More Duramax info

Ford injectors are oil activated, not cooled. HPOP = High Pressure Oil Pump. It's what builds the pressure for the injector to fire/pop.

For 60 bucks, I'd still give HSS a try. A whole lot cheaper than injectors. Nothing to lose. HSS works in all diesels though it was originally designed for the 6.0 powerstroke.

Wow. All these problems you speak of. I'll stay away from Duramax!

on my third 7.3 Ford. All together, 1.3 million miles combined. 2 turbos, 4 tranny's, about $3k in front end work. Glow plugs, batteries, hoses, belts, tires, and a water pump here and there... No engine work. Ever. I do need a tranny rebuild now though.

Rotella T every 10k miles
fuel filter every 30k
tranny and rear end every 50k (manual)
4" exhaust with turbo muffler (no cat)
napa 6637 filter
Edge Tuner on 1 (Towing 60hp)

I didn't know ford had oil cooled injectors, makes more sense now. I would still think something pored into the fuel tank would have more of an effect on the injectors by flowing through them.

This doesn't apply to dmax injector as they are not oil cooled like your ford.

What does adding something to the oil have to do with injectors?

Go to Hot Shot Secret's web site for detailed info. In a nutshell though, it cleans the burnt on oil on injectors and in turbo. This burnt or caked on oil is called stiction and basically it plugs the tips of inj and bearings in turbo. If you removed a "failed" inj, chances are the inj itself is still good, just the tip is plugged up.

a good fuel stablizer to prevent algae growth would be good idea...and for me if my truck sat as much as your's it would be getting the filters changed that often too...one thing to look out for if four wheel drive is the dreaded transfer case pump issue on those trucks.. i have repaired three of them from it one required a whole new t-case..as for the injectors they could go for another ten years or go out tomorrow..and depending on the year of your truck it is either terriblely hard or not to bad to change them.

filters are fluids are all you can do to take care of the truck. Injectors, turbos and head gaskets are all the expensive possibilities but it's largely just luck. Not chipping/modding the truck to the gills certainly helps your chances of not suffering a major repair but nothing can totally eliminate it.

I'm at 130K and have just had the normal (and sometimes expensive) front end parts, leaking tranny lines and a xfer case. I'm hoping to get another 50K miles without one of the "big 3" going out but who knows.
