just fitted the engine from my dads old discovery in my 110. got the engine in and all coupled up. when i started it up the oil light stayed on. swapped the pressure switches over and still on so took off an oil cooler pipe and it was empty. when i changed the engine i had the filter off and it has filled again. i let it tick over for about 5 or 10 minutes but still no pressure. any ideas?
