Okay, here is the deal. Our "rebuilt" 258 seems to have a problem. One of the rocker arms is really loose. It rattles really bad and I'm not sure how to fix it. The nut on the top isn't loose, and the pushrods are all the same length, so I don't know what to do. The rocker is on the second intake valve from the firewall. When the engine turns and the pushrod raises, the rocker becomes tight kind of like it should, but when it goes back down it is really really loose. This engine has probably only been running for about 15 minutes since the rebuild, so I'm hoping that a lifter is stuck and can easily be freed. Can anyone give me some advice? The jeep actually sounds pretty smooth at idle, but the engine shakes quite a bit. Is that normal, or are these two problems related?
Thanks
Zac
