2nd Generation Dodge 24 Valve Powertrain

I recently picked up a 98.5 2500 2x4 short bed that had some money thrown at. I decided to take it to the next level and do everything possible to get 30 MPG when empty at 65 mph. I live in a 5th wheel camper and travel for a living, so diesel costs add up! Please give me your best ideas to improve MPG. Here is what I've done so far. Front End Aerodynamics on the grill & lower bumper shroud & tonneau cover ( Considering a belly pan underneath ) RV 275 Injectors with 7 holes ( Are there better injectors out there for economy ? ) 19.5" rims running 245/70 tires that leave me at about 1750 RPM @ 65 mph with 3.55 gears ( Will experiment with smaller stock for less …

My clutch of 7 years decided to peace out today (throw out is just screaming). 1 month short of my trans rebuild slated for end of June (of course). I bought a Valair DD quiet clutch kit 2 weeks ago and I have South Bend hydros already (clutch is a single disc SB) I need to pull my bellhousing adapter plate off to reseal my rear cam plug. Does anyone know the torque spec for the bolts that mount it to the back of the block? Because it’s DC I can’t simply log into QSOL and find it by ESN. Gonna do my rear main seal too (sleeved style). I found a NOS Cummins installer for that particular seal for cheap online so I know have just about every tool for the 24V one can think…

I have always had a manual on all of my 2nd gen cummins trucks, mainly due to the obvious reason's we all know with dodge transmissions, to include failure, reliability, strength, and PRICE (auto), especially when you add any power to it. So now I am trying to do a crash course on auto transmission in 2nd gens cause I am clueless on everything/anything with them. Man this is making me feel so dumb... Gonna be trying to learn about lockup, torque converter stall, billet this and billet that, what auto parts, auto computers or tuners?, etc... I am so so so tempted to put a nv4500 in this build, just for the availability and strength! Please reference 24v 1500 Cummins Thr…

Just a teaser of what’s to come. I designed this and just received it in the mail yesterday. I had an engine fan manufacturer make this to my specs and after some future test fitting and such I hope it to be available for everyone who wants one. After I’m sure it works I’ll make a post about how to get one and what needs to be done to make it work (i.e. does it work with a Fluidampr? etc etc) I do this for the advancement of our 2nd gen community. I will not make a penny on this. I imagine my design would be stolen and copied once they’re available on the market but alas, it is life. Stay tuned…

Can i replace the 95gph motor with a 165gph. Its only like 12 bucks more. Fass is closed but id like to order a motor tonight this one sounds kinda like the transmission with rocks in it. I was cruising home today in 5th at 70 trucked buck so im thinking you peice of ****. Put it in 4th and stood on it cause im thinking you freaking pos trans. Pushing throttle only made it buck and studder. Verifued **** i got no fuel and made it home to mtn home going 60 in fith. Truck stumbling pulling all the steep grades to mtn home. Ughhhh ever werk so far having this truck is something. I did back on pump motor with a rachet and that only made it shut completly off. I do have…

Good afternoon, I put a titanium fass lift pump along with a Fleece sureflo sending unit on my 2001 pickup about a year and a half ago. It’s been flawless for a few thousand miles. I had been noticing some slow starts when warm. Not bad just a few more revolutions than what was normal. I put some NAPA cross referenced fuel filters on because I didn’t have FASS replacements and didn’t have the time to wait . I started to take a trip recently and fuel pressure dropped significantly. I got the truck home and parked it for a month . I wasn’t real confident about the NAPA filters so i replaced with the direct replacement FASS filters. Test drove the truck for an hour or so and…

New to this forum, but not the cummins forum. I bought this truck a month ago, turbo bearings are shot. I bought a Borg Warner K27 turbo. Truck is set up with a 4 inch down pipe with an HX40 4 3/8" Flange. I need an adapter to go from 3" inch ( stock size ) up to the 4 3/8" flange. I've called several diesel specialty shops. No luck.

Trans was making funny noise. Tore into it and discovered pieces of a gear in bottom of case. SO, where is best place to source heavy duty parts for the nv4500?

Hi there - Several different issues just started, and I'm not sure how to begin addressing these. Hoping that folks with a good understanding of the 24V can help sift through the symptoms and see to the core of the problems. Looking for help organizing and figuring out if there is an underlying root problem that's causing the other issues. Vehicle: 2001 Ram 2500, 5.9L High Output Cummins, 4x4, 292K miles. I only have about 3k miles on it myself since I bought it. Don't have a great idea of what was done to it before. As far as I can tell, the engine and powertrain are in a stock configuration. History: Until January of this year, it was always quick to start with mini…

I’ll start as simple as i can, we can expand as this thread goes on. Basically, i am familiar with the AC interference issue and have “fixed” that by following the WT tutorial. I rebuilt the transmission myself a few years ago and can’t completely rule out a valve body issue. I think a piece of debris could have made its way into the TCC plunger somehow and scored the bore it rides in, and when I rebuilt it i reused the same oil pump and valve body and torque converter. This problem didn’t show up right away and instead took a while to start happening. Ive got a quadzilla installed in the truck currently. Im experiencing a weird intermittent problem. It manifests thro…

Hi folks... A mechanic not far from me has his own Chrysler DRB3 scanner that works according to him. Its for sale very cheap. Is this of any use to me with it being hooked into Chyslers own computer. Might not be a bad thing to have once in a while. Regards Chris

So I follow Devin Henry on fb also known throughout the world as #superdarf He has TONS of videos on his second gen and lots of mods/ test from a tons of different products he has done/ tried. Some which are very interesting and informative. He has just recently added custom delivery valves into his vp44 and I thought it was interesting to share/ discuss. Anyone else ever done this mods or heard of it? If any power or throttle response etc? I highly suggest you go through his videos and check out what he has done!!! *I have no affiliation* Video Link for delivery valve lope

My truck has a Fleece SureFlo sending unit, FASS Titanium Signature Series 100G lift pump with Wix filters on it, 1/2in line from the sending unit to the injection pump (still using the factory filter canister), 3/8 return line from the T to the tank. If the truck has been sitting for a while (couple days), it'll start fine. The longer you drive it, the harder it is to restart after you stop. If you drive it a couple hours and stop for gas, you might need to bleed the #3 injector to get it to restart. It does not seem to have any problems once it's running, just trying to get it started again. It did the same thing (and left my partner stranded at the same gas stati…

Hello, I have a 2002 Dodge 2500, 5.9L 24V Cummins that’s been down for months & so far is stumping me. It has Auto trans, 4WD, & about 190k miles. As far as I know it’s all stock except for a FASS DDRP fuel pump. This is a long one, but any help or suggestions would be greatly appreciated! Truck was running fine & then died. Cranks (spins good), but no start. First thing noticed was fuel pump not running. Then also saw gauges are not working, no wait to start light, & odometer flashes a few times then displays “NO BUS”. It will connect but not communicate with a scan tool. It either displays no communication from module or circuit open (from the airbag mod…

I’m pretty sure this has been covered, but I can’t find it. So the way I understand this the alternator feed into the PDC is eliminated. There is a 140 amp fusible link between the two hot leads going into the PDC what is the purpose of this? Do I need to bring that second lead going into the PDC to the driver side battery or is this not needed?

First I am going to apologize for the length of this post but I want you to have all of the details. We purchased a used 02 24v 3500 dually just about a year ago. It had been sitting so we got it going and just did the basic services, fluids etc. my son drove it about a month and in mid September it developed a weird rough idle after warming up but no other drivability issues. Changed both fuel filters with napa units and no change about a week later the frame broke in half from rust so we parked it. Fast forward to January 26, cab and bed removed, new frame from down south, blasted and painted. truck goes all back together with all new parts, brake lines, fuel lines, sh…

Had the 3 locking tabs on my south bend hyd 1.5 break off yesterday. 2nd one its happens to. I contacted them and they are going to send a "repair bracket" which i guess pinches the master cylinder between the 2 brackets. Does anyone have a part number or link where else I could get this, need one for another truck

So I finally pulled the trigger on an adrenaline for my 2001 3500. Im after mainly better fuel economy at this point, more so than the power that is possible. Myself and @Mopar1973Man have discussed this at length and with his economy tune now installed in the quadzilla I will be doing my best to learn how to keep track of and log some milage numbers from my daily driven diesel. This little endeavor started with Mike and I discussing his milage in the up and down terrain of Idaho. Here in Northwest Ohio the terrain is very flat so the speculations of higher numbers in this area arose. Now that I have the quadzilla installed I will be trying to track my milage closer to co…

Fixed it for you. First leg down. We ran down hwy 55 figured on Emmett ID but that failed when we got there we found the RV park closed. I head down towards Eagle ID but found a Chevron with a dirt lot besides the store.I did the polite thing walked in and asked if I could park here. Gal said, "No problem.". Wife and I are going to dry camp as much as possible. Scaled the truck bit heavy 8,880 pounds, trailer getting close 8,360 pounds. Total weight 17,240 pounds. Running my custom tow tune. Level 2. Plenty of pulling power and roughly 12 MPG with the weight.

Delivery valve modification,I know at one point they were sold years ago and would like to do it to my trucks. Anyone have some info on it?
