420's bad plugs
has anyone had any problems with the porcelain breaking off the spark plugs. I have discovered after 15,000 miles this has happened. As a result I lost compression in two cylingers and need to do a valve job. What's the chances my cylinders are damaged because of this? It will be the end of a fabulous 420sel if that is the case.......Any feedback will be greatly welcomed....
