I was told by a Duratec engineer that the best thing that we could do for cheap is run a half quart over the full line- that should help-
FYI the oil pan in the duratecs is about 3/4 quart too small for the motor because so much oil stays up in the cams area- gets too much air in it and then when you need it its still up there trying to get back to the oil pickup -
so run a 1/2 quart high and it should be ok.
