i ran 75 psi of oil at idle and 120 psi at wot so it would puke oil out of the breathers all over the boat this cured the problem when you come down from wot it sucks the oil back into the block works great .the oil coming out of the breathers wasnt becouse the motor was loose it was tight as hell i had a moroso vac pump on it to make shure it was just to much oil flying around
