Is it possible to hear valve clatter from the exhaust. Just happen to be
standing behind my Jeep while it was idling in the garage and I could hear
what sounded like valve clatter or I guess you could say a loud taping.
Running '89 Wrangler 6 cylinder with Hanson exhaust and A brand new
engine....overhauled.

If the exhaust is new, look for a bolt or hanger that has come loose or a
clearance issue with the engine running. Sometimes with the engine running
it will displace the exhaust just enough so it contacts something else.

You may want to check the catalytic converter, if you have one. Mine made
quite a rattle when the catalyst broke apart. It also partially clogged the
exhaust outlet at times, causing a discernable power loss and an odd exhaust
note.
