Hi guys and gals,
Update on the noise.
Tried replacing the injectors with serviceable ones, and changed fuel filter, checked air filter, but still the noise on tickover. Spent two days tracking down an EDC injector, and had all the original injectors tested, ok. Fitted original injectors and the replacement EDC injector. Still no difference, so refitted original EDC injector. Decided to take car through to an independant LR garage.
Driving through town on the way to the garage and lost drive!!! Gear oil leak from torque convertor/gearbox!!!
Got recovered to the garage. Recovery truck lost PTO, so ended up reversing truck into the workshop and raising a car ramp to the required hight and pushing the stricken Discovery onto the ramp.
Initial inspection shows gear oil leak coming from the bellhousing breather. Mechanic also thought that perhaps the front crank drive pulley may be out of alignment (creating the original noise from the engine), as it is, on the way to the garage, the ENGINE CHECK amber light came on for long periods of time.
I must be the unlukiest Land Rover owner around.
Owned four, three requiring major rectification (at major costs) over these past years.
Time to knock it on the head and get a Toyota???
