1984-300SD-5 cylinder Turbo and the oil pressure gauge always reads 3 bars....engine off or running the gauge always shows 3 bars...Disconnect the sending unit and it still shows 3 bars...
Any ideas...thanks...Jim

replace it? the whole thing. find one off ebay as it is very important not to run with no oil pressure.
