Injector Swap Question

I think I already know the answer, but just want another "set of eyes" on my plan.

I have a 2014 that I installed a new set of BBI injectors and delivery tubes into ~15k miles ago.

I purchased a 2016 that has factory injectors with 42k miles on.

I'm going to sell the 2014, but before I do I'm planning to swap over the injectors so I retain my lower mile newer injectors.

As long as I keep the delivery tubes paired with the injector they are already with, I should be fine to swap without needing new delivery tubes. Correct?

Thanks

Anyone selling 4th performance parts?

I drive a 2013 and want to get more go fast parts but I figured I might as well ask/see what’s out there for sale on here. I’m open to anything. Thanks in advance

Turbo Time?

152k with full diet. Been throwing codes since October. Only about 5 times but never this many. Probably go with a Cheetah unless convinced otherwise. Taking suggestions to vendors. CPP has this listed as only up to 17my. Is there a difference? Specs look the same on fleece website. Thanks in advance.

68rfe same issue after rebuild

Bought a 16 limiter with a " rebuilt " trans. Few months later it would bang hard into first or stall out and go into nuetral when I came to a stop/go. Truck would bang hard into drive from shifting from park. Had a should tell me it needs to be rebuilt because of the issue. I had no proof of it being rebuilt already so I went with it. Had it rebuilt & same issue. Still hangs harder into first sometimes. Guy said it needed to be relearned. Took it back a week later then he said it was a bad defect valve body. New one in. Then he said solenoid new one in. Then took it back few weeks later same issue then he said it was trans leaking fluid that's why it was banging again. Fixed it then same issue weeks later. Now he's saying it's a bad trans computer?!?!. Over 6200 still having the same issue!. Shifts like crap too since rebuild or shifted the same. I'm thinking on taking him to court for my money back. Any ideas? Any shops you recommend in SWFL?

At a crossroads

Got a semi low mile(145k) 2nd gen 24v that I’ve been daily driving and I have fixed/cleaned up over the last 3 years. It’s got a Carli suspension, 5” straight pipe axle dump and some other small upgrades, but otherwise the engine and transmission are completely stock. I did rebuild the trans just because it did need some work and I figured I would just do it then. Otherwise the truck has been extremely reliable (more reliable than our 2021 rav4 go figure) Now, I am at crossroads. Buying another truck soon so this truck is about to get a full makeover. Repaint, rust removal, gutting the interior, engine and transmission upgrades and some other stuff. Basically I want it showroom quality. But the thing is that I don’t know if I want to keep going down the reliable but a little boring oem+ route or if I want to make this thing into a full off-roader with tube bumpers, beadlocks, complete suspension overhaul, etc. Plus I would be more afraid of putting miles on it and damaging it if I kept the oem look. I wouldn’t really care about miles or damage if I made it a full off-roader. it’s been something I’ve been thinking about for a little while now. This truck means a lot to me since it was the first truck I ever bought so I want to treat it properly. I just don’t know if I want to go that crazy with it. Wondering what y’all think.

Why are early 4th gens so cheap?

I keep seeing 2008-2014 cummins powered rams for less than I've bought 2nd gens for and with less miles. Why are early 4th gens less sought after?

Anybody got an OEM air filter setup they’re willing to part with?

2017 Ram 2500. Bought the truck used and it has an AFE aftermarket cone tube and filter. Wanting to go back to stock and wondering if anyone here has a stock box and tube that they’re willing to let go. I don’t mind buying it and paying shipping. Just tryna see if I can save a few bucks and someone here can clear up some space before I buy a used one off the bay.

Thanks! 🤙🏼

No boost after truck sat

Hey guys, we have an 09 6.7 g56 that sat for 2 years and now has a turbo issue. Zero boost at any point. Is there a way we can unseize the turbo without pulling?

2104 2500 6.7 Cummins Fuel Issue

Hey everybody,

I switched out the fuel filter and fuel water separator on my fass system the other day and since then the fuel pump will not run. this happened last time I swapped the filters and I had been checking the fuses when I misplaced the fuel pump fuse. A day later when I realized this and swapped it back the filter started humming and it fired right up. Obviously not the issue this time, I have checked everything I can think of, if anyone has any ideas please lay them on me.

Exhaust brake sound nightmare

2014 3500. I had a bad exhaust manifold leak last year that got worse and worse. It would make a reed valve sound when my exhaust brake would engage and eventually would make it when turbo spooled up. Ended up replacing the stock manifold with a 2 piece BD unit and while they were there I did the banks heater grid and intake horn. Noise went away for 10k miles or so.

I took it on a 2000 mile trip towing my camper and it started making the sound again on exhaust brake and while pulling hills spooling turbo. Also wasn’t getting full boost. Took it in again and replaced every stock elbow with mishimoto silicone boots as well as added an exhaust mount just past downpipe that was not there. They also checked all of the work they had done on manifold and said it was fine.

Anyways I get the truck back and have to use it immediately to haul again and it is still making the sound while engaging the exhaust brake. But if i gas it and then engage it again it sounds normal. I am getting full boost but the sound is annoying.

What else can I look at? I was going to check the egr delete plates and see if there is signs of leaking there. Anything else to check that’s easy?

I do trust the shop and I really don’t think manifold is leaking again.

A reminder as to why I have the opinion you shouldn’t use a cheap oil-bath air filter on your Cummins (or any) truck.

From left to right is a new piston ring, low mileage, higher mileage (289k miles) with regular maintenance, then one that ran a K&N from 104k to 179k miles, when is started knocking. It’s rough edge is sharp enough to cut you easily.
