Buddy of mine has a pair in a boat with 2300hrs. He had injector issues on one, but thats been about it. They run stout.

What model 3126 is it? I have one in a 2002 GMC Topkick that was only made 1 year before they went to the C7. My opinion it's a gutless POS and when it dies will get a twin turbo 5.9 Cummins shoved in it. I believe mine is a 3126D or E. I wanted the hp bumped from the 210 to 300 and CAT refused to do it the way it was unless I spent $15k to do all the upgrades.
Cat's idea of an overhaul on the 3100 is a new block, if that puts into perspective how many have broken rings.

Cummins is the same on any non sleeved block. Your not getting a warranty if they don’t know the condition of your cylinders. Has been cheaper to get a recon vs overhaul on even the ISX lately.
That’s the same for all the brands, they will not upgrade HP if the internals don’t match. Customer tried to get a POS Volvo engine uprated and dealer wouldn’t do it because he only had a 14 series transmission and they claimed he needed a 16 series for the torque which everyone knows is BS.
This is why you never go to dealers for HP. No different than taking your Ford/Dodge/Chevy cab and chassis to the dealer to get the same Hp as the pickups, not going to happen.
The 3126 is by no means an amazing engine but it’s the same as a 5.9/6.7 cummins just HUEI.
I've been curious what one will do with 514 style injectors and a 464 from a C9.
The 3126 with coffee can pump and square top injectors are more durable from a fuel system stand point. Throw a solenoid on the pump from time to time.
The C7 engines pumps are trash. They litter the oil rail that supplied the injectors with metal. Cat has a filter kit available now.
I can provide you with the iron splits if it helps you.
The engine family pretty much splits at 230hp. The same engine hp can have aluminum or steel pistons, two different Turbos, different balancer.

man I appreciate the input but I have no idea wtf yer talking about...I know little about these...the round top pump is better? they have that rubber fuel line to the pump that contaminates everything?
iron splits? guessing that's the specs on it...lol..idk man:umno:
We haven't caught any losing metal, usually leaking solenoids or the cooling jet on the rocker arm is stopped so the solenoid on the injector isn't being cooled any more and they die. We barely see them now though, so they could all have major pump failures late in life and no-one would bring them to us. I have four in my territory that I'm aware of.Done several pump swaps and injector replacements on the common rail C7S. With a tune they are bad mf’ers but that fuel system is trash. Almost like the Bosch system on the DD13/15 that comes apart and puts metal in everything including the fuel tanks.
Change the oil, install a pyro and rock out.
Be cheaper to put compounds on the Dodge!
