We put 8 quarts of mineral engine oil into the the engine, removed the spark plugs and turned the engine over and nothing happened! Turns out the starter selonoid was all corroded and seized up. So we by passed the selonoid and cranked the engine over for 20 seconds but no oil pressure and a small leak on one of the hoses. So we tightened the hose and checked all the other connections then tried turning over the engine again for 20 seconds, after 10 seconds we got oil pressure! We have ordered from AS, a new starter selonoid and a new fuel boost pump.
