Engine Noise On
Acura 2.5L & 2.7L Engines
AERA Technical Committee has been made aware of an often misdiagnosed engine noise on all Acura, Legend vehicles using both the 2.5L and 2.7L V-6 engines. The sound is described as a howling noise that is generally thought of as a bad timing belt, idler pulley or water pump.
Prior to disassembly for any of the above listed reasons, verify that there is no oil pan damage. Damage to the bottom of the oil pan may have reduced the clearance between the oil pick-up and may cause a howling noise that gets louder as RPM increases. If this is the case, the above mentioned repairs would be unnecessary.
