Hi all,
I have been watching this site for awhile but I just registered and thought that maybe you could give me a hand (or a few pointers).
I have been working on running WMO for a little while, mostly I was trying to get my filtration setup down.
I have now started WMO85% / RUG15%
After about 600 miles I start to have some smoke at idle/cold and after ~1500miles it smokes pretty good (white smoke) at idle, but it runs great once you get the heat up on the freeway, uphill, etc.
About 2 weeks ago (1500miles) I pulled the injectors and they were all coked up. I cleaned them, reinstalled and once-again idle was smokeless. I installed a water injection system (I had parts lying around). I started using a 4GPH injector set to come on after 10PSI, but some 600miles later I start seeing some light smoke at idle and I changed the injector to a 10GPH injector.
I am now about 1500 miles out again from the last time that I cleaned the injectors and I have consistent white smoke at idle, but performance under load is great. I am pretty sure the injectors are coked up again. I have tried some WOT runs (2200RPM, 1100DegF, 25PSI) with the water injection, and it just doesn't seem to be giving the cleaning that some people are taking about.
I am about to pull the injectors for the second time to clean them. Anyone have any thoughts on keeping this from happening? I really thought the water injection was going to take care of this.
As a side note, the truck runs great on D2 and starts right up every time, regardless of temperature. I have not done a compression test, but I have no reason to think that anything is less than great with this motor.
Here is a picture of my injector (worst one) that I pulled to clean.
