how loose should push rods be?
the jeep just started making a terrible engine noise (or it just got bad enough to hear with the top off) sounds like the valves, so i check the timing around 8* so that is ok. took the valve cover off and all the bolts are tight, but the rockers and push rods are loose and have some play in them. they weren't all loose b/c i assume those were the ones that were compressing a valve, but more than half were loose. they shouldn't ever get so loose that they have play in them should they? i had a problem with one lifter last fall, the 'ball' that sits on the end slipped down inside and made it loose, but i replaced it and haven't had trouble since. but now it seems that they are all loose. i took one out and looked at it and it looked fine. any ideas here? it is getting really bad. also it has about 15k on it since it was completely rebuilt.
