Oil Pump: Removal
NOTE:
Early build engines are equipped with an oil pump drive chain guide. Late build engines do not have an oil pump drive chain guide. Also, late build engines use an updated design for the oil pump drive chain and tensioner. Therefore, the oil pump drive components are not interchangeable between early build and late build engines.
