  Q: How is the oil pump disassembled and reassembled within the timing chain cover on Nissan Rogue?

  A: The oil pump is located inside the timing chain cover and is driven by the crankshaft. Begin by removing the timing chain cover, followed by the oil pump cover-to-oil pump body retaining fasteners, then disassemble the inner and outer rotors, taking care with these components as their close tolerances are critical for maintaining correct oil pressure; any nicks or damage will necessitate replacing the complete 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, then check the oil pressure regulator valve sliding surface and valve spring; if either is damaged, they must be replaced as a set. If no damage is found, reassemble the relief valve parts, coating them with clean engine oil, and reinstall in the oil pump cover. Check the oil pump component clearance with a feeler gauge and compare the results; if any measurements are out of specification, 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 to the pump body and tightening the fasteners to the specified torque. Install the timing chain cover using 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. Proceed to install the Cylinder Head and other components, followed by the Oil Pan, a new oil filter, and adding engine oil to the crankcase. Finally, start the engine and check for oil pressure and leaks, then recheck the engine oil level.
