Any chance the manuals explain how to adjust the valves. Engine is standard version and engine noise seems to be increasing. Owners manual says to adjust at 60,00 miles and I have about 40,000. Does it require any valve cover gaskets.Thanks

Not a valve job. Owners manual says to adjust valves at 60,000. I have about 40,000 and am starting to hear what I believe is valve noise. Would like proper procedure for adjusting valves.Thanks

has anyone set the valves on their Vibe and can provide proper instructions
