July 12, 20169 yr Oil feed port for the rocker shaft is plugged up with some kind of crud. Seems more common for it to happen on the drivers side. Find out which side is tapping the loudest with a stethoscope or long handle screwdriver. Pull the valve cover, rotate the crank so all the valves on that side are closed, then pop the rocker shaft assembly off by removing the eight 10mm bolts. Remove the end cap with the oil feed port, then slide each rocker off and lay them out in order. Make sure they do not get mixed up, they have to go back on in the same order. Blow the end cap and rocker shaft out with air and cleaner. Make sure the cleaner flows through each of the feed holes in the rocker shaft. Oil it up, put it back together and back in the car. If you want you can remove the lifters from each rocker arm and prime them with oil before putting them back in. I usually don't because if you have one that's sticking it can hold the valve open and cause the engine to run really rough. I usually just let the oil pump fill them up after its back together.

Thanks for taking the time to explain that to me. i will read it several times, i also will look for video of the job. i have the hyanes book does it say anything about the procedure ? thanks
July 15, 20169 yr It might say in the cylinder head disassembly section. It's pretty straight forward. Just don't get the rocker arms out of order.
July 15, 20169 yr it'll all make sense when you go in there, it's rather simple there's really only two main steps to his detailed response: 1. pull valve cover 2. remove rocker assembly
