Again...the conditions have changed since the sea trail and when the problem first appeared. The owner changed the oil on both engines. Like 99.9% of us he did not measure how much oil he took out only how much he put in (8 quarts). If it is an oil capacity issue and both pickups were the same.....it would now appear on both engines. If the pickups are different it may happen on only one engine. I'll bet the previous owner knows what is going on.
