Once my cars engine is no longer warm it makes a loud metallic knocking sound sometimes the engine shakes as well it's most noticeable when it has been sitting all night. My check engine light was on for a day but then went off I took it to get the codes ran some errors with the cam shaft registered. I have replaced the cam shaft sensor the problem seemed to get better but the problem is still present I'm thinking it's the cam syncronizer but I want a second opinion before I replace it
