That said it is advised that one changes the oil pump when one is re-constructing the engine, or if it is high mileage or questionable at best. First, disconnect the oil pan, and then working under the car provide support to the oil pump while disconnecting the pump-to-rear main bearing cap bolt. When the level is lowered, remove the pump and also the pump driveshaft. Whenever there may be a new installation of an oil pump, it is recommended that effort is made to align the pump driveshaft to the shaft of the pump. Position the pump on the engine in such a manner that the hex of the driveshaft in the upper end will fit the lower end of the distributor or the camshaft position sensor shaft as proper mating is necessary for the efficiency of the oil pump. Then, screw in the mounting bolt and make sure that the tightening torque is according to the standard. Last but not the least, reinstall the oil pan and add oil doing the reverse of the removal process.

The remainder of reassembly is the reverse of the removal procedure; refer to the relevant text for details where required.

Securely block the rear wheels so the vehicle won't roll, then jack up the front and place it securely on jackstands. DO NOT get under a vehicle that's supported only by a jack!

Install the oil pump chain tensioner to the cylinder block, ensuring the spring is located correctly, and tighten the retaining bolt to its specified torque setting.

Remove the oil pump bolts and take the pump off the engine (Remove the two oil pump bolts).

Install the oil pan and add oil.

Clean the exterior of the oil pump and the mating surface on the cylinder block. Make sure the passage at the back of the oil pump bore in the cylinder block is clean and unobstructed.

Note the different shapes of the ends of the intermediate drive shaft and the location of the retainer ring on the shaft.

Install the oil pump on the block. Install the oil pump bolts and tighten them to the torque.

Remove the oil pan. Then, remove the oil pump and pick-up screen mounting bolts and separate the pump from the engine block.

Remove the two mounting bolts for the chain guide and then remove the guide. The tensioner is secured by one mounting bolt while the guide is held by two.

The intermediate drive shaft should be inserted into the engine, pointed end first, until it engages the oil pump drive. Ensure the travel limit clip is in place and closer to the camshaft position sensor end. It fits tightly on a non-machined section of the driveshaft.

With the engine removed, remove the timing chain.
