Stumped with high pressure oil leak.

So we did in cab studs and egr cooler on this 05 6.0. Also did hpop fitting and o rings. Put it back together now it starts, runs fine, but dies once its warmed up and won't restart. ICP drops to below 400 when it dies, doesn't go over 150 when trying to restart warm. Once it cools it starts up fine. Right now we have the hpop removed and we put an stc fitting with an air hose on the branch tube(to eliminate hpop from equation). Air comes out of both sides of the engine. We changed injector o rings where the nipple goes into, o rings behind the nipples in the oil rail. No change. We swapped out the oil rails and stand pipes from another truck that was running fine and no luck. What are the chances of the branch tube leaking from both sides of the engine? What else could it be?

i dont think yoru test procedure is correct, the air injection is similar but blocking the icp valve or something allows the system to pressurize, usually the leak is heard around the oil filter housing.

He's doing it right. By removing the pump and checking directly through the branch tubes, that eliminates the possibility of it being the pump or IPR valve. If he leaves the pump on, energizes the IPR valve with the oil filter cap off and he hears air through the housing, then the pump is junk.

When you swapped stand pipes did you put new orings on them for your testing?
Have you isolated where the air is comeing from exactly and how did you do it?

have seen in some instances where the injectors wouldn't park closed. could be mistaken for leaks at both heads.

the richest ones are not those who have the most, but those who need the least

No I did not replace the orings. I tried using a stethoscope to pin point the air leak, with the top of two injectors one on each side being the source.

This is what I'm thinking. I have some spare injectors laying around, I will swap them out and see if it helps. I'll have results on Monday.

no,i didn't mean they needed to be swapped. it wouldn't be the cause of your problem. just saying it could be mistakenly sounding like a leak. if that were the case, it wouldn't be a leak causing the problem
