I started on my project to replace the valve stem seals, but the spark plug tubes are stuck to the valve cover, so there's not enough room to maneuver the cover out.


I've tried sticking a deep 24mm socket into the tubes and trying to hammer the tubes out, but no luck. And there's not enough room for me to get my hand in from the top or side to try and wiggle them out.


Anyone have other tricks to try?
