Disassembly & Inspection

Remove rear cover. Note direction of gear installation. Mark direction of gear installation for reassembly reference.
On 1.5L models, check outer gear-to-cover and outer gear tooth-to-crescent clearance. Check inner gear-to-crescent clearance. Place straightedge across front cover housing and measure gear end play clearance between each gear and straightedge.
On 1.6L models, check clearance between tip of gear teeth and front cover. Place straightedge across front cover housing and measure gear end play clearance between each gear and straightedge.
On all models, check pressure relief valve for freedom of movement in bore and relief spring tension and free length. Replace components if not within specification. See OIL PUMP SPECIFICATIONS table.
