2nd Generation Dodge 24 Valve Powertrain

I've just learned that valve lash that is done wrong or in a hurry and I didn't verify my measurements can have impacts on performance, idling, and lope. Just a few days ago I figured I would just verify the lash and cold engine I was having issues getting feeler gauge to pass on a few cylinders. I ran the head again and verified all my measurements after torquing the lock nuts. Now after a few days my lope at idle is gone. Performance has improved slightly and even the MPG is up slightly. So I've got to admit this was my bad but I wanted to share my mistake to hopefully help other spot weird performance issues and check the basic things that might cause issue. …

Alright I am working through the process of creating a true instant MPG meter. In theory, I love that word, we should be able to know how much fuel is being burned. We know commanded duration, we know speed, we know rpms. Below is the rough draft #1 for my testing, I am not concerned about it being %100 accurate. So my Question is when it comes to injectors in the VP44 system. If the vp44 can produce 125mm3 of fuel per stroke in stock form, what happens when you increase injector size? Does having larger injectors mean the vp44 will produce more fuel, IE 200 mm3 of fuel? Or is the 125mm3 the vp44 is spec'd to p…

I have a '99 24-valve Cummins that recently has been having starting issues. It was taking a long time cranking to start but I got my batteries tested and one was replaced under warranty. I also cleaned the terminals at that time and it was back to starting right up usually on the second or third crank. Then about 2 or 3 weeks ago I jumped in and turned the key to get nothing from the starter at all. I popped the hood and kinda felt the main wires and tapped on the starter. Then my neighbor came and turned the key while I looked under the hood and boom, started right up. Then it was fine until two days ago I drove to the gas station and on the way there my check eng…

Is there supposed to be any type of padding or protection between the metal strap that holds fuel tank in place and the fuel tank? Front strap is held in place by a metal bracket that strap goes into. Metal bracket is bent …trying to figure out if it was bent on purpose, to prevent strap from falling off…just in case strap ever came loose or is bracket bent from road debris? Figure 14-110 in parts manual doesn’t show anything between strap and tank , but maybe some type of protection a good idea? (My old Ford had something like gunny sack material between tank and strap. I replaced with a rubber inter-tube. But tank was from late 80's with a…

I have a few extra parts laying around after upgrading my truck. I was wanting to know how much the stuff would be worth. Some of the parts are 5 speed flywheel, Hx35, 4" downpipe for Hx35, Stock lift pump, MK-10 aftermarket filter, Manifold not cracked(Missing 2 studs as I used them for new manifold), Intake horn, Intake plate, Connector tubes, BD boost fooler. I think there is maybe 1 or so more parts I'm forgetting that I have replaced.

Prior to entering the garage the truck started and ran no problem, mechical fuel gauge worked, and had 3/4 tank, truck is 2002 ram 3500 24v h.o.I've noticed over the summer the old airdog has been dying so I bought a new 95gpm fass pump. completely removed the airdog fuel lines, wiring harness, mounts and everything needed for it. Followed the instructions for the new fass install, I used a pre existing draw straw in the tank to pull fuel. installed the new fass pump, primed the system and hit the key to cycle the pump to push fuel into a bucket, ran about 3 gallons no problem, then hooked the the supply to the VP and opened valve for fuel gauge. Crack injector lines 1,3,…

If you live in a smog test area...did the state change the rules and now you don't have to get smog test anymore?

Hello, I'm certain many have changed out the Draw Straw to 1/2" but I don't seem to be finding discussion on it. Could someone please direct me to a discussion or documentation on doing it? Thanks. Leaky

Yesterday I was coming home from a trip to the hunting property. Truck was running fine and then I hit a railroad track at 60 mph, when all of a sudden the engine got loud (valves seemed to clanked louder than norma) and I lost some throttle power. I never lost total power, just the majority. I could press the pedal 2/3 of the way down but didn't have much power. If I floored it, it downshifted hard and threw the rams up, but I didn't want to run it like that so I didn't do it but once. Other than hitting the rr track pretty hard, the only thing out of the ordinary was I filled up with fuel a few hours prior. I had a quarter tank prior to refueling (water in fuel po…

My batteries have been disconnected for about a year. Anything special I have to do before I can start it? Neighbor up the way asked if I had my beast running yet. Batteries have been disconnected so long of time he thinks I need to adjust or reset something before I can start it or run right? I asked him what the something was and I think he said APS or ATS? Guess I screwed up again...what do I need to do. Thanks

I remember someone here who had one of these and some seemed interested in them. Then I stumbled on the this today if anyone is interested. https://www.hoeslidiesel.com/collections/1998-5-2002-cummins-24-valve/products/cast-aluminum-valve-cover

The issue I'm having has been going on for about 2 months now. Started out as a bad valve body. Pull the truck down in gear it would **** off I replaced the VB with a revmax HD and a triple disc converter with a low stall. Fixed that issue. But then about a week after while cleaning and prepping for paint I lost all power with symptoms of limp mode. Did some looking and codes led to low 5 v supply. Probes the wire and walls no 5v reference from the ecm. My question is is there anywhere else on the harness I can get a 5 volt feed to run to the map and iat to see if it fixed the problem before dropping the money on a new ecm. The truck spins over more now then it used…

I don't belive my wastegate is operating properly and I'm looking at replacing the actuator. Now for the rookie questions. Should I go for the stock replacement rated to 21psi boost or spend the money on an AFE rated to 40 psi? And . How much more boost can the stock motor with 150,000 mi take?

Hi everyone I'm trying to sort out an fueling issue that is making me too scared to drive . I put a nice fresh engine in my "00 and I'm getting a pile of white smoke at idle and 1/4 throttle. It also sounds as if I have air in the injector lines at idle. The vp44 is one off my old engine with a p0216 code so I'm wondering if it's an injector that is damaged or if the vp is having problems fueling 150hp sticks? I'm new to the Moparman site but I'm very impressed by this community thanks for the info and your time!

Another Cummins with a plugged radiator. Funny part was the front was plugged with mud. The fan side was plugged with oil from the breather. The radiator needed a good rinsing the hit with purple degreaser and soak a bit then rinse it off. It looked nearly new afterward. I yanked the old breather bottle off and install a Mopar1973Man Crankcase vent.

Well... On my way home tonight my exhaust system started to fall apart. I lost the section between the muffler and the U section over the axle. Time to give up on the old stock pipe and replace it completely. I need a 4 inch exhaust system that comes with a flow through muffler and straight pipe. I'm wanting something that is designed to combat road salt and rusting for a long time. Time to see what you all suggest for the exhaust system. At this point, my truck is parked and I'll be using the 96 Dodge Ram 1500 for the time being till I get the new exhaust or manage to make a turn down for my existing system. So I need to get to work tomorrow on @IBMobile VP44…

Totally stock right now, except airdog 100. Will the switch in MPG mode work if I have no idea if my 2001 has ever been programmed on for high idle? If I need "re-flashed" can quadzilla do this or only smarty or anything else. Last resort being the dealer? MPG...mine is two wheel drive. I keep reading about people saying they are getting well over 21 mpg. Best MPG I've ever gotten (since 2005), even using cruise control has been 18 1/2 (long hand, not overhead reading) With switch in MPG mode what's a good "guessimate" people have seen in MPG? Thanks

Was sitting at idle in the parking lot before shutting off the engine. I noticed a squeak under the hood, I know my serpentine belt was squealing a week ago after hitting a big puddle and thought that was the case, so I popped the hood and had a listen and it's not coming from the belt. It's loudest on the driver's side around the valve cover. Is there anything under the valve cover that would make a squeaking noise, injectors, valve springs, could it possibly be the vp44? I don't notice anymore smoke than usual, loss of power, and there's no blow by

Hi, Spotted these 2 connectors, 1 grey, and 1 black coming out of harness near left front side of engine. Black has what appears to be 2 contacts, and grey has 3 contacts. Picture is taken from ground, left side looking up. Thanks. Leaky
