2nd Generation Dodge 24 Valve Powertrain

On my recent trip ran into problems that caused me to turn around and head home Very low power and limped it from Indianapolis to missouri got within 40 miles and died out no restart. Found lift pump hardly pushing any fuel. Got towed to house and investigated. Found in tank fuel pump screen plugged Cleaned and retested- still poor Put another in tank pump and filter. don't have $ for better system at this time My pressure gauge won't read cheap hf kit But definate improvement in flow and pressure No lite on dash But scanner came up with p1689. P0216 and p0382 Did the W-T ground mod and the p1689 went away Still have …

Hello everyone, a while back I installed a bd boost fooler along with a set of RV275 injectors. I installed a boost gauge before this just to see the difference, if any before and after this was done. My truck would build 24ish pounds on a hard pull, same with a trailer behind it. No change in boost after injectors or fooler. I had my scanner hooked up yesterday playing around and noticed my ECM was seeing 14lbs at idle, and when my truck was actually making 20lbs the ECM would show 34lbs. Shouldn't that be setting an overboost code? Was just curious if this was normal with the foolers?

@Dynamic This one is seeking your advice. I can't afford one of your valve bodies or a converter right now so its time for a shift kit. Transmission was rebuilt to factory specs by Cottman Transmission about 25,000 miles ago, before i bought it. Works fine, no slipping or other issues. I use it for a daily driver with occasional hauling/towing, max load of 10,000lbs. I have installed Sonnax accumulator piston, second gear super servo, billet band strut and anchor, Rostra transducer & OD/TC solenoids, Borg Warner pressure solenoid, LPW deep pan, and adjusted bands and TV cable. I do not like how these transmissions shift. To me they shift too soft. I like a trans that …

Seems to be sensor or computer related. Had a 10k machine on leaving a stop light she shudders my eyes go wide and I pull the shifter to first no change. At this point I think it's just slipping with a very light foot I get the load moving with minimal slipping. Ounce going I get 1upshift then lock and I stand on her roaling coal. Hunkered down and accelerating with no slipping. It didnt hit me yet I was starting in second. Get where I'm going check fluid its good shut truck off . Go to lunch later no trailer truck sluggish to move then I realized it's in 2nd. Just for kicks I shut it off rolling to stop light turns green issues gone. Ever si…

Please mention sensors, anything you know to check for. A complete list of things to check is what I'm after...... thank you.

I just got done changing the oil in my truck. This is the first time I changed the oil myself. I used Goofy-Lube the last 2 times (I know, I know, WHY would you do that...). When I went to take the drain plug out I noticed 2 issues, one, the square spot where you put you're 3/8th inch socket wrench was partially stripped (Goofy-Lube) and two, the plug was so tight I had to get a cheater bar to break it loose (I won't be going to Goofy-Lube anymore). My question is if anyone uses any of the drain valves in place of the drain plug. I saw some for sale on Geno's Garage like this one and this one. Just not sure how safe it is having something li…

hey all...I had a stuck injector last weekend so I replaced them with some even bigger ones (220hp vs 175) bc they were the only ones I could find on the saturday of memorial day weekend. Is it obvious with how the truck idles if there's an issue with the connector tubes? I dont know if there is, but the truck idles meaner with the new injectors anyways so a comparison to before isnt fair. The truck appears to be running fine, but it is way smokier than before. I know that could be the injectors just being bigger and smokier. We couldnt find any connector tubes over the holiday weekend so we reused the old ones that have been tightened on multiple times, and clearly over…

So this morning I started the truck and drove to class and everything was normal. Get out of class 2hrs later and go to start the truck and as soon as I do I know something isn’t right. Truck had a miss and. Is smoking white haze pretty bad. Whole engine is shaking and engine is missing sounds like. No knocking or anything like that. Injectors are only a year old. What would cause it to just go bad while sitting for a couple hours? Had the truck towed to my apt and am going to swap in my stock injectors once I get time (currently pouring cold rain) and hopefully that fixes the issue

01 Cummins with 300k, I got a p1762 and a p1763 code. Replaced all solenoids internal on the transmission.(haven't touch the internal wiring yet) Ground is good, ran a jumper wire and by passed the pcm, made no change, 5volt line on data says it's stuck at 4.98 but doesn't show any v coming out of the pcm to the transmission, all grounds check out with a it break out box. Pickup is stuck in 3rd year with 108 gov press psi at idle and gov pr duty cyc is at 1, when you press the od switch, it's saying pressed but it turns right back off on snap on scanner. I can see life data and I have ran all relay test I am think of. Pcm has 12v coming in, ECM does also. Batteries…

I have read the Caterpillar, University of (Indiana?) and Air Dog, etc. documents about entrained air in diesel fuel affecting power and retarding injection events. Does anyone know if that significantly affects MPG and EGT in our trucks, specifically? It sure seems like my EGT is higher than most (700-800F), my MPG is around 17.5-18 (hand calc) even at 65 MPH in average weather/wind conditions running empty. When I give the fuel a super dose of PDS gray stuff to increase cetane in an effort to advance the ignition, everything improves - but PDS gray isn't free, even if it isn't expensive. I ran Rotella T6 almost 10k miles and had an oil analysis done to check for fu…

Hey guys, Im set to move across the country in 2 days and I have been finishing up work on my 01. I took it for a shake down drive last night and everything was going well until (fortunately) right when I got back near my house. It starts to surge and stutter and wants to and does shut down. I took it for a short drive the other day and I had the same issue. I chalked it up the Hot Rod VP that WAS in it, because it was giving me a really hard time loping at idle and low load. I went ahead and switched out the VP for a DAP SO unit, since I had wanted to switch back to an SO anyway. I finished that up along with a new cam sensor, and she started and run beautifully. So…

I have been tossing and turning, surfing every post I can find that seemed related for 2 weeks trying to get answers. I am on the verge of rebuilding my 1998.5 as soon as I buy a newer rig to daily from now on and have this one as a toy. I’ve read more than one post about 6.7 crank in a 12v. And ppump on a 6.7. I was looking at stock bore or maybe 20 over(is anything bigger safe?) with a 6.7l crank and it seems I need shaved pistons to make stock compression. Are the crank gears interchangeable? When I rebuild it I’m going to try my hardest to get the crank polished and balanced, pistons coated, rods polished and hardened. And maybe my head milled off if the budget will a…

Hello everyone, I need some help determining what is happening here. I’m supposed to be taking my truck to WY in November, but this is a problem. My truck has been running ok but it doesn’t get a lot of use these days. Over the summer, I barely started it so it had fuel in it from spring time. I tend to run 1oz/1gal of 2 cycle oil in the fuel. It is stock other than putting a different lift pump and fuel lines for the pump. It has started and ran ok cold. I’ve fooled with this just a bit over the last couple weekends. I got in it and have lots of bluish/white smoke, but only after past it being cold. Today I started it and it was runnin…

Ok Long story short, is still very long: I had my NV4500 transmission go down a few weeks back, in Casper WY. took is to Thomas Crawford auto repair. I had a very good experience . But now I've got issues. History: Took about week to get one sent to the shop in Wy, from Midwest transmission in zumbrota MN which isn't far from where I live. The repair shop and I decided to upgrade to the 1 3/8th input shaft,plus all the other updates that Midwest Transmission and gear, does to these trans when rebuilding them. For the clutch, I opted for the SBDD and new hydrolics. Hoped this would work better with my towing needs. Finally , The installer p…

I have read the FSM for changing out the center bearing on my 2-piece driveshaft, and looked in the Parts List in the Articles section (which is for 2001/2002). Part # listed is: 04773014. When I go to Rock Auto that part number isn't listed for 2001 models, just 2002 models. For both years, they list options with two different diameters (even when I've selected Diesel and Auto, etc.) 1.5748" and 1.3780". Is there a good way to determine which I need without removing the clamp for the rubber boot and putting calipers on the shaft? EDIT: The difference is in the Wheelbase. If you have a 138" wheelbase (Quadcab, shortbed), you get the 1.3780" bearing. If…

Hello. Just got a package from Vulcan Performance. 1/2" big lige kit for my 98.5 24v. I got the 90 degree fittings in both ends, vp44 end has tapped port for fuel pressure sensor. That thread shoud be 1/8 npt right?? Was wondering what that one fitting is in the picture, the one with plastic cap on! It says 1/8 bsp in the cap. I was remembering that those two have different angle in threads. So can I put a needle valve directly to that 90 degree fitting closest to vp44?? I have also 18" long grease gun hose to get the sender away from vp. Can you give me some ideas to assemble the kit? Thanks and greetings from Finland!

I am ordering a rental Smarty and high idle switch from DAP later today. Sole purpose is to enable factory high idle. It's my understanding that all i need to do is install any Smarty tune then return the truck to stock tune and I'm good to go. Is this correct?

Thanks to this forum, I have heard about the thee cylinder high for very cold days. However, I have never experienced this occurrence until last week during an overnight low of 20 degrees at my property near Baker City, OR. I fired up the truck, turned on the exhaust brake, and went inside. A couple of minutes later I heard the engine slowly increase in RPM. Then all of a sudden it started making such a wild clatter that I thought I was going to have to shoot it and put it out of its misery. After thinking about this for a couple of minutes, I realized that this must be the three cylinder high idle feature. I touched the throttle and the engine went back to a norma…

This truck isn’t my daily so it sits days at a time. I inherited a 99 Cummins with issues and have been working through them. Random no start, replaced cps, problem fixed. Random loss of tach and acceleration, replace apps, problem solved. Then one day I’m driving and the trans goes into limp mode, I don’t have time to deal with it so I park it for a couple weeks. When I go to pull it in i can manually put it in first but if I just use drive it’s still in limp mode. The alternator is also not charging now. For whatever reason neither of my scan tools (mx808, Verdict) can communicate with the transmission. However I can see the ECM and I have code p1693. I check power and …

Hello everyone, been quite a while since I have been on the site. Mostly just life dictating where my time is to be spent. With that said though, I have come to ask for the wisdom you guys have and get a little guidance on what I hope and believe to be a small issue. I literally drive my 99 a couple times a month at best, maybe 5-6 times startup and move somethings around on the property. So maybe a month ago I started it up to move a trailer and immediately Knew I had a busted brake line. No big deal, ordered a new set, waited to have time to do it and repaired them. Fast forward to Tuesday and I decided to get it out for a little drive to really ch…
