How to install and check the oil pump assembly in V6 engine on 1986 Chevrolet Caprice?

Lubricate the pressure relief valve and spring, then install them in the bore of the oil pump case, followed by the cap and gasket, ensuring they are torque-tightened to specifications. Insert the oil pump gear and shaft into the oil pump body section of the timing chain cover to check the gear end clearance and side clearance; place a straightedge over the gears to measure the clearance between it and the gasket surface, which should be 0.002 to 0.006 in. If it is less than 0.002, measure the gears and pocket to identify the out-of-specification component. Check the oil pump clearance, which should be 0.0025 to 0.0050 in.; if it exceeds 0.0050, measure the gears and pocket to find the issue. Use a straightedge across the oil pump cover face to check for flatness, inserting a feeler gauge between the straightedge and the pump cover, and replace the cover if the clearance is 0.001 in or more. If all clearances are satisfactory, remove the gears and pack the pocket with petroleum jelly, avoiding chassis lube. Re-install the gears, ensuring petroleum jelly fills every cavity of the gear pocket and between the teeth, as the pump may not prime if the pocket is not adequately packed. Install the pump cover assembly screws, tightening them alternately and evenly to the specified torque. Finally, install the oil filter and check the oil level with the dipstick, monitoring the oil pressure gauge or warning light during initial start-up and driving; if a lack of oil pressure is indicated, shut off the engine and inspect all work.
