Biodiesel can be made from a wide range of raw materials: Cooking oil, Switchgrass or animal fat (soon also Algae!). Unlike ethanol it is particularly suitable for waste products. Because it is so versatile it is therefore also possible to make it from "wrong" kinds of raw products. It's also possible to make it from the right kind of raw products. The choice of raw materials doesn't make biodiesel production in itself good or bad.

It is the underdog of biofuels. Unlike the scam that is ethanol it is actually good for your engine (solvent and lubricant). Even though it is a superior alternative, vested interests wants it to go away because it is so easy to make. For $1000 you can start your own refinery at home. Hard to monopolize a fuel that anyone can make at home. That is why the oil companies in Texas and elsewhere are trying to get it banned.

As Chip (sorry for picking on you again, Chip) and others have shown here there's a lot of myths yet to be dispelled about Biodiesel.

Here a good fact sheet: http://biodiesel.org/docs/default-so....pdf?sfvrsn=16

From the fact sheet: "New cropland is not needed to make biodiesel because it is produced from co-products and byproducts of crops already grown for food and other materials. From 2004 to 2008, when U.S. biodiesel production climbed to 700 million gallons, soybean acres in the U.S. stayed virtually the same, and soybean acres in Brazil decreased. There are surplus stocks of U.S. fats and oils sufficient to meet demand."

I mentioned Palm oil because it is the vegetable oil that currently is contributing to the rain forest destruction as you implied. Although it can be used for biodiesel production it is mostly used for other products.

The places I had looked up and had mentioned in the Portland area say they use recycled cooking oil. Is this the case with all biodiesel?

That article refers to Biofuels which is not necessarily Biodiesel. It very well could be and is likely to be Ethanol. Different fuel, different raw materials, different impact.

Same as above. Biofuel doesn't necessarily mean its Biodiesel. Biodiesel is very different from Ethanol.

I'll make as separate post about NOx emissions.

And Texas has been trying to ban biodiesel use for several years because of NOx emissions.

NOx

I'm starting to feel bad about the highjack, Ben so I'll keep it brief.

Californias' (and Texas') myopic focus on NOx is misguided. The first graph shows a Carbon Dioxide per joule of energy comparison. The second one is a snapshot from Oregon DEQ.

Yes. In B20 (20% Biodiesel) there is a 2-4% increase on NOx but all other emissions (NOx is only one component) see between 10-20% reduction. In B100 which I run there is a 10% increase in NOx but there is also a 47% reduction in unburned hydrocarbons, 67% reduction in Carbon Monoxide, 80% reduction in greenhouse gases, 100% reduction in sulfates and 80% reduction in Polycyclic Aromatic Hydrocarbons.

Can you spell red herring?

Good stuff. As I mentioned, I brain farted and was mentioning the issues of deforestation in thinking about ethanol -- my mind has not fully grasped the diesel life, yet. And further above I had mentioned that I had earlier looked into what it takes to make your own biodiesel, and had researched out the places in Oregon that sell the stuff from recycled cooking oil.

I'm planning on running bio, probably B20, but I'll mix it up from there when I get the chance.

The main reason it came up is because it was years ago that I first looked into it, then I seemed to remember some bad press about it with seals and gaskets, so I was looking for that info in particular.

I remember diesel Shoguns/Pajeros a while back having a fan on their intercoolers...not sure how affective they'd be?

Have a wee peep here.

Maybe one could be adapted to see if it made a difference if one was interested enough?

All the best

Good evening Uncle Douglas

The John Deere part number for the viscous fan pulley bearing in the timing cover is JD9257


If I can direct you to read over this thread you should find it informative

Post number 20 is interesting.

300tdi Viscous Fan Bearing - SOLUTIONS! - Page 2 - Australian Land Rover Owners

If Land Rover just made the price of a new cover reasonable they wouldn't loose out in sales by people doing it themselves.

I have two timing covers in my workshop that have bearings that need to be replaced at some point. The last one I got was from a chap off ebay in the UK whereupon he had sourced a limited supply of Jaguar bearings that worked.

I hope you find the info useful.

All the best
