As stated in early posts by other members just knowing the truck build date doesn't tell the whole story. Thanks again for the help.

 

Please help my ignorance. Where should I look for the engine serial number on the engine? Also, where is the FICM located? I am disabled and climbing around and over the engine is hard on me. Thanks.

 

The serial number and date of engine build will be found on a label on the FICM module. The FICM module is above the drivers side valve cover.

 

Thanks for the help.

I added some info on this in a new thread. See:

OK, I'll guess I'll be the one to ask the stupid question...

What is the difference between the pre and post comminization engines? I guess by the comments that the post engines are somehow better.

I have an '06 but bought it in 11/05 so I guess I have the pre engine which has been bullet proof so far.

Thanks Mark.
It looks like the comminization engines have slightly larger bolts in certain areas and an improved rocker assembly so they should be "better"
