How is the oil pump accessed and serviced within the timing chain cover on Nissan Altima?

The oil pump is located inside the timing chain cover and is driven by the crankshaft, requiring the removal of the timing chain cover for access. Begin by removing the bolts or screws that secure the oil pump cover to the oil pump body, then disassemble the inner and outer rotors, taking care to avoid any nicks or damage, as these can affect oil pressure and necessitate replacement of the entire pump and timing chain cover assembly. Clean all components, including the timing chain cover and engine block gasket surfaces, with solvent, and inspect for excessive wear or damage. Disassemble the relief valve by removing the cap, washer, spring, and regulator valve, checking the sliding surface and valve spring for damage; if either is damaged, replace them as a set. If no damage is found, reassemble the relief valve parts with clean engine oil and reinstall it in the oil pump cover. Check the oil pump component clearance with a feeler gauge and compare the results; if any specifications are exceeded, replace both the timing chain cover and the oil pump components. Assemble the oil pump components, ensuring the punch marks on each rotor face away from the timing chain cover and toward the engine, then pour clean engine oil into the pump cavity and around the rotors before installing the cover and tightening the fasteners to the specified torque. Install the timing chain cover with a bead of RTV sealant on the cover-to-block surface, aligning the flats on the inner oil pump rotor with the crankshaft during installation. Next, install the oil pan, a new oil filter, and add engine oil to the crankcase. Start the engine to check for oil pressure and leaks, perform any necessary re-learn procedures, and recheck the engine oil level.
