Those figures are helpful, thanks!





Here a couple of screens from mine. There are 5-6 screens that I scroll through but these two I use the most. One is for hard/no starts and one is for general monitoring.

Torque has a plug in for RealTime Charts. I haven't done much with with other than running the default charts, but it looks cool while in use. I'm not sure how useful it is outside of monitoring O2 values and some other things. I'm sure there are customs reports/charts out there others have created.

 

I'll check my spreadsheet. I have links to things that might help. The PC/ED manual has values documented - if you can get your hands on one for your model year.

In the meantime - hit visurveyor and knotreel w/ some reputation points for posting their values!

 

Done! Thanks for pointing that out. I had to look up and confirm what that was.

 

db. I do like the last name. I think I know somebody with the same.
Good luck.

 

Well...... now we have a crank no start. Drove the truck over to my buddy's house to hook up his scanner. We had it hooked to the scanner engine running, and then it just died and would not restart. I have base oil pressure ICP reading 0psi and IPR 85% did a Air test with a mechanical pressure gauge hooked up you could hear air coming from the intake side and out of the oil fill cap. As soon as you shut the air valve off pressure would bleed down immediately. And we used the scanner to close the IPR. The guy I had helping me seems to think with what happened it could be the STC fitting blew apart since it was an abrupt engine shut off. He suggested maybe pulling the IPR valve first to look and see if the screen is blown out, he said maybe he could be closing the valve but if the screen is blown out it would matter.... thoughts?

 

IPR could have a piece of screen in the valve, you may see the split or a piece missing when you remove the valve
you can clamp a air hose to the end of the IPR and bench test it -- should close off when you apply 12 volts
would be a good time to do an air test thru the IPR port if your Buddy has the fitting

 

Well that's progress, actually. Now you can trouble shoot it.. You are saying that the ICP is 0 while cranking? while the IPR is 85%. Like you said something blew, not just leaking.

 

Yeah when cranking the ICP was reading 0psi and IPR was 85% you thinking the STC fitting is a good possibility?

 

Or something worse?

 

90% of the HPO leaks on the 05s and up are from the STC fittings and standpipes/dummy plugs (according to Diesel Tech Ron). However, I just went through this and had a plastic piece of the screen broken off and was wedged in the IPR valve. 0-15 psi when cranking at 85%. Since your losing pressure immediately and not over a short amount of time I would be sure to look at your STC.

 

SNugent09 -

dbb1porter's and HydroTek's advice is good IMO. Next step for me would be to pull the IPR valve, as they recommended.

With the IPR valve out, if all looks good with it, then do an air test with the fitting that threads into the IPR valve port. You can get them from various places, but read the reviews carefully. Some are not made to very tight tolerances and you can end up with one that doesn't fit well. I am out of touch on which ones to buy - sorry. The best thing about checking through the IPR valve port is that you take a leaky/bad IPR valve out of the testing process. If you don't hear any leaks with the IPR valve out, then the problem is likely to be the IPR valve itself (process of elimination)

Also - probably the best thing to do is to "at least" pull the drivers side valve cover before doing the air test. Pulling both valve covers may be necessary, but nothing wrong with pulling the drivers side and hoping that the passenger side is ok. If you don't want to pull the valve covers right away, then it is best to listen for leaks with a hose (or automotive stethoscope) that is placed down into the oil fill tube and then into the ccv opening on the driver's side valve cover. Pull the valve cover that shows the most leakage. If heavy air flow is heard in both places, then you are "probably" looking at the STC fitting.

Be careful and don't drop anything with the valve covers off!

If you find that you have the original style dummy plugs and standpipes, then I would recommend replacing them on BOTH oil rails. The original 05-07 standpipes and dummy plugs were removed w/ a 10mm hex drive. The upgraded standpipes and dummy plugs require a 12mm hex drive.

I'll post a few links on doing the air test and testing the IPR valve. One of my links is to a video that has some errors in it (HydroTek pointed it out thankfully). The main thing from that link is to show how to hook up the air hose and power the actuator. The problem is that his explanation is a little off and the way he connects power to the actuator probably ended up frying the actuator electronics. I'll try to "cull" that one from the future posts.

Bench Test IPR (best to get a spare IPR pigtail to use - part # 6E7Z-12A690-DA):

IPR air test tool (lots of places sell one):

Air testing:


Leakage noise from the oil fill tube on passenger side valve cover or the ccv opening on the driver's side manifold (or the turbo drain tube opening) can give you a good clue where a leak might be. Leakage sound at both places would mean STC fitting or IPR valve - usually.


If you want to test at the ICP, then you MUST close the IPR valve. I can post several ways to do that if you need me to.

 

Alright, so I am working today, so I was not there. But the fella's house that my truck was stuck at, he took the liberty to pull the IPR valve. He said that the screen had a small piece break from it and the valve was stuck open, he cleaned the IPR and replace the screen and the truck fired up. He did not test drive it and he didnt bring his scanner home from work but he said at idle my ICP psi was between 500-600 and the IPR at 22%

 

Good deal!

 

The reason the screen breaks is from junk plugging it up -- the HPOP has more pressure than the screen can withstand -- so, it splits and all the trapped junk goes into the IPR
The IPR is the "dump valve" for the HPOP system -- the pump produces more oil than the injectors can use, so the excess is dumped

Where does the junk come from? Well it can come from the pump or from a dirty oil cooler install -- a oil filter that is failing or has junk inside it from storage -- or a damaged oil filter bypass(little plunger on top of the standpipe)
The oil that supplies the HPOP is straight from the engine filter -- there is the oval screen under the oil cooler that protects the HPOP inlet -- this one can hold quite a bit of junk, and finally split -- then pass all that junk onto the IPR

 

After replacing the IPR screen. The truck cranks for an unusual amount of time before it turns over. I. Curious if this could be normal after an IPR valve being removed? Once running it seems that the truck runs much better and my ICP pressure and IPR % is much better. My numbers are as follows

WOT/3483 rpm: Baro psi 14.5 VGT 30.3% MAP psi 33 EBP psi 32 ICP voltage 4.5 ICP psi 3922 IPR 77%

I did notice that the ICP voltage is much higher then the previous WOT before IPR screen replaced which was 1.5

I have heard that long cranks can also be a sign of a HP oil leak, so I'm wondering if my initial problem could still be there and the IPR screen just happened to blow out while trying to diagnose?
