So I went yesterday to the dealer to ask about a valve adjustment and they qouted me like $165. The mechanic i talked to said that he wouldn't adjust them if the camshaft was worn because there would be no point. In that case he would charge me for an inspection and the valve cover gasket. What should i do? I dont feel experienced enough to do this job by myself and i dont really trust anyone else besides the dealer where i live. My car now has over 180,000. Should i just take it to the dealer to see what they do with it? Is there anything else i should ask them to do while they are doing that?
