Also, the other close up photos of the WVO injector parts. [brief description] The honey colored goo coming out of the fuel feed hole was the consistency of honey or pancake syrup AFTER an two hours in a hot ultrasonic cleaner. The spacer disc appears to have small bubbles on it. These were hard and gritty but much easier to clean. Gentlemen, you have the photographic "proof" of polymerization of WVO in a fuel system.
My personal opinion is IF you use WVO, use it as stock to make bio diesel and clean it meticulously. If you use diesel fuel, get it at a busy truck stop, use your own cans and filter it before putting it in your tank, when possible. |
I looked at the pics in post 21 of the thread you linked to. My nozzles with 40K on WVO when replaced with Monark nozzles does not look like the poly gummed up nozzles in that pic. Mine were nice and clean with just a slight bit of carbon at the nozzle tip. Are those gummed up nozzles in you pic from a single tank sytem where the engine is started and shut down on VO? I purge with diesel on shutdown and my VO is very clean and that keeps the injectors clean. My filters last a loooong time.
Biopete, is the single tank system on the TDI?
