Hello everyone. I'm new here and I need help. I have a 1998 Buick Regal GS and I just bought a set of new valve cover gaskets and grommets so that I can change out the old ones. I was wondering if anyone can tell me if I NEED to remove the passenger side engine mount to change the front valve cover or if I can manage without doing so. If I do need to remove the engine mount, can anyone explain the process to do it so I don't have to figure it out the hard way? Also, what do I NEED to remove to replace the rear valve cover. Any info would be appreciated. Thanks.
