I bought a brand new crane truck, it's a Pete 365 with an isx 12. I'm just wondering what I need to know about this engine, Like what are common problems with it.

you need to start here. Check the mfg date of the ECM itself, not just the engine. ntsb recall here ...

looks like my ECM is part of the recall, I'll call the dealer monday morning. I read through the fuel pump recall information and I don't see anything about the ISX12 being involved in that,looks like that one is an ISX15 problem.
Can the mandate on my ISX12 be removed just like on the ISX15 ? I would like to keep it stock until the warranty runs out and then possibly remove the mandate.

If you're going to "keep it stock" for the duration of the warranty, as soon as the truck comes back from Peterbilt getting the ECM issue corrected, INSTALL A BYPASS OIL FILTER on that thing IMEDIATELY!
Cranes by the very nature of their job, idle a lot. The EGR percentage is very high during idle, so increased filtration to tackle the soot issue is your biggest concern. I'm sure your well aware of this, but don't do oil changes by miles on a crane truck, but by hours. Knowing that you will be idling, and naturally heavy soot loading the oil, I'd recommend 200hr intervals. Oil is cheaper than motors.
Make sure you keep on top of EGR system tune-up/soot clean outs as well because of the stated concerns.
I don't know what 400k miles would be in hours, but beware the XPI fuel pump self destruct issue and change it at or before this time.

So your saying this engine has the fuel pump with the ceramic plungers? I thought they would have changed that setup by now.WTF?

I've been reading the bypass oil filter thread so I can install one on this engine. I notice the oil cooler is a different design on the ISX12. Which port would be ok to use? they are all right below the turbo. Also it looks like the easiest place to run the return line to is the plug in the side of the oil pan, is there any reason why that's not a good place ?I tried to post a pic of the cooler but I can't get it to work.

Ceramic plungers were worse than the newer steel. Even if it is updated and has steel plungers, it slows the problem down, but they still fail at about the 400 - 500k mark and take the engine with them. It is simply a bad design of the pump.
