My 87 aq131a/275 runs like champ. It doesnt overheat even on just a hose and its nice and smooth and quiet especially since the fuel water seperator was put on. My only slight concern is a small oil drip toward the front of the motor when its running. Dont know if its from the oil pan gasket or somewhere else. It doesnt seem to be running down the side like from the filter area or anything. Any suggestions on trouble shooting this would be helpful. When I say front of motor thats just where it is gathering under the oil pan and dripping off of it. Thanks
