Adjusting Valves

[Prairie Dog]

The manual that came with my truck indicates 150,000 miles for the first adjustment but doesn't say anything about an interval after that.

NOTE: To obtain accurate readings, valve lash measurements AND adjustments should only be performed when the engine coolant temperature is less than 60° C (140° F).
The 24–valve overhead system is a “low-maintenance” design. Routine adjustments are no longer necessary, however, measurement should still take place when troubleshooting performance problems, or upon completion of a repair that includes removal and installation of the valve train components or injectors.


IMHO, it doesn't take much to do, so maybe every 100,000 or if you want to 50,000

Kinda funny... I called a few places for the hell of it to see about an valve adjustment for my year, 2005... .
1. A diesel shop... . 4 hours ..... $320 plus gasket which is about $80= total 400 plus tax

Gulf Coast Dodge and Jeep... . 3hrs... . $315 plus tax includes gasket

Hill Kelly Dodge..... 2 1/2 hrs... . 250 plus gasket which is over 100 cause it has wires in it, plus tax.

Cant imagine that it takes 3-4 hours to unhook a battery, remove 6-8 bolts, wiggle a few valve, bar engine over if needed, adjust 3 sets, bar engine over again, adjust 3 sets and put the valve cover back on (gasket is reusable) and hook up battery's... ... . screw them, I bought the barring over tool (40bucks) from Genos and since I have the service manual, I'm going to be a valve adjustment expert. Only other thing I dont have is a torque wrench which I will soon!! It may take me 2 hours but I'm worth 250 bucks and I wont charge my self and environmental fee either!!

rock on

I need to look it up but I can remember the service manual saying there isnt a set mileage to do a valve adjustment. It should be done only if there is a performance issue. If I get time I will try to find it. I had 224,000 miles on my engine and the valve cover had never been off, all the valves were within spec.

incorrect for any year CTD
