You could change the guage easy enough ,,,If you find you have an HP oil pressure issue,, the guage will isolate which side to look at ,,the scan will give the over all picture

 

If I only use the guage setup what rpm and pressure am I looking for. I know at idle around 400psi or so and up to 3000psi at WOT. Is that correct? Would I see a major difference from one head to the other?

 

Wait a minute I have the HPX on there it helped the issue when I inatalled it but I will have to remove it to test pressures at each head.

 

Yes ,,,to do the heads & the pump individually ,,you need to remove it ...

on the heads ,you will most likely see one side higher pressure ...

 

Man I wish you were correct but I believe it was Kawa (Rog) that got that smokin deal

 

WHOOPS! I screwed that up!

 

What about geting one of those AeroForce Scan Gauges. Their website says it does injector buzz and cylinder contribution tests as well as ICP and IPR data. And it is about $300. I think that would fill the extra hole in my guagepod nicely.

 

I have one and love it! If you are looking for a scan tool with data that is the way I would go. Also if you have a laptop AutoEnginuity is very nice as well.

 

What data can that scan gauge actually read on an OBS PSD?

 

RPM
MPH
ICP
IPR%
BOOST
EBP
OIL TEMP
TRANS TEMP
GEAR
INJECTOR PULSE WIDTH

Probably a few others as well. It will also pull codes,1/4 mile, 0-60mph, and optional are the buzz and contribution test. Also if you want to add other items (temp/pressures) you can buy the need hardware and add two more items. I bought mine from Joey at Terminator Engineering (think big oil!) He has a custom Terminator Engineering face plate on them

 

I found someone to scan the truck. Hopefully this afternoon. I'll relay the findings later this afternoon or this weekend. Lets hope this gives an idea whats going on. Thanks to all, Justin

 

I got it scanned and here are the results:

Buzz Test: all 8 Buzzzin'
IPR: at 35% while driving 1/2 throttle accelerating 2500+/- psi
Cylinder Contribution Test: all good except #5 showed up problemmatic

So I assume a compression test on #5 is in order.

 

With motor hot ,,did you look at IPR DC% at idle ?...

You said it acts up after driving ,& during restart ...

 

I didn't get the spec at idle. The guy that did it for me is a diesel tech at a shop in town. He told me that everything was well within spec. His feeling was that it was an injector given the way the truck runs, but he also added that the #5 cylinder could be dusted or washed down due to a stuck injector. So I am thinking that I will do a compression test, then Injectors if the test shows everything is good in the #5 cylinder. Thanks guys for all the input.
