Not yet, but I'm looking into going to Granite State Dyno and Tune when I get it built and having them make a custom tune, and getting their prepackaged one. Just not sure yet.

 

You like a custom one much better than the canned SCT tunes. They can match it up to your truck. Plus, allows you to get all greedy with the horsepower!!LOL

 

Well... I finally decided to tear into the motor and do some stuff I had sitting in boxes. It really was all prompted by a failed IPR valve. At Minuteman Trucks during Wade's dyno day. I was next in line, planning on deafening anyone not already deaf from Dick's truck. No start. Frig...

Probably the best place in the world to have a failure though - a diesel shop with mechanics who were off duty. I forget his name, but big ups to the curly haired dude with the beard for identifying the IPR as the culprit.

Bought a new one, and a new HPOP (got the wrong one though unfortunately). Still had an EGR delete, oil cooler, 6.4 banjo bolts in a box too... So did all those. I get down to underneath the oil cooler, and found that the OE screen had already been replaced (it was obvious at several stages that someone had already been into the motor - still not sure if that's a good or bad thing). The screen was the newer stainless one, and was COVERED in junk. tossed it, popped in the new one. The IPR screen was also intact, no junk in it. I had originally planned on replacing the HPOP proactively, but since the screens were ok and I knew it was good, I left it alone. With the EGR delete, it'll be pretty much as simple as taking the turbo out if I need to do it later.

Anyways, so we get the whole thing back together, and I went to fire it up... And I forgot to put tension back on the belt - snapped it in half. DAMN! We took out the shrapnel (that belt is friggen massive), and cranked it without one, just to see if it fired up. After a minute of building fuel pressure, it fired up with a slight hesitation (took some cranking to build oil pressure too I think). It's pretty obvious that one of the band clamps is loose, because soot is shooting out. It was also very cold and a rough start, but it's running again. There was some oil in the turbo I think too, not sure why. It got turned around a bit for visual inspection - would that do it? I've heard of turbos pissing oil internally if they get flipped upside-down.

Just ordered a new belt. Won't be able to get back up there until the end of the week to re-check the clamps... I may also be missing a gasket there. Is there one from the y pipe to the turbo? If so, it's missing. Same goes for the new up pipe... There wasn't a gasket before, and there isn't one now.

My concern is a stuck injector - there was a LOT of soot on the fire-up. It only ran for a few seconds and we were getting smoked out. Time to do it outside. Does any of this sound familiar to anyone? Am I missing something critical?

Pics coming soon...

 

Wait that was you with the 6.0 Who wouldn't start? I Was parked right next to you out Back and suggested you try unplugging the icp lol

 

Yup... that was me. Your truck has inspired me BTW lol... VERY nice setup.

Ya the valve was toast, all set now. I'm just hoping the extra soot is a cold start related issue and not a f'd up injector... That would blow hard.

 

Thanks! And that's funny, I didn't even think twice about who it could have been.

I Don't think injectors stick open on these, I think they may get stuck closed though.

 

Unfortunately I'm not a Diesel tech, I know gas engines, transmissions... just never gotten deep into a Diesel before. I've had a few rough cold starts - i'm wondering if it could be FICM? Seems suspicious though that it'd start like this right after a rebuild though...

I think it just has a loose band clamp, and it's pissa cold. More to come...

 

Define rough? Definitely could be ficm, or glow plugs. I have a code for 1 bad gp and here's how mine starts at 17. Pretty decent cold start. I'm also running synthetic valvoline 5-40 with rev x which knocks down stiction. You may be experiencing that to


bad ficm

 

Man, that first video you posted made me get a little nostalgic for my old 6.0L...

Then the second video reminded me when the injector module went out, and I was no longer nostalgic. At least that one started. Mine quickly got to the point where it wouldn't fire.

 

Just ordered the BPD FICM - pretty sure that's what it is. The heck with it, I'm just going to throw better aftermarket parts at it everywhere.

 

Craig, I had the turbo on my 6.0 replaced, due to it leaking oil. I had it in the dealer, and they found oil in the tubes between the turbo and intercooler. So, had a new turbo put on. Don't know if this is the case with yours, just thought I'd let you know!

 

That wasn't blowby getting sucked in through the intake? I did the CCV mod also while I had the intake out. I'll clean the intercooler out when it's a bit warmer out - i'm always afraid of dicking with plastic parts in the winter.

This was definitely black sooty diesel smoke, not burning oil smoke. Sounds/looks exactly like videos of a failing FICM. It's been slowly doing that in the extreme cold, even before the IPR valve failed.

 

No, I had just had the intake cleaning done. Ford was using my truck to test out the cleaning system from Wynn's.

 

Might as well get the intercooler pressure checked while it's out. Had that relpaced also, it was leaking!

 

Its been a while. Any updates?
