At 80,000 miles we had the water pump replaced on our 2000 Discovery Series II. After picking it up we found that we can only drive about 17 miles (time for the engine to really warm up) and when the engine RPMs drop below 1,000 the low oil pressure light illuminates. The dealer's answer is to replace the engine, which was the same suggestion that they had for the failed water pump. Engine has never over heated or exhited any signs of engine wear, other than this oil presure problem which occured after they replaced the water pump. Dealer did change our oil from synthetic to petroleum based, but I had the engine flushed and changed the oil back to synthetic after the first week, hoping that the issue was one of a clogged sump. Now it's sitting in the drive while I figure out what to do next. Any helpful suggestions on causes and cures? My immediate reaction is to take it to another shop and have the oil pump and pressure transducer replaced.
