I too have a Perkins 4-108 (1985 vintage). Back in 1985 when I first bought the boat, the mechanic told me to fill the oil higher than the dip stick indicated since the motor was mounted in a fore aft angle of maybe 20 %. I have always followed his instructions and the motor has done well over the years. Knock on wood. I'm not sure about the angle of heel and don't usually motor when sailing to windward. The boat is very tender and I do probably see an heeling angle approaching 25 %, but not sure what heeling angle will starve the motor of oil.....Thinking more about it, I would like to know where the oil pickup "tube" is located in the sump. It would seem that if it's aft, then there is no reason the "overfill" the oil??
