Vehicle developed a ticking noise from what seems to be cylinder 6. No issues with idle of drivability. Seems to be rpm dependent but after 2k rpm noise is drowned out. Originally I thought it was an injector since feeling the fuel line on 6 the pulsing was different from the rest. Just replaced #6 injector with a used index9, ticking is still there but pulsing feels the same across all injectors. Has anyone experienced this, need to do a valve cover gasket and would like to be someone prepared if additional items need to be taken care of.
