Not if you have the Cali PCM.
On the other hand if you get custom tunes for the Cali injectors you will gain a little more than a truck with stock AA (90cc single shot) would. The cali injectors are closer to the potential of the 140cc injectors in the SD (99+) 7.3. Plus since they are split shots they will run a little smoother. They do, on the other hand take a bit more HP oil than the AA's but the cali trucks seem to do pretty well.

Just run the cali pcm. Like Jim said above, wiring is a little different I think. Finding a cali pcm isn't that easy iirc. If it were mine, I'd stay away from the cali version, jmo.

Should be about the same as regular AA code injectors. The only issue is that there aren't a lot of them out there. I think they're AB code injectors. Someone correct me if I am wrong. (I know they're AB or AC code, and I think the AC's are the E99 injectors) Jim Rose would know for sure. Send him an email.

The AB codes can be used in your truck if you get a chip burned for the ABs. Your stock HPOP probably won't be able to keep up though since split shots use quite a bit more oil.
Personally I'd sell the ABs and either use stock single shots or get some upgraded single shots. Split shots are a PITA..

AB codes were 120cc split shots found in OBS cali trucks and Early '99 SDs. Late 99 went to the AD 140cc split shots. AC codes are 160cc single shots with the same nozzles as our stock injectors, so basically they are a factory built stage 1 injector. The AC code injectors were in the T444E in dump truck and school bus applications IIRC.

hang on, besides that you should be good. I agree with the above, if you can swing it cost wise, don't sell anything until you get it figured out. Any idea of what happened to the rings?

Glenn, I was told these trucks are notorious for breaking rings in the two back cylinders. I had one mechanic say due to the cooling system has to pass through front to rear and by the time it gets back there its not really cooling so it puts stress on that cylinder. I talked to another mechanic that said because of the injectors either spraying too much fuel or not enough fuel.... I'm not sure really. Honestly your guess is probably better than mine. I bought this truck from a family member a couple years ago and it had set for nearly 4 years without anyone driving it. When I got it home the fuel bowl was gelled the air filter was one big dirt dobbers nest and the oil was low. I changed and cleaned all that then took it to Ford because it smoked really bad. They replaced 4 injectors and then the smoking got worst. With help here I narrowed the smoke to the number 8 cylinder. Pulled the head and really didnt like what I saw...

I actually found an engine with 150k on it as cheap as I can rebuild it and the used has a warranty... If I build it no warranty... I am pretty confident my engine can be built but i lack the knowledge and time.. but more knowledge than time....... What is the ghost?

I would bet that the piston cooling nozzle for the #8 cylinder got loose or completely came out and wasn't spraying oil up to the piston before saying that the coolant caused any issues..

Travis, you may be correct. This is my first diesel so my knowledge is very limited I can only say what I have been told by other people... Everyone has some type of justification but with my little knowledge I can't call BS on them.

I hear you. We've all been there. When you pull the engine out to swap, pull the oil pan off the bad engine and you will see the piston cooling jets at the bottom of the cylinders, aimed up at the pistons. Those jets spray oil up to the pistons to keep them cool and lubed. If the hold down bolt for one of those jets backs out and the jet comes off, it's all over for that piston. Look and see if the one for the number 8 piston is missing or loose on your engine. That's why a lot of people will weld the jets in place when they build these engines. It's not a common problem, but it CAN happen.
