If you want to use proper biodiesel, then you just need a normal diesel engine conversion(200 ro 300TDI best, but 2 1/4 or 2.5D's would run too, albeit with some risk to elderly Lucas pump seals). If you want to use veg oil (either new or well filtered/dewatered waste) you will need to do a...

Reg, and poss a receipt from seller. Or a validating letter/invoice from a selling/fitting garage etc etc. Think they're just trying to reduce the problem of defenders etc being nicked for engine conversions. Mark

Yes Engine changes are permitted. However you may have to give evidence of where the engine has come from. Mark

300TDI exhaust manifolds fit a 200 nicely and allow use of a straight downpipe,instead of the convoluted route needed to get off a 200 manifold. Mark

I've also seen conversions using a standard series 2 rad and using an external aftermarket oil cooler. Looked easy, and nowhere as awkward as a NATO oil cooler (which needs to go infront of rad). Mark

Attraction for TDI for me is that it can run on Veg oil/filtered waste oil or biodiesel without significant modification. Therefore even if I only get 25 mpg, the real mpg for me (on biodiesel) is around 250mpg, as my bio is made from free waste oil. I only pay for chemicals/electric to...

Yeah but in what proportions is best? Mark

Mnn Interested in what the mix of bitumous paint and wayoyl is?

cos it leaks on the road!

Defo worth doing as a set at that price, you can always keep any existing ones that haven't failed for spares. Mark

Yep that's what Molyslip suggest for theirs. Sometimes a bit easier said than done. Mark

Take the washers out and heat them with a blowtorch to anneal (soften) them. Let them cool slowly. Then put them back in. If that doesn't sort it, stick a bit of silicone gasket compound on either side of the washers before you bolt it up. Easy!!

Biodiesel yes. Biofuels - god know's they can be anything. Not a good route unless you're running a tough old TDI Mark

lots of pumps come up on Ebay cheap enough,but try and locate the problem. Likely its just a seal leaking, which would only cost a couple of beer tokens. Mark

Very good advice above. Mark

Screwfix good too. Can be mail ordered if not local to you. Quick delivery. Mark

Then you can enjoy the delights of being rained on inside the car, just like an old series LR. Mark

That's probably Adblue (or Mercedes equivalent) basically its just a urea (**** - yes thats right) based fluid that is used to regenerate the DPF. Used in trucks too. DPF's block up on all vehicles though, they are a way of reducing emissions on otherwise old engine technology. Work great...

Got a good reputation that stuff. Best bet is to fill your fuel filter with it, and have bugger all diesel in you're tank, so when it returns to your tank, it doesn't dillute much. Then take for a "italian tuneup" only topping up tank if you run dry. Biodiesel is also very good at...

I used spray on contact adhesive to fix carpet to the roof of my series. Works great Mark
