Looking for input

Hey all…been lurking for a bit and now looking for input. I’ve got a list of items that I need to replace on my ‘06 6.0 and all of the parts to complete the list. My question is this, what order is best to complete each task and should I complete each one individually and ensure I’m running again before doing the next?

1. 8 stock reman injectors/oil rail rebuilds
2. Blue Spring Kit
3. Oil/Fuel Filters
4. Coolant Flush w/ New hoses/aluminum degas/thermostat/coolant filter kit (Cat ELC)

Thanks for any input and/or tips you can provide! ~Hondo~

Personally, I say the oil and fuel filters are easy and just general maintenance, do those first . Second blue spring. I'd do the coolant flush third because there is a possibility it'll completely clog the oil cooler requiring an oil cooler replacement, if that happens , you can do the oil cooler replacement while you've already got the engine torn into for the injectors. Just an opinion , they're separate projects you can really do them in an order you want, but I would do the coolant flush before the injectors.

Is your coolant system plugged up now?
What do your oil and coolant temperatures run after the engine is completely warmed up? On the highway? Towing of max boost?
Any evidence of hard solids and/or corrosion, or any semisolid material present?

You need to know these things to determine if you might need a chemical flush, or something less aggressive. Not plugged at all, and you can probably get away with just distilled water flushes. If there are hard deposits and rust, it would dictate one type of cleaner, and gelatinous semi-solids would dictate another cleaner type. If you have oil or fuel in the coolant, then those are going to be more involved processes.

Not only doing a fuel regulator spring upgrade, you need a fuel pressure gauge to do the best job at protect expensive new injectors.

Oh, and if you actually have an oil cooler leakage issue now, chemical flushing of the coolant system may not be best before eliminating the path of "communication" between the oil and coolant.

All about the details.

Temps are running 180/185 and I’ve never seen either go over 195 when towing. Coolant system isn’t clogged and no signs of sludge.

I should’ve prefaced this with some info. The truck had a top end rebuild and coolant flush by a shop in ‘18. The injectors were not part of that as they tested out fine. In the last 3-4 months I’ve had contribution/balance codes on #3, #6 and #7.

Knowing it’s time for a coolant change I wanted to change over to ELC. I also know that the remaining injectors aren’t far behind and planned to do all of them at one time. I just hit 190k.

Good deal, flush w/ distilled water and you won't have any issues.

.

those are like perfect numbers especially while towing

however it’s set up id consider keeping it that way seems to like it

I might catch some $#|> but in your case with numbers that good if I’d drain and fill only no flush
