What makes the rattle go away on a Jeep Liberty?
I can make it go away by revving the engine several times up to 2500 – 3000 RPM’s; seems like the increased oil flow from higher speeds temporarily stops the rattle/knock. Are there oil galleys in the front top of the engine that get clogged? Is it coincidental that revving the engine makes the rattle disappear?
