2nd Generation Dodge 24 Valve Powertrain

This is a discussion forum of the 1998.5 to 2002 2nd Generation Dodge Ram Trucks with 5.9L Cummins 24 Valve Turbo Diesel power train and drive line system. This includes all sub-system including wiring, fuel, oil, exhaust, air, transmission, computers and sensors.

  1. seeing that surging can be an issue would putting my sensor in the air dog sensor hole location be a good idea? or would this be to far back? mine is located under the drivers door on the frame.

    The headlights on my truck are not bright as they should be. What would be the best way to do this. Would LED bulbs be better? If so what all would I have to do to make this work? Just replace the bulbs or is there more involved? Is there other options that I can use? Any ideas would be appreciated .

    If this is not posted in the correct place please let me know. Today i started tearing down my truck to replace the tappet cover gasket and check for the KDP. When i pulled the rubber hose from the crankcase breather i found the nipple is broken. It has a big chunk gone. I cant see paying $100 for this thing. If anyone has one sitting around not being used that they want to sell please let me know a price with shipping to Kentucky, zip code 40216. Thanks in advance for any help.

    So trans and tcase is in the truck and i got it to move this past weekend outside the shop. YAY, well right after I rebuilt it I tested operation and it worked, now after it setting awhile then finally getting put in, it works but only in one gear, I dont remember off the top of my head if it was 4x4 high or 4x4 low but definitely 4x4. Im guessing something got seized inside form it setting and me not being proactive and moving the gears ever so often to prevent this... So with it installed and fluid in it, i guess i can just keep trying to rock it back and forth and hopefully it frees up? i did see the 4x4 indicator switch sometime seizes up to so i might remove that asw…

  6. Are Napa map sensors any good? My truck has been thru 3 Napa map sensors in the last 4 months. I’m wondering if they’rs a deeper issue? I have noticed lately that my truck is not running well and don’t sound at all like other 24 valves around. It idles rougher and overall sounds way different. Valve lash is good fuel pressure is good. I have a set of stock injectors I’m putting in soon and I may replumb the entire fuel system as I’m wondering about air in fuel. What you guys think? I’m getting very fed up with how it runs.

    I’ve been having some minor OD/lockup quirks start showing up lately so figured I would start with an AC test. With truck at idle and minimal electrical load I got 0.053v between battery ground and alternator charge post. Then I decided to turn as much stuff in as I could (max a/c, high beam lights, mirror heaters, etc...) on the test also at idle speed I got 0.1xx volts with constant up and down fluctuation. So safe to assume that I have diode problems in my alternator likely causing my OD/lockup problems??? The alternator is only about 5000 miles old and functioning fine so I was thinking I would just install new diode and do the w-…

    Hi I have a 2001 sport 4x4 Cummins. Just put a early 47re in with a dpc billet single disc tc, deep pan, and I did a trans go shift kit. Not the Torque converter won’t unlock I’ve changed all of the electronics in the tranny and pulled the valve body back apart and have found nothing wrong why is it still doing this???

    I know this question has been asked in the past but I couldn't find the info. I have a 1999 Dodge Ram Cummins 2500 5 speed and to engage gears the pedal has to be pressed into the floorboard carpet. I have tried to sell this truck without any takers. There is over $10,000 in parts and labor above the price I paid for it. I have about $4K and my brother when he owned it put another $6k in it. Some of the costs in parts was not needed at all, Turbo rebuilt by Mid-West Turbo when nothing was wrong with it, Fluidamper added, Hi-Torque starter, Ceramic disc brakes and so on when good stock parts are more than good enough for a 20 year old ride. My brother is not a diesel mecha…

    Does the head end of fuel injector line have some type of Teflon grommet or is a metal to metal contact. Could I clean up the cross over tubes and replace the o-rings and re-use them. I cleaned up cross over tube for #1 cylinder. It is pitted.

    Ok first time posting on a forum so if I put this in the wrong category..beat me accordingly. Btw, this site has been Awesome in helping me sort out updates & upgrades for my 99 so Big Thank you to all that contribute. 4th gen 2500 OEM 18" wheels fit a 2nd gen 2500? From what I have read thus far, yes they will. Only 1 issue & that being the axle being out about an inch or so farther on the Gen2. 2" spacers on rear only apparently remedy that. 4th gen tires are 275/70/R18 I have 20" on mine now, but am wanting to downsize just a little. I did find a pic of someone that just recently put the very wheel combo I am wanting to buy on his 1998 with th…

    Good day everyone, Have a few questions regarding rear main seal replacement. 1. Do I need the $200 tool to install the seal? 2. What kitsch have you guys used to not need the tool? I have to replace my seal, but don't want to have to dish out extra money for a tool I may use 1-2 times. Thanks, Tim

  17. Hi folks. I am interested in settling on the right fuel transfer pump for my 1998.5 24V 2500. My engine is stock. I have no plans to increase horsepower or torque. I have 157,200 miles. I bought the truck last August. Right before I bought it, the VP44 had failed and been replaced in June. However the lift pump was not replaced. I decided to dig in a learn a bit about this known problem. I purchased a fuel pressure test gauge and checked the stock Carter pump. Readings were ok for the stock system, but a little down. I decided to change it out ASAP with another stock Carter pump at that time. I wanted to experiment and track some results. With the new Carter in I was…

Cleaned all of my grounds again made sure everything was hooked up .checked over the wiring a few times im clueless now, im not good at electrical diagnostics, any idea of where to …
