We had this on our 200 Disco, same symtoms after veg oil, swapped all the fuel pipes and that cured it ( its cheap to do ), Veg oil cleans all the crap through your system,
had a similar thing on my 90 when driving down to stoneligh last week for all those who saw me with my bonnet up by the side of the M1, i was tightening up the fuel filter which cured it,
sounds like air in the system, or crap lodged in some where try some wurth diesel treatment (only brand ive found which made a notable difference)
failing that white smoke indicates head gasket,
another thing that made one of our 200's slow was a seized turbo regulator, easy to cure using adjustable spanner and some lube, gentally ease back and forth
failing that check your breathers

failing all of that go to the pub  :grin:

It's fixed.

Saturday morning, armed with a box of copper washers and a roll of fuel pipe I systematically began changing all the fuel lines. As it turned out the last one (the one from the tank to the lift pump) was the culprit. Presumably it was within the union on the tank as the lift pump end has been on and off numerous times.

Anyway, its now got a new cambelt, tensioners, lift pump, fuel lines and a replaced 300tdi FIP and I can move onto the vague steering and P-poor braking performance. Ho hum...


Cheers everyone!  :wink:

Saffy:
letting in air or crush restriction ?

bigfatsi:
Who knows?! Can't find anything wrong with the original pipe, but replacing it has fixed so it must be the pipe. QED  :shocked:

Saffy:
I had a few teething problems with a twin tank svo setup with heat exchanger. After x number of miles the heat of the fuel would soften the fuel pipes and the type of joint unions used would then crush the soft pipes closed.

 I also had problems when running purely on diesel in both tanks on long trips, after xxx miles and hours of driving the flat plate water heated heat exchanger that was still inline would have heated the diesel up quite hot, including what was circulating back to the tank. The engine would lose power. I can now switch the HE in and out of the circuit, or rather turn off it's hot water supply.
