2nd Generation Dodge 24 Valve Powertrain

A while back I posted some concerns about how long an OEM muffler would last on the OEM exhaust system. I was mainly concerned if back pressure could be an issue as the muffler aged. I never really did get a definitive answer, probably because most people had moved up to 4" and 5" exhaust systems from the turbo back with either an aftermarket muffler, or no muffler at all. So, I decided to do a little research on my own. I found a general statement that indicates Cummins does not want to see any exhaust back pressure above 3 psi. I connected a gauge to the 1/8" port on the exhaust elbow and strapped the gauge onto my windshield wipers and then went on a …

When my truck is plugged in and has sat all weekend, it will fire right up. I went to leave work today, the wts light ran for a normal amount of time but the truck fired for a second and died. It did that 3 times, the 4th time it fired up and ran a tad rough for a moment and then smoothed right out. I figured if I was losing fuel prime it would do that all the time, especially when sitting for extended periods.

Coming into Rainier this morning the truck wouldn't idle down and I was heading for Castle Rock and then the truck hiccuped and backfired at exit 46 so I turned around to head home and now it went into complete limp mode only partial throttle and then now no throttle and the code is saying ECM failure. I disconnected my adrenaline and tried running the truck and it has the same code and it still has no throttle. Now I'm stuck by tractor supply in kelso waiting for AAA to take me home. I just had a local shop in Scappoose install a rebuilt engine about 500 miles ago and I'm sure there's is a total coincidence that this is happening now but it's just one thing after anothe…

20 years ago or how ever long ago, long time. I started running 2 stroke oil after reading Michael's research and never looked back. I keep hearing this Archoil lubricant and wanted to see if there was any talk about it. I cant seem to find the write up on it from years ago. So Im here picking brains on the subject. What do y'all know?

I am in the throes of replacing the crank seal, tappet cover gasket, radiator, and intercooler. With the good access, and since I plan to keep this truck, I figured I'd replace the battery cables. No real issue just tired of the corrosion and poor stock terminals. I ordered a nice pair from K Suspension but the install instructions leave a lot to be desired. Information is limited from other sources, anyone every tackled this job? One part that seems daunting is the many sensors that share the wire loom with the power cable going to the starter. Getting that apart and keeping it all straight must be a challenge. Any advice is appreciated. 2001 2500 Quad Cab …

I have my injection pump off and have to replace the bracket. Is it true the vacuum and power steering pumps can be removed when the vp is also out? I’m worried about timing gears falling out of place thanks

200℉ Cummins ThermostatI've been experimenting with hotter coolant temperatures and found for most daily drivers this is a good way to go. The added heat actually will improve the MPG number just slightly and reduce EGT's slightly. Gates - 34212 - 200℉This is direct replacement number. It will fit into your 1998.5 to 2002 Dodge Ram Cummins 5.9L engine without any modifications. ResultsSummer operation floats right around 204 to 210℉ coolant temperatures. With the tuning I've done on Quadzilla the engine oil temperature will stay 30 to 35℉ cooler than coolant. This stays the same for even wintertime operations with no issues so far in one year of operation even towing. In …

2001 ram 3500.. edge comp/smarty .. So been having a problem with a stutter under throttle .. 3/4 ish throttle.. I re adjusted the factory made no difference and tps% was reading 8% at idle 77% wide open .. I ordered a timbo which I think is a rip off but anyways.. installed it now it want read below 13% throttle at idle .. I removed it from bell crank to make sure and still 13%.. so I installed it and when I did the adjustment procedure.. I had to move the idle screw in all way to the bottom to get it to move and now my throttle is around 1/2 way.. yes its int the range it called for 580-700 its at .666 and I moved till it voltage came up and then turned back to vol…

Id like to install a battery disconnect that is easily accessible 99 3500 4x4 cummins auto. Any suggestions appreciated.

So I was changing the tune in my 2000 when the smarty cable got disconnected. Now I keep getting "error comm time out" when it tries to restore it to stock tune. Is the ECM toasted?

I have a leak in the front of the engine it's right by the slobber tube but has gone from sitting a week and leaving one drop no bigger than a penny to leaving that overnight. It appears to increase while running the engine, sometimes... pictures explain more it's got enough oil everywhere that I will have to clean it up somehow to even figure out what is leaking... When I replaced the body I cleaned as much as I could around the slobber tube but 340,00ish miles causes quite a caked on mess that needs to be cleaned. Questions are what would be leaking in there front crank seal or cam seal? If I have to replace either how hard is it I'm extremely busy so i…

I recently bought a new to me 1999 2500. Low miles, 124k. My issue I'm having is I have codes p1964, no ccd bus and the companion code. I have no wait to start or an intermittent wait to start. What I have found weird is if I unhook my grounds for 5-10 mins then reconnect them the wait to start is immediate for 3-4 key cycles, then goes back to intermittent or not at all. I found this out when I put on new military cable ends, the grounds wouldn't stay tight. Pickup runs fine, doesn't want to start when it's super cold, which makes sense with no wait to start but when it's warm it pops right off and runs great. Also another side note I have had it…

I’ve had my fuel boss on for years. No issues other then replacing dried out cracked rubber fuel lines over time. I want to delete my oem fuel filter and run a frame mounted setup like GDP’s stand alone filter w/ heater. By using a FS19596 filter I can have a connection for the oem wif sensor. I also want to delete the oem electric lift pump. Has anyone here bypassed the stock lift pump and ran straight mechanical? And if so how did you plumb it? Im thinking 3/8” line from tank to filter, then to mech. pump then to VP44. But I need to regulate the pressure with the bypass valve so should I tee it from the return side up to the vp? The r…

So my stock exhaust manifold on my 2000 cracked the other day. I have a 98 with a cracked block that I'm robbing the manifold from. The one I'm robbing is a 3 piece ATS. Problem is, ATS manifold has 4 studs in it, while the stock turbo has 2 studs in it. Which one would you guys drill out the holes on to get them to mate together? I'm not ready yet to put the compounds from the donor truck on my 2000 yet.

First, and foremost, I was inspired to perform this modification by @Mace (a new member with lots of knowledge) who provided the idea - I never would have thought to do it on my own. I also want to thank him for providing the "how to do it " information as well as a list of parts. Well, I am finished, but I didn't do it the way Mace from Kamloops did it and in no way is my modification any better that what Mace did - in fact, some may prefer his modification over mine. After much of going this way and then that way and then repeating myself, I just finally came to a stand still. So, I stopped working and started thinking about what I really wa…

Oil pressure gauge has intermittently been working for the past couple days, been working on start up then I'll start driving and it will randomly drop then come back alive. Seems like it likes to drop out more so when I come to a stop and the truck is idling with lower oil pressure. When I'm cruising and have like 40 psi it usually stays alive. If I come to a stop and it does while I'm sitting there idling I can rev and hold it at like 1100 then it magically comes back alive on the dash. Is this most likely the oil pressure sensor? Or could it be a bad ground somewhere? Sitting idling right now and it's jumping back and fourth check gauges light will come on it will drop…

I'm working on my VP44 and ECM projects and need to know how much fuel is actually injected by the injection pump. This is so I can calculate a fuel rate in milli Liters for determining engine load and also for the overhead trip, mileage display computer. So i dug out my old VP44 core and did some measurements. I thought I would share what I found and get some confirmation or feedback. This is a SO pump with three injection plungers they are 7.3 mm diameter. The cam donut has a thickness of 10.5 mm at the maximum inward point and a thickness of 7.1 mm at the maximum outward point. So 10.5 - 7.1 = 3.4 mm of stroke. I don't have an ultra pr…

What are my options for upgrading rear end to posi? 2001 4wd 2500

So I've been hearing some chatter while coasting on the highway, i initially thought I was just in need of a valve adjustment because it sounds so similar to chattery valves I've heard on other engines. Did a valve adjustment and the noise is still present. After some long drives on the highway I realized if I'm coasting and put the slightest bit of pressure on the clutch the noise goes away. And when I say slight I mean slight, you could lean and empty sneaker or work boot on the pedal and the noise dissapears. I also noticed if I'm coasting and press the clutch pedal in and let it out the noise is gone for 5 seconds or so then returns. There's no noise if I coast for a …

I’m new here. But saying that I want to pass some info on to members about the 24v apps that should not be overlooked. Cummins does NOT make the apps for our trucks. They don’t even sell them. It’s the responsibility of the oem to make a control apparatus for their engines. Cummins makes engines not control mechanisms. The correct apps for our trucks is the Williams Control (WC) 131973. Holdwell makes the jumper harness to go to the Duetsch connector on the ISB engine harness. The amount of fake ones available online is staggering. If their name isn’t on the sensor or it’s blank it’s counterfeit. So, if you got a “Timbo” it’s j…
