Easy solution....don't wear any

Hope ur good at changing half shafts!

Hmmm...yes...ive been pondering a diesel v8 for my disco. One day...when ive finished all my other projects (my rr/109 hybrid actually drove today....most exciting!) Anyhoo...it was a passing thought after too much to drink last night. There are far better engines out there

Not sure how this topic came up last night, but it got me pondering..... Now...the series gearbox isnt going to last long on the end of a V12, and assuming you can get hold of whatever adapter plate you need, what would you do? - Use a permenant 4x4 gearbox....then what about the UJ problem in the front axle? Freewheeling hubs? - Replace axles with defender axles? - Use the jag autobox, and add a seperate transfer box? Any ideas?

Oi! It was 25 and in two months.... I did manage to blow the fuse though by pushing it a little hard...survived though! I have a cheapo draper one too - gets just as much abuse and still going 2 years on!

In short...when idling your exhaust is still full of air. A proportion of this air is recirculated into the intake to doubly burn the nasty stuff in it. Emissions control stuff..... It wont decrease your mpg, but it does tend to clog up ur intake manifold over a period of time. Ive just pulled the vacuum hoses/electrical connectors off mine. Stops it working just nicely (and its cheap)

Wow...wish I was brave enough to do that! Good luck!

It is also the feast day of Saint Florian - the roman catholic saint of firefighters. He was commander of the Imperial Army (Ok..so it was the Roman Imperial Army, and in eastern Bavaria...but it still sounds a bit star warsy...)

Interesting that the numerical date is 04/05/06 - which are also the numbers of the original stars wars trilogy.

Please dont say that. Its the veg component that will not atomise correctly - it congeals into blobs rather than a fine spray. Most likely, that because you have quite a high percentage of diesel in the tank, it burns first, then assisting the veggy. I would very much expect you have lube oil contamination. The reduction in combustion efficiency will not be measureable by mpg...I found I would loose about a litre of fuel into the lube oil every 1.5k miles or so - this equates to a reduction in mpg of 0.0006 (my blending experiment - 60% veg, 35% diesel, 5% petrol). This however, is more than enough to turn your lube oil into jelly (been there...done that....) Also remember that the remainder of the veg is not simply "not combusting", but partially combusting - only a very small percentage will condense onto the cylinder walls. This will still result in a dramatic gas expansion and provide power.

Yes...especially after the lovely job you did on Bob (It undid by hand virtually.....)

And I ran that same box with an uber-mega tuned 3.5 on the end for another year....and its still going (I have a heavy right foot).

Ive heard of lucas injection pumps seizing on as little as 15% veg. These really are very fragile. I wouldnt risk it. And its not just the FIP you need to keep happy - Direct injection engines will suffer from piston ring coking and polymerisation of the sump oil if veg gets into the sump - which it inevitably does. Ive had this on my 300TDi - if your sump level starts going up...do an oil change quick! The oil came out in lumps on mine. This is especially true if you have tweaked your injection pump for increased fuelling. If you are not too worried, then id say 30% blend in a TDi is fine...however...keep an eye on your sump level, and keep your injectors clean!

1. Biodiesel is fine for stopping and starting. Two tanks is only required for veggy. 2. Absolutley. If you intend to make biodiesel, you have some VERY nasty chemicals as well as heat+fuel. The potential for fire and chemcial damage to both yourself and your property is huge. I make mine in the garden, and use googles+face mask+gloves at all times. I think the neighbours think im a bit odd Filtering waste veggy though is pretty safe. Vegetable oil is reluctant to catch fire at the best of times. I have thrown lit matches, and blowtorches at a drum to prove to my housemates that im not going to burn the house down!

Hmmm...I was under the impression that they were the same engine. It might just be the fuel system thats identical then. The electric fuel pump in the tank is a major stumbling block. The additional tank must be used for veg with a more robust fuel pump...with the same ratings as the original.

Actually...smartveg have a couple of Tourans converted. This is the same engine as the td5. Its a question of fooling the electronics too. Might be worth giving them a ring. www.smartveg.com

Im new here...but spotted this thread. I have run a 2.25, 2.5TD, and a 300TDi on veg oil and I run this forum on the subject here: www.vegetableoildiesel.co.uk/forum Most land rover engines can be made to run on veggy quite happily...however all of them require a 'twin tank' conversion. The idea being you can start and stop on diesel and change over to veg when the engine is hot - and by using a heat exchanger in the fuel line, you can ensure the veg oil is hot and therefore wont kill your engine. The 2.25, 2.5, and 2.5TD all have lucas injection pumps. These have proven to be quite fragile on veg. If you use veg in these engines when the veg is cold, you will deprive the pump of lubrication and the rotor head will seize, either breaking the timing chain, or shearing off the drive shaft. Either way...its nasty. The TDi engines however, have a bosch injection pump - these have proven to be quite robust on veggy...however the fact that they are direct injection poses a new set of problems: When the engine is cold, the oil will not burn correctly (if at all on a very cold morning) in the cylinder. It can then condense on the cylinder walls and will both cause coking under the piston rings, and get into the sump oil where it will cause a chemical reaction that will polymerise it. Again...not very nice. I dont know much about the TD5...but it will require a twin tank again. I would probably give it a go if it was mine...but I wouldnt advise anyone to try it! Have a look in the archive section of the forum above. There are some posts in there that explain things a little better. You could also look here: www.inhislandy.co.uk and click on 'veggy pages'. Mostly geared towards land rovers. As for making biodiesel...in short...heat it up, add a methoxide mixture made up to the correct concentrations and volumes by doing some calculations and titrations on the oil....mix for an hour or so...wash...dry...put it in your landy! Customs and excise will also want a slice if you are in the UK and your landy is road registered (doesnt matter if it is only used off road...if it has number plates, the fuel must be taxed). Technically the tax rate is 27.1p per litre for both veggy and biodiesel, but there is a bit of a fight going on at the moment.... Any questions?
