I know the answer is somewhere in the threads , but im no good at finding things in the search area, so heres the problem, i have a bad tapping coming from 2 or more rockers , ive tried to halve ass adjust them but oil gets every where,tonight i took each rocker off 1 by 1 to visually inspect them,even though i really dont know a bad from a good one , but they did not look too worn, and the pushrods were not bent, i did find some thing that disturbedme though, 1 of the valves rattled a slight bit when i pushed it from side to side , im no expert but this does not seem right,but im not getting oil by the guides,i guess my question for yall is how do i know what component is bad? , how do i tell if a lifter is sticking or not? and does any body have any secrets on how to adjust valves without getting oil every where? i tried the clips ,did not work to well,oh the engine is stock 350, flat top pistons, 202 , 64cc heads, no fancy rollers or nothing ,just stock stuff,any tips would help tremendously, thanks
