    I have a head off at a port shop right now getting a valve job done and getting re-surfaced.

    I need some help for when I get it back.

    The motor has no rocker arms or cams in it.

    I am a novice DIY-er (I know how a engine works, but I dont rebuild them often) and i need to know how to asjust the valve lash and the rocker arms when I get the head back.

    The head will be off the vehicle when its getting this maintenece.

    I need pictures, where to put wrenches, what ways to turn them, where to put the feeler guages, etc.

    All info would be greatly appricieated.

    Its covered in a chiltons manual. And you can not adjust the valves/rockers with the head off the motor, well I guess you can but why would you want to?

    You will need:
    • 10mm boxed end wrench
    • flat blade screw driver
    • feeler gauges
    • 19mm socket/ratchet (to turn engine over)

    You will need to set each cylidner at TDC. TDC = top dead center. Start with cylinder 1, of course.

    Please purchase a service manual for you car though, becuase im sure I have left some shit out. However, this is sorta a basic guide, good luck.

    the head is already off the motor anyway, and id prefer to work on it on a table instead of bending over the car the whole time anyway.

    I highly doubt its a good idea to do a valve adjustment when the motor is not together... if someone has a diff. opinion, please let us know.

    you always adjust valves with the motor at normal operating temperature anyway...

    autozone.com, free repair section
    should explain it

    My service manual and c-speedracing says to do it when the engine is cold.

    Yea, its to be done when the engine is cold (as, metal expands as it heats up).

    Its actually quite easy to find TDC with the head off. How about when all the valves are closed? Thats one way to do it. Adjusting the valves off the car is fine.

    What makes it right or wrong? I have adjusted them on the bench so many times that i forget, and have yet to have a come back for any valve noise.

    No i hear you. It is easier doing on the car reason being, if you haven't done enough on the bench, what seems tight isn't and may tap a bit. But you should always pre adjust on the bench to make sure its not to tight or loose from the machine work. But i would advise to do it on the car, however if you have experience, off the car is just as good

    coupla days old...

    thought i would toss this in for novelty. Talked to my buddy from the dealership, too, and he said they won't do a valve adjustment unless the motor is "sat in the shop over night" kinda cold, despite what the service manual says, which is as follows:
