I think I would take the valve cover off and look at the 4 cylinder rocker arms before the motor is dropped. Maybe it's just a broke or loose rocker. If the intake valve isn't opening it won't have any compression probably. If it's a valve seat it should have a lot of air coming out the intake or exhaust while cranking. You could just put a air hose in the spark plug hole using the compression checker hose and listen for where the air is coming out to see whats what. If the seat is loose it should be holding the valve lower under the rocker arm and the pushrod should be loose or out from under the arm maybe?

If the valve was stuck closed, it would make compression. Zach |
