Hello, have a 557 big block ford in my jetboat, Im having a problem with large amounts of oil in the bilge of the boat after a long run on the lake.
Heres some details ford motorsport block, crower billet crank and rods, LSM 55 mm roller cam, jesel lifters, kaase worked scj heads, danny b belt drive, tunnel ram with 2 gary williams dominators, compression is about 9 to one. makes 752 hp and about 730 ft lbs torque on the dyno. Motor works fantastic except for this oil leakage problem. Oil does not leak when sitting with motor off. Oil temp is about 230 in pan and 190 going into engine out of the cooler.
The funny thing is motor does not leak oil on dyno, or when we pressurize oil gallies with drill. It has a brand "D" 14 quart pan, with an oslon oil cooler, oil always seems to be coming out the crank area of block {flywheel side}. Im thinking since the ford has such a small main seal that oil from the pan is running up the back and putting a lot of oil around main seal. hence the leaking.
Im thinking I may have to lengthen windage tray to help control oil sloshing up back of the pan when accelerating or ????
Also motor has a kaase oil pump and two valve cover breathers, one on each cover. I am going to a puke tank and a larger hose set up to see if makes any difference when spring time rolls around. Running rotella 15/40 oil.
So, i guess im just looking for thoughts and opinions on this, if any one else has had problems like this. Thanks
