The oil leak may be from overfilling the engine oil. Lehmans don’t like being overfilled. You need to drain all the oil and fill the engine with exactly how many quarts is specified and then mark the dipstick at full. The dipsticks have been known to be wrong according to Bob Smith, he helped design the marinizing of the engines. This is a known issue. I would put some oil absorbent pads under the engine and see where the oil is dripping from. That will give you an idea where the leak is if it isn’t a case of overfilled oil. Then call Brian, Bob’s son, at American Diesel. He is the Lehman guru. 804-435-3107.
