Not 100%sure but I think the only difference between the territory and LR eng is the LR has a deeper sump .
Just as a side note did you have the timing belt changed out recently ,ie the 7 year service . Also if you have had all the services done and all other LR stuff complied with then contact LR AU as this is world wide problem for ealier models of TD6 engines where the oil pump cover to which the idler att to breaks off , and press the issue for compensation even if out of warranty ! worth a shot .
