Bump it up again in an hour or so....there are A LOT more knowledgeable people than I on this Forum. They can tell you how much, which wrench, and the fastest way to get it all done.
Heard good things about Por 15 but have never needed it yet. Plugs ---- there is a thread, but be sure to regap, they usually are not set correctly. Not that most people on here don't see eye to eye, one of the most knowledgeable is Jerry ...he may chime in later, still early in CA.
