Definitive IDI WVO question

[jhax]

Hello,

I am curious as to if any of you with IDIs running WVO have a definitive answer to my question. Is it possible to run filtered WVO in our cars after changing the lines and fuel filter a couple times like this guy did http://www.youtube.com/watch?v=LIdnt7pic2M. I am not worried about the viscosity issue as I live in Phoenix, AZ and it's rather warm all the time. I was also thinking about running my fuel lines along my exhaust pipe for added heat. Are any of you doing what this guy is in his video? I am specifically talking to your 1.6 guys (1986).

Thank You,
Justin

anyone?

if you run vegi oil in a cold diesel, it will be dead in a short time..

the cold vegi oil does not completely burn. it leaves lots of glycerin behind after its burned.. the glycerin combines with the soot, and turns into coke.. coke builds up behind your rings, and effectively overbores the cylinders, then your compression goes out the window. the coke never leaves your engine, no matter how hot you run the engine. the coke will continuiously be there building up behind the rings..

once your compression is gone, the engine doesnt run anymore.. then its time to rebuild. hope that WVO saved you enough money that you can afford a complete rebuild of your injection pump, and engine..

so, you could either cheap out for 30k miles, then replace your engine, or you could run a 2 tank system (start up and shut down on normal diesel fuel) and be good for hundreds of thousands of miles..

people use a 2 tank system so they dont kill their engines, not because they want 2 different fuel systems..

the 2 tank system is the RIGHT way to do things, and not kill anything..

or, if you just dont care about your car, or what the WVO will do, then yea, go ahead, dump your tank full of vegi oil. see how long it lasts?

alright definitively answered

I've got a 2 tank system in my 89 with coolant encapsulated WVO lines and it seems to work pretty well.

In short, WVO needs to be at about 180* before entering the injection pump to prevent issues. Startup and shutdown need to be on pure diesel, then once warmed up, you can run on WVO all day long.

Need more questions answered, feel free to ask!

thank you sir. I understand. the temperature helps. It was just a fleeting thought. Im buying an 86 golf 1.6 later on i will be swapping out a TDI im building. but until that happens i figured i might run wvo but if it will be too much trouble it wouldnt be worth it unless there is an extremely simple way to run the dual tank system. i think the best idea would be to run the fuel lines right next to (by this i mean "zip tie" obviously without zip ties) the exhaust pipe to keep the wvo hot. And the only reason i figured i could run wvo without a dual tank was because i live in phoenix az where it is currently 106 degrees outside right now.

if it were 180* outside all the time, you could safely run WVO single tanked..
