Its real easy, take pictures before you start if you are unsure of how it should look when you put it back together. You will not have to reset the valves putting it back together. Loosen the top bolts on the shafts and carefull lift off the back or front section of the shaft. Make sure that when you remove the rocker arm shafts the push rods don't move from on top of the lifters, you can't see them. Replace the oil tube and put it back together. Good luck.
