Anybody know where I can get the procedure to adjust the valves on my 12 valve? I heard there is a special tool for the 24 valve, is it the same for a 12?

 

Try this- http://dodgeram.org/tech/dsl/valve_adj/12_valve.html

No special tools unless you want a fancy $33 Cummins feeler gauge holder.

Barring tool is nice but turning the alternator pulley nut works just as well.

 

No specail tools needed to set the valves just need to now the setting order and the lash settings

 

Why does that link say not to use the gray gaskets? Those are the gaskets I bought. Will they not seal properly?

 

Are they Cummins gaskets. I use the gray cummins gaskets have had no problems with leaks. Also replace the o-rings on top of the valve covers were the hold down bolt goes threw.

 

Yes they are Cummins gaskets but I do not have the o-rings. Can I get them at a parts store or do I have to go to Dodge?

 

You could by the o-rings at a auto parts store, they just have to fit tight on the valve cover hold down bolts. I don't know of any problem with the gray gaskets, i have done a ton of valve sets and have used them with out any leaks.

 

Is there any reason not to use this way to adjust the valves,it seems like the easiest way they have listed on there.


A short version:

Let the engine cool 4 hours and remove the valve covers.
Use the alternator bolt to turn the engine backwards.
When a rocker arm is not on the lift lobe of the cam, adjust the intake valves for 0.010" clearance and the exhaust valves for 0.020".
Loosen the lock nut
Adjust for the correct clearance - a slight drag will be felt on the feeler gauge
Torque the locknut to 18 ft-lb.
Recheck the clearance - the drag on the gauge should be the same.
Continue turning the engine and adjusting valves until all have been completed (put a small plastic sandwich bag on each valve when it has been done).
When adjustment has been completed, remove the plastic bags from the valves and replace the valve covers
