F5, There are small white sticky bar coded labels all over the truck, hidden away in the dash, and on parts of the chasis indicating the date and various times for different items. One example wasn't really secured so I pulled it off and kept it in my file for reference.
It says, " D8X 00503671 3/27/2006 12:41:32 PM Commodity: Steering Column" .
I am guessing that this was the Build date for my truck, and the various times indicate when that componnent was installed on the line?
Based on this, I must have an old style head. Should this be a concern? Is the problem wide enough spread that there may be a recall for the '06 Heads?
