this might help someone in the same situation as i was
my disco td5 1999 blew the engine and i thought o dear or words similar
but when i checked on the net i found that 99 gs td5"s were shearing oil pump bolt ,or falling out all together contacted landrover when i sent my service history they ok"ed new engine and turbo £6000 worth took about 5 months but worth the wait

well done you'll be a giant killer then...

no sold it bought defender
