NOTE: Second Design Oil Pump and Rear Timing Belt Cover Information Starting with engine unit number 08191279, a second design oil pump housing and rear timing belt cover were introduced into MY97 Catera production. The second design rear timing belt cover features an additional hole that allows access to one of the oil pump bolts located behind the cover. Since it is necessary to re-torque all of the oil pump bolts after the timing belt idler pulley installation, the access hole was added to the cover to make the re-torque procedure easier. The second design oil pump has an extended boss to shield the access hole in the rear timing belt cover from road and other debris. Both first and second design pumps use the same gaskets. Second design pumps can be installed on first design engines, however, it requires the use of the second design rear timing belt cover and a longer (M6 x 25 mm) oil pump bolt in the number six position.
