Big Problem with fat in IP!!
 

This is not for my 300D, but for my friends Dodge 2500 Diesel Truck.

he got some oil from a restaurant hot, and filtered it hot through his oil filter that was inline with his pump. he then blended it and this all happening the same day added it to his tank while still hot.

it ran fine while it was hot that day, but the next day he died 3 times trying to get his truck home. replaced the filter once, and it was covered in yeloow/clear fat. the whole filter element was covered in a 1/16th inch layer of it.

SO.....

i came over and we first drained the tank. (it was yellow thick crap) then empied the fuel filter again (his 3rd) and filled it all with diesel. tank has 2 gallons in it, and the filter is full too. we then plugged the block heater in for about 4 hours until the engine was hot, and we also took heat guns and were heating the IP lines, the IP and the injector ends.

It would not start. we had to get my 300D next to it, and have it hooked up to a battery charger to keep cranking that IL6.

Still will not start. so is the IP soo full of fat that he has to take it out and clear out all the lines going to each of the cylinders? what better way to heat it. we might go and buy a pipe heater cable, and wrap it around the ip, but cranking it for over 2 hours and heating it has given not even 1 almost start situation. always just cranking over. i think it is dry, with his system i cant pump and bleed myself. it is all automatic with his system. we can hear and know that the fuel pump has diesel in it, but i dont think it is getting any of the diesel.

so i really just need more ideas of what we can do to get it started again. i know this is the wrong forum for this topic, but you are all diesel freaks.

he has learned his lesson. no filtering suggestions, he knows what he did wrong... now:(

No lecture, But boy do I want too.:)
I am not familure with the Dodge fuel system. Does it have a electric pump?
I would suggest pull every thing including the injectors and clean in diesel or another soulvent, main thing is get diesel back in the whole system, may be forcing it wit the pump. Or some sort of electric pump to force diesel thru the system, that FAT will be hard to remove even on the inside of the IP, and lines.

my 2 cents -
1 - get it into a heated garage
2 - put a space heater pointed right at the engine and IP
3 - pour a couple of buckets of boiling hot water over the IP
4 - temporarily run straight petro-diesel to the IP from a plastic bottle with an extra piece of fuel line (maybe even DP)
5 - give it a go - if everything is good and hot then it should start on the fat and then run the diesel purge through...

Did your friend use hydrogenated oil?

sounds like he got a load of chicken fat......:eek:

the fat was from Chick fil. 100% peanut oil, but burned for 1 week. so it had a lot of fat in it. when he gave me my hand pump back, i set it down so it could drain on some wood, and the next day there was a 2 inch circle of wax density oil. very hard.

i know i know, i filter my oil more, and he though he was getting good oil because it went through his filters so fast, but because it was hot, the fats were melted.

i guess we just have to heat heat heat.

I know nothing about this.....
 

I am just guessing... but isn't there some kind of saponification process necessary to prep this stuff before using ?
Or some acid precip or something... ?

This sort of crap is better suited for making biodiesel than direct use as WVO....animal fat doesn't do will in a WVO system outside of death valley in summer.

what year is the truck?? Is it a 12 or 24 valve?

thanks

maybe he will sell it real cheap?:D :D :D

filter it COLD--
 

that way you might get more of the chicken fat nasties out of it. Ther last thing you needed was to get the fat INTO suspension ans all thru your injectors & pump.

Also, Diesel + WVO = wax precipitating out of soultion and depositing itself all thru the fuel system.

Us Benz guys that run filtered WVO cut it with regular gasoline, about 20%- but I don't know if the Cummins can take that. Best educate yourself by researching what the Dodge boys do before attempting another refuel with WVO.


Let us know how it goes, this looks like a real learning experience!!

I'll give your buddy $100 for his truck the way it sits....:D

lol, i cold filter, and i am running very very clean wvo that i filter from 25u to 10u and then to 1u. i know about filtering, but he did not. all i knew is that he was getting a new source when he had it in his truck already. he told me when he was already stuck.

he has a 1998 i think. not sure how many valves, but he has his tank, then a pump, then his filter then to his IP.

Want to bet he never skips cold filtering again?

I thought that grease had to be processed before it could be used...

i get my oil from a chinese restaurant that has very very low amount of fat, most of the time when i cold filter there is none in my filters at all. his was ridiculously fatty. to him it looked fine because it was hot and clear. normally you should just avoid all fatty oils and look for better oil. if you by all means need to use it then you have to settle it for weeks and then cold filter it later.

now we just have to get his truck running again...

Glad its not mine............

bet everything is coated with a thick layer of congealed chicken fat....tanks lines, everything....thats going to be a royal mother to clean out.:eek:

Your best scenario is to find a garage. Use two or three portable LP heaters and attempt to get the garage up to 100°F. It may take some time and a decent amount of LP, but if you can get the underhood temperature above 100°F, the truck should start. I'd get it running on diesel fuel and blow all the lines completely clear with compressed air before moving it out of the garage.

Scary stuff...WVO
 

I have been seriously considering modifying my 85 300D to run on WVO. However, with these types of situations popping up on this forum, I'm getting cold feet. Although it appears a good coversions setup and proper filtration is key, I'm not sure the risk is worth it.

So, what's the verdict? Are there WVO conversions out there with high mileage on this setup without issues if you you follow the book? Is there a bottom line consensus "all things considered"?.

you will get as many different answers as people who answer unfortunately...

i condone WVO totally. just not when you do stuff like this. you need to always let your oil settle. then cold filter, and just not be impatient. i use it with out any problems, and he was just too excited about his new oil, and he was running on E.

Man, I'd never put any oil used to fry meat. I have no problem with meat to eat, just not for my diesel. Too risky.

Thats exactly the sort of thing that has kept me from dabling in the WVO world....I've read so much the more I read the more I can see that could go wrong..(to me anyway)

I want to do Biodiesel but haven't gathered the stuff to build the processor yet.

you can run on straight oil. you just need to keep it warm enought to move through your system. The origianl diesel motor was built to run on peanut oil.

Sounds like the Warhorse scenario (http://biodiesel.infopop.cc/groupee/forums/a/tpc/f/159605551/m/563103245/p/1). Mixing wvo and diesel in some areas/climates/moon cycles is bad. Don't do it. Do not do it. Just say no.

If it's wax, I am sorry. If it's fat it will melt easily. If heat doesn't do it, I'd guess fat. Don't mix diesel and wvo.

Read the thread...

Read that one a good while ago.......long read but informative.

Heat gun towards IP...watch not to burn anything.

LMAO at your comments..did you interrogate Iraqi's in Cuba...lol.. it would have sounded like this.......

Hey harry..plug the electric wires to the bedframe..and put ol' ahmed on it first...and if he doesnt talk..just run the juice up a little...shucks..ok lets stack them in a pyramid on the floor....Ahmed I am going to use that turban as a pull-starter for my lawn mower...Oh and for dinner..Porky Pig..oink oink

Oh trust me I could dream up better stuff than that.....:D If I was given a chance.....:eek:

got it started, the problem was not the fat anymore, the IP was totally dry. we made a makeshift tank and supplied it with diesel. started up after 20 mins of feeding it little by little. he is happy, and not as stupid. lol

Im pretty sure animal fats (normally found in grease traps) need to be "washed" (with a strong acid) to seperate the glycerol and water out of them. Isnt this called an estherification process or something. You really dont want to use old oil used to cook saturated fats (those found from animals) unless you do all the processes needed for biodiesel. I imagine clean, uncooked, peanut oil would be fine though.

The big mistake was a blend with this type of oil. With a proper two-tank WVO system you could run LARD if and only if you can heat it up enough to flow through the lines and pump. Provided the WVO is properly dewatered and filtered, correctly heated there should be no problem. When blending NO animal fat is allowable. This is the kind of stuff that gives WVO a bad name. The principle is sound but the execution lacks. RT

I've 60K miles on my '92 5.9 cummins running a wvo/diesel blend out of a total of around 400K miles.
No heat, single tank. I vary the blend as ambient temps change. Up to 95% wvo in the summer. Around 50/50 now to be on the safe side in case we get a cold front come thru.
No problems so far.
Cummins are tough to start if run dry.

BTW, best yet on the blend was 24.7mpg. GPS verified milage, 1ton dually.
I'm afraid my source of oil is going away though. The resturant owner lost her lease. Time to beat the streets searching.

I know you were joking but misconceptions like your turban on Iraqi's led to many Indians getting attacked after 9-11.
