I have seen several D3 tdv6's come through the insurance auction lately with a note saying engine damage, and a few more with under-bonnet fires.

Does anyone know what the common engine faults are, and why they catch fire under the bonnet?

andy,

Most likely suspect is incorrectly/ poorly installed fuel filters. These sit on the lower crossmember not far from exhaust etc:o 1 leak and I can see the flames from here:( A pretty bad design IMHO, they aren't the easiest of things to fit if you haven't done one before and have average aptitude.

I have heard of 2 fires. No idea if it was people badly wiring a second battery or what. Not a significant issue as far as I can tell. Sure someone will be along soon to give us the right info!!!

The D3's don't like running out of oil:o So don't let your oil run out:p That is the most common engine problem as far as I can tell.

The other concern is misfuelling of diesels. If one fills with petrol and let it run, certain parts, (fuel pump I think??) need changing, or after time has passed, certain parts deteriorate and break up, and this can cause chaos in the motor.

land rover is having a safty recall of a very few d3, what it is that the highpressor pump at the back of the engine, the seals wernt up to the job,

intern leaks fuel an that gose all over the back of the engine were the crossover pipe is for the turbo is, (exhurst from the right bank to the left an into the turbo) witch is very hot an with enogh fuel up it gose,

i have seen a few cars that are driping fuel from underneath the car, an if that dident catch fire, it must need alot of fuel, for it to go up in flames,

an if you put petrol in it an you would be serprised how meny people do, an 8-10 drive them till they stop:(, but this will need replacement of all the high pressour side, (injectors,pump,pips,ect) an the fuel tank an the rest with a clean out,

in short VERY EXPENSIVE, an its alot worse for a tdv8, cos you wont get much change from $20,000 with parts an labour, so its a very pain full way to learn:p

JC, will diesel ignite without being under pressure?

i have seen atleast 6 burnt, and 3 of them were underbonnet fires, the others were totaly gone. There was a freelander 2 that went under the bonnet aswell. No RRS or L322s yet though.

Why would a newish car use soo much oil that they would run out?

anything that can burn will do so if you get it hot enough!

Yup, like Sprint says, enough temp will do it. Taking into account the temps downstream from the turbo and dump pipe when under load, 500+ degreees isn't uncommon:eek: Don't forget the Cat will be superheated too....a fine mist of diesel will be fatal:(

The fuel filter is on the opposite side of the transmission to the turbo and exhaust pipe as I have just fitted an extra filter with water sensor because the early models did NOT have a water sensor. :angrylock: It is not overly hot at that location but as you say changing the LR filter is fiddly with those fuel line connectors :( and they could pop off if not done properly :(
