So

Sorry, the Title was supposed to read "So I bought a 01' Powerstoke Excusion today".

I'll upload pics tomorrow. Got a GREAT DEAL on the rig today and couldn't pass it up. Used car dealer, not private owner. I'm new to diesel engines but performed the "Blow By test", checked for leaks, sounds, etc based on what I found in numerous Youtube posts of mechanics and in forums

Lifted with possibly 6-8" with springs and blocks (4" as well, believe me, they're coming out IMMEDIATELY upon buying a Hi-Lift jack tomorrow).
Quad shocks in rear and Front.

42" Swampers on Weld 16.5 wheels with an additional set of 35 BFG 16.5 rims.

The engine and trans sound and feel amazing. Not sure of the gears, but based on the feel and performance, I'd guess 3.73. I kept it out of O/D. Even though the tires soak up the shift feel, each gear shift feels STRONG.

* Has a pyrometer, Boost and Trans temp pillar (Fully functional. The Pyro at WOT for 1 min only reached 900 Degrees max. The trans temp remained in the 160 degree range. Boost reached 10 PSI max.

I've got a windshield crack which will need to be replaced likewise with the rear window. Lock mechanisms will need to be rebuilt (found a post about the repair, free).

Upon my analysis, I found that the HPOP is leaking out the rear and noticed that the previous owner has a rubber hose about 2" off the hose as if there was a leak. So I'm not sure if the HPOP O-rings need to be replaced (just may for assurance).

Needless to say, all the fluids will be swapped out in the next day or so and will continue to drive my Prius as the daily driver (Yes, I own a Prius).

Sorry for the long winded post, but how do I find out what tune the ECU has if any?

By the way, sold the 98' Ford Expy for this.

A Prius owner and a Mac user ? Probably sipping a Starbucks as well ???

Ok , enough razzing , welcome aboard the org.

The HPOP lines are under enough pressure that I don't believe a piece of rubber hose would stop or slow the leak. Maybe they put it there to stop line rub ? I believe there is a snap ring on the back of the HPOP , maybe it's loose ? I would go ahead and replace the HPOP line orings while your searching , they are cheap ( dieselorings.com ) and they make a mess when they blow. You'll need the release tool for the fittings. I ground a 9/16 box end down to about 1/8" thick and it works.
All leaks up top show in the valley and travel out the rear drain holes working their way down the back of the block by way of the inspection cover / rear main seal , so always start up top for leaks.
Why turn the O/D off ? Does it not pull itself in O/D ?


Sounds like a sweet ride - throw up some pics !! Preferably not of the Prius ....

Hello and welcome to the Org!

Sounds like a pretty nice rig. Looking forward to some pictures.

If the Ex didn't come with some kind of tuner, then most likely it has the stock tune on it. Courtesy of the EPA, most dealers would have to set the truck back to stock.

If you are looking for a good source for the O-rings, check out both Riffraff Diesel and Diesel O Rings.com. Both are good reliable sources that I have used regularly. I've even had the guy at dieselorings.com (Bob, I think) call me at home at 10:00 at night when I ordered something stupid.

Have fun, and enjoy the new truck.

Thanks Gene! I'm excited!

Just to cover the basics, if there is a tune on it (Programmed ECU by an unknown tuner) and I buy a tuner and adjust the ECU, would I be adjusting a modified tune and not the original ECU programming. I may need to buy a tuner just to "poke" around and get the baseline original programming and start from there.

Yes, I found Rifraff's diesel's website before and heard great things about their products. Good to know that others have great experiences with their service.
I found that they sell a "regulated return system" that everyone is raving about. I may order one form them in the near future.

The programmer would overwrite the program stored in the PCM. I've never used a programmer, just the PHP Hydra chip (and I just installed it today). I believe you would have to back up the program in the PCM using the programmer before overwriting it with the tunes in the programmer.

I am running one of the FRx (regulated return system) from Riffraff. I really like it. It smoothed the idle and quieted the engine.
