So I noticed something while adjusting the valves on my '08 Norge .. Do the marks on this valve cover indicate a bad spark wire or is it just crappy paint.. The little black spots are actually pitted in to the base metal. The other cover looks fine..


The spark plugs look pretty good I think for 10K miles so I didn't change them. These have been great so I didn't want to change brands and the parts store I stopped at didn't have the Bosch Platinum Fusion plugs. These look like they could be lifetime plugs.
