2 Bad Injectors

I had all my injectors cleaned and bench tested last year. My truck was running awful and I had them pulled again. I had 2 bad injectors that were gunked up and couldn't be cleaned. What can I do to remedy this situation.

I run WVO. I centrifuge it and let it sit.

Do you run heated WVO? If not, you might need to research blending.

Send a message via ICQ to sandfun
i have a few ideas that pop to mind.

have you or do you ever run wmo also,theres your problem
do you use a 2 tank system,starting and stopping on d2 ??
your cleaning process,has a flaw.better go over it again and see where it's broken
your injectors were from a crappy e-bay, re builder,and would have failed on d2 also
you starved and scored the injectors by clogged in tank fuel screens,better do the hutch mod.

If you have a GFS then you are 2 tanking.

In order to help you need to provide more info.

How do you process your oil? I know you said you centrifuge but do you heat the oil? If so how hot? How many passes? Do you check for water after processing? If so how? HPT?

How is your conversion set up? What micron rating is your VO filter? Are you sharing any of you stock fuel system components?

What is your VO operating temps?? You should be running at least 160F. If your not then that would definetly cause coked injectors. Do you purge before shutdown? If so how long & how long are you running the truck after purging before you shut it down.

The most common reason for coked injectors on WVO is low veg temps or improper purging.

No. I do not run WMO.
Yes. I do start and stop on D2 and have a 2-tank system.
I have already done the Harpoon and Hutch Mods.
I don't have re-built injectors.

Yes. I do heat the oil to 160 degrees. I run it for 3 hrs, 30 gallons at a time. I assume since it does 55 gph it is making quite a few passes.

No. I do not check for water after processing. I expected the heat from centrifuging to burn most of it off, as well as the water separators to collect it.

I have a 2 micron filter and the pump is shared for both D2 and WVO.

I do not know the oil before it hits the truck. I have a 201 or 210 degree thermostat and I wait for the engine to get to full operating temperature before I switch over.

Yes. I purge before shutdown. I switch as I'm getting off the highway and my truck runs for about 10 minutes and 2 miles up and down hills and in traffic. I can't say I'm always perfect though at purging.

Could you describe your conversion setup in more detail? What components you have & how it is plumbed? Are you sharing anything else other then the pump?

You should check your oil for water. Just because your heating the oil doesn't mean your getting all the water out. Every batch is different as well. One batch may dewater fine & the next may not.

I would also suggest that you get some gauges. You should really have a VO temp gauge & a fuel pressure gauge. Your conversion may not be providing enough heat to get the oil to operating temp.

How many miles did you get before you started having problems again?? How many miles is on the injectors??

What is the Harpoon mod??

It's actually a 203 degree & that is the engine t-stat.

if you really want to know fuel temp only way is PTC or NTC senzor-meter.

What is that senszo-meter?

I was told that these electrical injectors can't handle veggie oil? Is this true as I've never heard it before.

There are many guys that run hundreds of thousand of trouble free miles running a 2 tank conversion. Most people that do have problems are either not dewatering their oil well enough, not running the oil hot enough or at the right pressure, or not purging long enough.

The injectors will handle vegi just fine.

Simone-

I have a 60 gallon trekker tank in the back which has heated coolant running through it w/ a 203 degree thermostat from the engine.

I also have an 87 watt heater wrap around the oil filter and that is wrapped in insulation as well.

The fuel line down to the valve switch is insulated too.

What else would you suggest for heating purposes?

Where would I want to put a thermostat? Up near the engine bay?
