As most know I do quite a bit of work on the 6.0's here in my shop. A few years ago I sold my trusted 06 and bought a 2017, love that truck and the worry free driving experience I have with it. I do miss my 06 though for sure. Anyway, last year I had an early build 03 come to me in pieces, all has been well, customer was satisfied etc. Well yesterday it came back with a no start condition, so here we go again. Its got a few codes in it, P0341 (Cam Position Sensor Ckt Performance) and P2291 (ICP Pressure Low - Engine Cranking)...so the trucks only making 350-380 psi oil pressure, so looks like Im, starting there, gonna check the cam sensor wiring as well. With any luck its a bad ICP sensor/screen, or a leak in the system somewhere under the valve cover. I guess if the HPOP was bad that's not a huge deal either, just a PIA but the part would be covered under warranty for the customer.

Any who, just wanted to say hi and Im still at it, the 6.7 forum is pretty boring, mostly people just looking to spend money on upgrades and mods. Hopefully this truck doesn't get me too frustrated.

Some news on this head ache...

Air tested the HPO system and it has a leak, sounded like it was pretty pronounced on the drivers side so I removed the valve cover and couldn't really pin point it. I pulled the high pressure hose from the oil rail and the stand pipe, pressurized the oil rail and no leaks on the rail. Removed the stand pipe and made sure that and the braided hose tested good, all was good. So at this point Im assuming a pump issue or the branch tube on the drivers side is broken, which Im hoping its not. I need to get the intake and stuff off, remove the pump and test the branch tube at some point. FYI the IPR screen was clean and damage free, the was a little oil in the ICP connector so Ill address that after I figure out the oil leak.

For those of you that are truly experts, what are the odds that I actually have a pump failure as opposed to the branch tube being bad, Ill find out eventually but Im just trying to prepare myself, and the customer who wont be happy. I will say that I broke my golden rule with this truck as it had many many hands in it when it came to me. I should've refused the job when the second tow truck pulled up with all the parts that were in boxes, but I like a challenge and another one of my customers referred them.

Anything you may think I missed Im open to any help I can get at this point.

As a side note I didn't hear much air leaking from the passenger side via the oil fill tube and I don't see any cracks or oil leaks from the rear cover, I can see the top of the motor pretty good since the EGR cooler is gone.

Thanks,

I think you have a very high probability that the pump is bad. I quit using OEM pumps and now only use the Adreneline. I had several OEMS fail early, and a few that never made it out the door.

 

Agreed and same here, if I have to do a HPOP job on an 03-04 truck, I insist on the Adrenaline pump otherwise it'll be back.

 

Thanks fellas,

I think so too as it builds up to 385psi, however I need to be sure and either way the pump needs to come out. Its just a little baffling that I can hear the leak down low, but I suppose that doesn't really mean anything. Ill know for sure when I open it back up. This is an early 03 so it has the cross over on the intake so I cant even short cut it, plus its a tow truck with an external electric over hydraulic pump on the front. I did try to sell the customer an Adrenaline but he said nope. This is the first 03-04 I used an OE pump in. I guess lesson learned, stick with what I know and sell what works.

Unless the o-ring on the bottom of the pump is hurt.

 

O-rings were all good, air tested with no issues, looks like a failing pump. Parts on order. Ill keep everyone up to date when the trucks back together and running.

Use factory o-rings with the adrenaline pump. The o-rings they supplied, at least when I did mine, wasn't correct and leaked. You could tell when you installed the cover that it just didn't require as much force as it should have to seat and it failed within a couple hundred miles. I contacted Adrenaline about it, not to get anything out of them just as an FYI but they denied it. I put a factory o-ring on and the force to install was obviously different, and I haven't had any problems.

 

In the future you might try using this plug at the branch tube (under the pump) if you think there's an issue on one of the oil rail banks, branch tubes, etc.............I typically hook up shop air directly to the fuel/oil rails, use the following plug to isolate issues at the injectors, oil rails, etc....................it's avail from a number of sources including McMaster-Carr...........they say it holds 100 psi or so, but I've put 150 psi and then some in the HPOP distribution system with no problems....................................also, when testing air leaks hold a short section of tubing up to your ear then place the other end near the source of the leaks --- it will amplify and direct the source of the air leak to your ear --- allowing you to easily "geo-locate" leaks.....................I have expensive noise detection kits (e.g. Chassis Ear), but this "tube" approach is fool proof for locating high pressure leaks.

I was able to air test the branch tubes, both heads were good, installed a new pump primed the system, all is well with the truck once again....lest see how long this pump lasts.

Adrenaline pump this time?

 

Nope couldn't talk him into spending the money yet again....I'm just hoping he looses my number or sells the truck like he said he's going to.
