    Kind of hard to adjust valves on a DOHC engine.

    Aren't they hydraulic lifters on these motors? Hydro lifters 99 times out of 100 don't need to be adjusted.

    There is no valve adjustment.....if your valve train is noisy there are deeper issues. Make sure it is not the injectors your hearing (DI injectors are very loud).

    How many miles on the motor? Ever run oil low? have you always run full synthetic? (timing chain issues).

    Its the 3.6l 94k an as far as I know never ran low an full synthetic but iv only had the car since 87k

    ----------

    It sounds like my lifters or retainers are loose or something I can hear it really good from the drivers side of the motor

    ----------

    I dont know what really it is tho my honda sounded like that an I had them adjusted an the sound went away so thats what I was using for a reference

    You may have a worn follower. Remove the valve cover and with the cam lobe facing up feel each for excess play. Your also due for a timing chain replacement to avoid jumped timing.

    Due for a timing chain replacement? Isn't the chain supposed to be fine for the life of the motor? Unless it develops slack or snaps.
