    can I prevent coking with WMO?

    2 Tank is probably the way to go. I just was hoping to get by with blending without too many mods to my truck.

    can I prevent coking with WMO?

    Good one. :) However I tend to classify winter as below freezing, and yes, where I live, The nights in the winter, and sometimes throughout the day do get below freezing. I am sure that some of you have run a lot colder than I do though, I had about a month where I was leaving for work in...

    can I prevent coking with WMO?

    I have not tried that yet, but I suspect that my injectors are a little tired, as to my knowledge they probably have over 300kmiles. On diesel they run fine, so I have not pursued changing them.

    can I prevent coking with WMO?

    I do not have sufficient data on that question yet. However, even in winter, if my injectors are clean, there is no smoke. I suppose the real question is, do I have more/faster coking in winter vs. summer, and I suspect the answer to that question is yes.

    can I prevent coking with WMO?

    I believe they pull somewhere around 220A @12V, but it is cycled, not full-time. This is an interesting thread discussing the topic: http://www.thedieselstop.com/forums/f33/dodge-cummins-intake-heater-grid-s-183104/ This is very interesting and shows that your motor uses a significantly...

    can I prevent coking with WMO?

    FYI with my motor 5.9 Cummins 12Valve, if I have good clean injectors I can burn 100% 80/20 (80%WMO, 20%RUG) without any smoking, even at idle. The problem arises after about 800-1000miles of burning the mixture and I begin to get white/grey smoke at idle. I have proven that I can pull my...

    can I prevent coking with WMO?

    The 12Valve Cummins I run is a direct injected motor that does not have glow plugs. Alternatively for cold starts, Cummins used something called a grid heater which is mounted in the intake manifold. It is basically a big resistive coil that draws power from the electrical system and only cycles...

    can I prevent coking with WMO?

    Blownoiler, There is no way to change the fuel/air mixture (use less fuel at a particular boost pressure). These are un-throttled motors. They always flow as much air as possible. You add fuel to make more power. Less fuel produces less power. We don't have any control over fuel/air mixture...

    can I prevent coking with WMO?

    Just a thought on the heat exchanger topic. Once the motor is up to operating temperature, normally the fuel in the lines is already warm from the pump, and since the injectors are mounted into the engine block and are protruding into the combustion chamber, they are essentially heated all the...

    can I prevent coking with WMO?

    One more question: Coking on Injectors is one thing. You get smoke and it is nasty, no major harm done. Has anyone in the WMO scene ever had major engine damage from WMO? Not injection system, but engine? I am thinking coked rings, leading to cylinder scoring, injector coking leading to...

    can I prevent coking with WMO?

    I saw an interesting trend the first time I pulled the injectors with the #2 being by far the worst, followed by #1 then the others... The second time I pulled them, they were a lot more consistent with #2 actually being a tad cleaner than some of the others.. I was thinking that if one...

    can I prevent coking with WMO?

    EGT's are lowered about 100-200DegF. So if I am running 1,000DegF I might see 850DegF with WI. Right now we are above freezing so I have been running water only, no meth. I am now trying my 50/50 mixture and the jury is still out. No smoke yet, and I am at 600miles.

    can I prevent coking with WMO?

    The worst injector was not quite as coked as last time, but over all they were just as bad or worse.

    can I prevent coking with WMO?

    One the the big reasons that I chose WMO over WVO was that I didn't need to heat or run a two-tank system... I was under the impression that blending (RUG, etc) would solve the viscosity issues and it could be run successfully on a stock truck in very high percentages.. As a followup, I...

    can I prevent coking with WMO?

    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%...
