Intake Leaking Oil

No what it means is neither side will seal properly if the bolts are tightened in a perfectly equal fashion and since thats not going to happen you are going to get a bad bank depending on which side gets pulled first the intake must have room to suck down without bottoming on the rail but as Kimmer said you are probably going to have to lift the intake to get the bolts in if you clearance the ends to allow this to happen so it sounds like you need a new intake to me .
