adjusting valves on a 5.9 dodge diesel

Is there anyone who can tell me how to adjust the valves on a 5.9 diesel? The truck has 245,000 miles and never had them adjusted. Dealer wants $176 to do it.

Yea its actually really easy if you have mechanical snap. You will have to buy a set of feeler guages. You will need a .10 and .20. Get you a stubby flat head screw driver for #5 and #6. Get a barring tool, and the instructions. We had to bend a flat head to make a stubby to get our last sets.

I figured that since he's posting in the 12 valve forum and his user name is dragster1995 that he has a 12 valve.
Always thought the 24 had self adjusting valves.

Well guys its a 1996 and I have never worked on a diesel before and I dont have any of the specialty tools for it. I believe it is a 12 valve.

That's a 12 valve. Your best bet is to get the factory service manual. It has how to adjust the valves as well as a host of other things. Especially the wiring diagrams. I think the best price is at Dodge Cummins and Ford Power Stroke Diesel Truck Accessories - Geno's Garage It will save you a lot of money in the long run having the real service manual rather than a cheapo aftermarket version.

176.00 seems kinda pricey since it only takes about an hour to do it.

Yes I thought it is pricy. I am also trying to find info on setting the timing as well so if anyone can help there too. Dealer wants $96.00 hr. to do that as well they say will take about 2-hrs.

That would be a good price considering the tools to set timing will cost you about the same. Hardly worth buying the tools if you're only going to do it once plus the dealer usually won't set your timing at anything except stock, it's illegal.
You want your timing at 15-16 for the best fuel economy and power.
