Just asking what to expect if I buy a Disco 1998 with 113K miles. Some tell me most headgaskets need to be replaced at 120K. Since I don't know the history of the Disco should I just drive it or should I replace them.

Anythoughts would be appreciated?

Cheers

Would you not best just do the job right and throw in a new clutch, gearbox, and transfer box too? And none of those "reconditioned" things either, Get new ones from the official LandRover dealer. No point in scrimping.

Have a few 300 Tdi's in the family circle - one has 146,000 mls and head has never been touched and given no problem . Had to replace the head on one with 138000 mls but this was because of overheating - a 'weakness' of the 300 Tdi is the water pump sits high on the engine and a small drop in coolant level can mean no coolant being pumped and a cooked engine .
I have read on another forum about using a Range Rover cap for the expansion tank and this can be used to trigger a buzzer or light should the level drop .This would I feel be of great benefit to the 300 Tdi and hope to rig up one or two of them .
IMHO changing the head gasket just because of the mileage would be unnecessary - if the coolant level is maintained the head will probably never give any trouble . You could change it and the following week a leaky hose could wreck the head .

Do you mean this one DifflockCoolant level sensor ... UPDATE
 
Yes , the one on the Difflock forum is what I had in mind . I have got the RR cap from the main dealer and am sending for the unit which activates the buzzer/light . Having , as I said , replaced the head on my sister's Tdi I have told her to keep a very close check on the coolant level until I get the unit in place .
Many people get used to the coolant level dropping , sometimes quite a bit , without causing any problems . But not so with the Tdi - regular checks and curing even very minor leaks of coolant is very important .
