Better recheck again-Nowadays we use Type 4 closed ventilation system-did you check on top of the valve cover-sometimes you have to pry it off and end up braking it. and while your on it-check the filter and hoses in the air housing.

Your problem is, its flowing backwards creating the pressure and can blow out oil seals.
