My 2003 Highlander limited 6-cyl. 4WD vehicle has a loud audible clicking noise (sounds like valve lifters ticking) eminating from the engine since I purchased the vehicle new from page Toyota in Jan '2003. The clicking noise is only present when the engine is running. The clicking noise is always audible but the volume decreases as the vehicle reaches normal operating temperature.the clicking noise is very loud when the vehicle is cold. The clicking noise frequency increases with increasing engine RPM and decreases with decreasing engine RPM. The Toyota red holman customer service representative stated that the clicking noise is normal and can not be reduced or eliminated.
