oil leak P0603 and p1211 codes

Coming through town friday (steep long hill) and the truck lost power substantially. Check engine light. Otherwise truck ran smooth. I could hear the turbo a lot more than usual.
I threw codes P0603 Internal control module KAM error
and P1211 ICP pressure above/below desired

I believe the ICM code is from from my chip????

Now I see oil in the valley of the motor but can not come to any conclusion where in the valley it is coming from. Any ideas where I should start?

I am sooo lost. I tried searching but nothing seems to realy pertain to my circumstances and to boot, I "NEED" my truck next weekend.
any help would be greatly appreciated guys!

Do you have a monitoring device? Sounds like you lost oil pressure. I would guess you're a STC victim... based on what you're describing.

Nevermind... Just noticed you have 7.3 liter. Having said that, P0603 usually means that the PCM recognized a tune of some sort and usually doesn't lead to loss of power.

I'm with taskforce in that you have a HUEI oil leak. The codes are probably responses to TW Chip. Tunes ask more of the ICP then stock and often set codes. No worries. Clean the valley and have someone start the truck while you are watching the top of the motor. Wear safety glasses as oil from the HPOP can be above 1000psi and if the stream is fine enough it will injure you. Also be aware that the engine fan is now rotating. Keep fingers away! Most of the time oil in the valley is coming from the turbo pedestal o-rings and/or the EBPV actuator. Your situation seems more like a blowout on the HPOP feed lines to the heads (or the o-rings at ether end), o-ring blowout on one of the unused ports on the head, or the seal at the ICP on the HPOP.

Thanks big fuel. I will check again and see what I can figure out. Hopefully not too much of a pain to find it!

I did check after cleaning the valley. Watched as close as I could using a 500W light and a flashlight, lol. could not find anything. I feel like an idot but cant find anything.

what would be my most likely possibilites for an oil leak in the valley?

I know the O rings on the pedistal.
Is there any trouble spots on the pump?

Not that I can think of. ICP uses an o-ring that would cause poor performance and a leak. The EBPV actuator rod has a simple wiper seal and is really prone to leaking. Is the problem still happening?

Well. I took the truck to the shop and the leak was fixed. I believe he said it was the IPR O ring?? I thought if thoes rings were gone you would just have fuel pressure problems not a leak??? anyway. Now the truck is still lacking in power the guys says and the truck stalls now. WTF, didnt do this before. While monitoring fuel pressure and cranking over, pressure would fluctuate between 1800 and 2300, but still not catch all the time. Sometimes it will start fine, others it wont do anything.
New IPR installed, still above noted issues!
I am totally lost. the only possible conclusion we could come to is FICM is screwing up.
any thoughts?
