Hi again TDI Club haven't posted for a while. I'm looking to purchase a car and am considering 99-mid 2000's as choices. I would like to ask if the PD is a better choice than the ALH for engine type for fueling with WVO or Black Diesel. I thought maybe the individual injection units on the PD engine would eliminate at least some of the strain on the main fuel pump.

Thanks and any comments especially well know and tested mods to either engine type say aftermarket fuel pump for ALH engine concerns with any other fuel system components when using fuel with higher viscosity. I will alternatively research further the topic in the forums. Thanks

I have converted two Jettas, an ‘02 and an ‘06. The ‘02 was easier, because you don’t have to be concerned with an electric lift pump. Otherwise both ran well for a long time on WVO.

Phil a number of questions for you. You say they "Ran" for a long time being did run and not anymore? How many miles on the engine once converted and how many post conversion?

Single tank or double tank? Did you use a commercial conversion kit or build you're own? Did you do any mods outside of what was suggested if a purchased kit. Did you follow any suggestions or procedures of any members of TDI Club?

I have read the write up by T's TDI on WVO conversion and found it informative if perhaps slightly dissuasive. He explains how to execute a work around for the fuel temperature sensor that I believe is likely one of the most important areas to consider relative to timing. Did you use any timing mods etc.

Both ran well as long as I owned them. The ‘02 I converted at 75K and ran to 275K, I think. It was pretty beat up by then; I sold it to someone who mostly wanted the engine and transmission (5 speed). The body was banged up and the interior was worse. The ‘06 I converted at 80K and ran to about 225K when I stopped driving long distances and traded it for a Leaf.

Both cars had Greasecar 2 tank kits. The only significant modification was a Vegitherm electric fuel line heater, which allowed me to add some additional heat when needed. I was aware of the temp sensor mod, but never did it. My cars seemed to run just fine, with no noticeable loss of power, so I didn’t bother. I also vented the tank overboard, so an overflow wouldn’t make a mess. That probably reduced the smell in the trunk too.

Probably at least as important is the fuel and filtering. You need a reliable source of decent quality oil, and you have to filter it well.

When you said "ran to" that is misleading. A more accurate description would be (had x number of miles when sold) I'm looking for accurate information to make informed decisions on conversion. To say having a consistent supply of of oil seems a little unnecessary unless such is in regards to the effects of aromatic compounds on stock fuel pump seals.

I don’t see anything misleading about “ran to”, That is exactly what you asked, and exactly what I did. If you are looking for more information, just ask. As I said , the number of miles I “ran to” is when I sold it. What do you find misleading about that?

I don’t know anything about aromatic compounds and fuel pump seals, so I didn’t say anything about that. I do know that you need a reliable source of decent quality oil, so i told you so. That is in fact true, and more than a few people have converted their cars, only to learn they can’t get enough oil. That is a mistake, and one you would be wise to avoid.

If you have any more questions, I will be happy to answer them also, if I know the answers.

What mileage could be typically seen where turbo needs rebuild/replacement and what problem(s) could an early turbo replacement on a factory stock or close car be indicative of outside of say oil starvation from a blockage or leak.

There are numerous things I know niches type specifically detailed but don't know a lot of the common things. Just recently (in the last couple years) learned that biological material can grow in gasoline and diesel. That was crazy to me.

I don’t know how long turbos last, but I’ve seen very few fail. I never had an issue so a couple hundred thousand miles seems a a good minimum.

I do know about stuff growing in your diesel. Or WVO. I used to add a biocide to my WVO storage tanks. It is designed for diesel, but seems to work fine for WVO too. I never had a problem after I started using it.
