    Q:
    How to remove and install the Oil Pump assembly in V8 engine on Oldsmobile Cutlass? Posted by Ehsan R.
    A:
    Take off the oil pan and up to 6 bolts that hold the oil pump assembly on the rear main bearing cap and extract the oil pump with its pickup tube and screen in one piece from the block. To install; place the pump assembly and ensure that the slot on the last end of the extension shaft fits into the tang on the lower end of the distributor because the distributor will power the oil pump. Use bolts and torque tighten it to the best of the specification for securing the assembly. Make sure that the oil pump screen sits correctly next to the oil pan rails to fit correctly in position at the oil pan. Lastly, fit the oil pan and check the oil pressure or the lamp during the period that you start the engine for some time.
