[QUOTE="snowflake, post: 204433, member: 152"] I shim towards the biggest end of the spec, although you are correct in that the tight end of the spec is still in spec, you do have a valve that is out of spec so you may as well shim them all. My rule of thumb is that the valves get replaced after 3 shim jobs OR they tightened up really quick (within 5 hours of the last shim job) [/QUOTE]
