My sisters car has no compression on cylinder 1 and others 150 ish. Investigation found #1 intake rocker is not lined up to the cam lobe meaning sitting half off. Multi air box looks good and moving free but need to know what could cause this and if I need to remove the head and check the intake valves on that cylinder? Need a little guidance since this the first multi air box I have worked on.
