Pushrod/Rocker Arm Q's

[88WhiteGTConv]

Ok, so im troubleshooting my cars valve train noise. I pulled the valve covers off and found that my number 4 pushrod was a tad loose? Is there supposed to be any freeplay in the pushrod when the valve is fully closed? I can make the pushrod click when i rattle it up and down. Does that sound like misadujusted valves from the shop that did my headgasket? My car has been running like crap since i got it back, long story on this one.....

sounds like you need to do a valve adjustment real quick and see what happens....it may be possible that you have a bad lifter too......start with the valve adjustment........hotwheels of turborides.com

Well i gotta pull the lower intake off anyways, i think i have a collapsed lifter on my number 6 cylinder. Got new lifters to be put in, so ill check all the pushrods for trueness. Also can someone explain the process of adjusting the valves and where to get shims if i need them?

You can order a shim kit from JEGS, SUMMIT or if your lucky the local Ford Dealer. I'm assuming you have ped mount rockers since you are asking about shims.

Here's how you adjust them and some good reading...
