Smoke I think one issue, shop thinks others

[theswoleguy]

OK First the truck
2004 F250 6.0 (obviously right) Manufacture date 07/03
178K Miles

Just got out of the shop with the following items replaced, updated or deleted

ARP headstuds
Black Onyx Headgaskets
Heads Decked
EGR System Removed/Deleted - replaced up pipe as well
Innovative Extreme Race
HPOP Replaced (for good measure he was right there with the high mileage, but he did say the OE one looked in good shape)
ICP and harness

The truck ran fine for a few days, but occasionally especially on some of these cold mornings its blowing white smoke and is hesitating upon pulling off for the first maybe 1/4 mile and puffs white smoke.

I have attached two videos showing some of the symptoms. The glow plugs had warmed and light went off. Its about 40* outside. Coolant level seems to be remaining constant. The shop is thinking inj. o-ring or injector dumping/seeping fuel.

My 7.3 did that when my GPR wasn't working, but your smoke looks much thicker and whiter than mine did. Just because the WTS light is on and looks like it's working right doesn't necessarily mean the GPR is heating up the plugs. I could be way off here but it's worth checking out with a meter and only takes a minute. I broke one of the poles on my GPR while getting up onto the engine to pull the turbo. (At least I think I was the one who broke it, it could have been like that when I bought it.) Here's a pic...

interesting, i could check that out, where exactly is it located...

i figured it was working bc sometimes that light would stay on longer or less depending outside temp.

So unburnt fuel, diesel, is pure white, thats wild. I was thinking HGs.

GPCM is located on the passenger's side valve cover on the 6.0 ... I'd test to make sure it's working and that all of the plugs are within spec (for resistance).

thanks man i will check into that, will the haynes manual have the specs on the plugs or just check them and if ones out the norm change that one. so it def looks as if i have a fuel dump issue then?



btw i have a 1.8t gti, just over 400, the truck is its tow truck but i think its about sold to finance more enjoyable times in the truck lol...

Nice, 400 hp in a 1.8T. That's a pretty quick little GTI right there.

When checking the resistance on the plugs, keep an eye out for anything over an ohm (IIRC). If you have anything with infinite resistance, then it's definitely dead.

Ok little update. the guy hooked his scanner up and came up with 3 codes:
EGR low circuit (hmm i wonder why lol)
Glow Plug Cyl #2
ICP Sensor Intermittent
