It time for a new Valve cover gasket, plug tube seals, plug wires and Ignition coil. Valve cover gasket has been leaking for a while, and today I noticed there the tube seals were bad while I was working on something else. Also had the wires undone, and they are all corroded inside, as well s the prongs on the ignition coil. The #1 by far being the worse. I couldn't even see any bare metal. Car has 91k on it so i figure it's prolly time. I may try ans just clean up the ignition coil prongs but definitely time for the other 3. I was shaking and knocking dust out of both ends of the plug wires
