People Hi from Greece,
my 1994 ex Greek Team Camel Trophy Discovery 200Tdi had developed a clickin g noise for about four months now after running it with WVO (waste vegetabl e oil) for the previous 2 months. Apart from the clicking noise it also started smoking heavily from the exha ust especially when the engine was cold. White to whitish-grey smoke which smelled of diesel not oil.
After reading a lot on the various fora/forums I changed the timing of the pump (the BOSCH VE one) and the clicking noise has almost gone along with t he heavy whitish smoke from the exhaust.
But then, after about 500 Kms both symptoms reappeared and the clicking no ise became stronger along with heavier whitish smoking from the exhaust.
Today while driving the noise became much stronger and a lot different, the smoke became black when trying to accelerate and the engine lost power. B ut the most alarming thing is that it sounded like trying to explode.
I opened the bonnet and realized that the rubber hose connecting the interc ooler to the intake manifold what pulsating and that there was air trying t o come OUT of the air filter housing (remember this is a camel trophy Disco very and it was a mantec snorkel fitted to the air filter housing).
When we finally managed to drive back home I removed the rubber hose from t he intake manifold and the car has started sounding as if I have removed th e exhaust while on the same time there was air coming OUT of the intake man ifold (which should normally suck air inside towards the engine).
What what do you thing about it?
I believe that there must be something very wrong with one, hopefully not m ore than one, exhaust valves or pushrods or with the timing of the engine. Could it be a problem with the timing belt "jumping" more than one tooth?
Could it be a problem with the fuel pump because of the use of WVO ?
your comments and ideas are greatly appreciated.
Since on every previous occasion the Greek mechanics managed to create more problems then the ones they have tried to solve I have decided to try and fix this problem myself with your assistance, knowledge and experience.
If any of you has had this problem in the past, based on the described symp toms, I would be grateful if you could share your knowledge and experience.
I do have the workshop manual, full set of tools including torque wrench, a complete upper engine gasket and bolts kit, a full timing belt kit and a s pare cylinder head.
thanks in advance for your kind assistance
Take care Pantelis Giamarellos
