anything after 98.5 is a 24 valve. Rob

Them 24 valvers are famous for the lift pump going bad and taking out the injector pump with it. After vehicle purchase, it would be highly adviseable to get a full set of gauges:fuel pressure, pyro, boost, and trans temp for an auto. There's lots of good fixes for the lift pump if you go search in DTR or TDR.

I believe the "53" block is a 24 valve engine, Stay far away from those. Not sure on the years.

Is it 53 or "51". Wasn't there a run of Cummins blocks cast too thin?

Just a very short run during late 98 and 99 had the "53" block syndrome. You can crawl under the truck and find the stamp in a couple of places. Stay the hell away from the 53's bad news

If you are really set on a 24V then if your budget allows try an '02. Dodge went to 4 wheel disc brakes by this year. Other than the auto trans (which can be modified to be more durable) the brakes are the weakest link.
For overall reliability you can't beat a 12V with the P-7100 injecton pump. Stick with a manual and you should have a reliable truck for a long time.

Several of the very high hp cummins are 53 blocks. I had two 53s with no problems. There have been failures yes. But probably no more than with the cavitation issue with the psd. I personally consider the 53 a nonissue. I would buy a 53 any day of the week. Some of the 12vs were 53s I think. Just to make you even more paranoid. Wonder if maddogs is a 53?
Lift pumps are an issue though. A cheap guage to check it every oil change is all a person would need. The injection pump will run a long time without it before it fails. I know this first hand. There are symptoms to the pump going out. Subtle but if you watch itll never be a problem. Just keep track of your fuel mileage. If it drops at all the pump is on its way out. I used this method on my last truck. Worked well.

Any body seriously thinking about buying a 24 valve Cummins powered Ram needs to check out this link,
http://www.turbodieselregister.com/forums/showthread.php?t=22321&page=1&pp=15
A few months ago I looked over every post (I was seriously thinking about switching my work truck over to a 24 valve). Of all the posts I didn't see anybody who had less money into there motor as I did mine (at 175K).
Any body nervous about buying a 24 valve Ram with the #53 block needs to read this link,
http://www.schoolbusfleet.com/forum/topic.asp?TOPIC_ID=7895&
After reading both posts I figured it would be hard to duplicate my good luck with my F250 with a Cummins Ram.
As a matter of fact between the F250 and Excursion there are a total of 317K miles on them which I've put 170K of the miles on and have put just under $200 into both rigs. The F250 had the turbo rebuilt at 55K miles for $100 and the X had the CPS replaced at 114K.

I don't know if its true or not but I heard Cummins was warranting the #53 block failures regardless of miles. If true they should have done it with the dowel pin failures too

We thik pretty highly of the '03 and later models.---They have the common rail fuel system---and make a LOT less noise.--so if
you want to to to a drive in and buy a hamburger---you can actually do so without turning the engine off.

The cracked Cummins article is very interesting. I've seen this with a lot of mechanics on this site, and read similar threads to that one.
Seems like the 5.9L Cummins is a wonderful diesel engine in a beefy pick-up or smaller m/d truck. It would be perfect in Ford's F-450/550 series.
Seems like once you get up into true medium duty trucks (say 25,000 & up GVWR), the problems are greater even though the power is turned down to 210HP. I've seen Birk metion this more than once and a few other mechanics who hang-out here that once you hang an air-pump on one, everything changes.

A NON ISSUE!!! Yikes. I personally had a 99' with a cracked block. A very close friend of mine also had a 99' with a cracked block. Non Issue my ASS!

I have the "53" block and have had mine pumped up its whole life and pulled the guts out of it and no crack. I really don't see much of an issue with it. If you have a choice between a 53 or non 53 I would go with the non but wouldn't really worry about it. I know guys that have 425000 miles hotshoting with the 53 block? There are some 12V 53 blocks 1998's. I would get a fuel pressure gauge for sure. If noise is an issue don't get a 24V!

Well. I guess its the ostrich syndrom. It never happened to me. So I would gladly own another. I dont keep em much past 100 anyways. Dodge has been known to warranty em if your over but not too far. The 98 99 blocks are dropping of the 5 year warranty now. I might think twice about them now. I run one 53 very hard and the other not very. The duty cycle in a pickup truck is nothing compared to the life they live in the medium duty trucks. Even though they are rated for more hp they are often rated for less torque. Hp isnt what causes damage. Torque is.
I personally havent heard or seen one go to diesel heaven locally. Believe me. I have looked. We have known about the 53 block for years. So I looked around for one. Never found one and I know a lot of people in the industry. Got friends at cummins kenworth and intl.

Any of them with disc brakes on the back (01.5 or whatever). I would personally avoid ones with 53 blocks. I think most if not all the 98.5 00's should already have new lift pumps so take it for what it's worth. You will more then likely change it again if you keep it long enough.
There are differences between the model years like no under hood insulation, visor mirrors, cup holders, block heater cords, wheel liners and on and on. Just look at around and you will see what I mean.

6.0 owners telling him to stay away from a 53. I had my laugh for the day.
Hoss's truck, HVAC's old truck, is a 53 and pushing 700 HP. Can it crack? Sure. Will it? Who knows.
24-valves are great. Lift pumps are only a $150 and 1 hour issue if you catch it soon enough, or free if it's still under warranty.

Daddy-o,
I rented an F-800 with a 5.9L 210HP for 2 weeks to run ~70 loads of fill from a construction project I built. TQ was 520. Much less than the 610 going into the pick-up. I think it all goes back to application. The 5.9L can be turned waaaayyyy the heck up in a light duty truck, because let's face it, it's rarely going to be matted or pulling enormous weight like an M/D.
Throw a 5.9L in a big school bus or M/D dump and it's a whole diff't story.

Exactly my point. 610 is a lot but the mediums have up to 660 and they live in a much, much more hostile environment.

I know alot of the MD Cummins are 275/660.

I second this opinion. The P-7100 is well known as virtually bullet-proof and can and you can increase the HP way cheap on the 12 valvers. The only thing to watch for in these is the KDP...Killer Dowell Pin. Do a search on the TDR or in Google and you'll find that. And, they are actually a bit quieter than the 24V's. I read, I think in the TDR, that Bosch was very pleased with development the 7100 pump and was actually dissapointed that Dodge needed to go with the 24V VP44(?) pump, but Dodge had to in order to meet emmissions on their trucks. Any reason NOT to go 12V?

I have a 2001.5. Love it. I did have a few bad luck things happen. But everyone dose no matter what type/manufactor you get. If you want great pulling power you can't beat the cummings. Plus, any engine parts the cummings deal will help you out with. My only big problem we I lost my trans. It was due to a flaw in the casting when it was made. I spent a few extra bucks and now have one the will handel up to 450hp. But I love the truck, it looks great, runs great, and still sounds like a deisel. That's inportant.

I'll second that.
My "dream truck" would be a mix of components, past and present from Dodge and Ford. The engine would be a late model 12V. I like the simplicity and better fuel economy of the 12Vs. Stock they aren't particularly fast, but they match my old fart driving style just fine.
