sounds about right. Its been a bit longer than that since my last adjustment. I probably should get it done. maybe next spring when it warms up a bit. When I do that I will go to the heavier 60# springs. I don't see a high priority in getting it done every 300000 k. You kind of gettin that feeling. There are probably others that will gasp at this

You can do it yourself:

#5 & 6 are a little hard to get to but with a little patience it is no big deal.

Buy a set of new valve cover gaskets while you are at it.

For the cost of these engines , not doing maintance , then don't complain when you have problums, not any sooner than 30,000 and not any later than about 50,000 , I've rebuilt a lot of heads gas and some diesel becouse no valve adjustments , they get out of time with the burning and burn pie shapes out of the exhaust valves and with the diesels if they get to far out they can hit the pistons and bend a nother valve job. One of the symtems is a ruff idle hot or cold for getting out of adjustment .

John, you also forgot to mention the fact that adjusting the valves help with the fuel mileage too. Mine did. It also starts better when cold too.

Check out my gallery, I took some great pics when I did my adjustment. The only difference is that I don't have a timing pin (24 valve), instead I have timing marks that I had to align by sight.

Hey gang,
Does anybody have the procedure and specs for doing the valve adjustment on a 1998 24v? dodgeram.org has the 12v, but not the 24v.
Time to do mine.

The procedure is the same for the 12v and the 24v.

Check out my gallery. I put a real good description of the process with each photo. Plus there is a article in the Tech Facts section, only bad thing is it has no pictures.

Absolutey right. Only difference is a Y shaped piece of metal and an extra valve.

The first two adjustments are the most important, after the engine is broken in the adjustment will change so little that it's hardly worth doing.
If I were to write out the schedule it would be more like 30-40k, 100k then every 100k after that.
