Disassembly & Inspection (1.5L)

Remove gear cover. Note and mark direction of installed gear for reassembly reference, using felt pen.
Measure clearance between outer gear and cover. Measure clearance between inner gear tip and outer gear (except Precis). On Precis, measure clearance between crescent and gears.
On all models, place straightedge across front cover housing. Measure gear end play clearance between each gear and straightedge.
Inspect pressure relief valve for freedom of movement in bore. Measure spring tension and free length of relief valve spring. Replace components if not within specifications. See OIL PUMP SPECIFICATIONS table. Inspect oil pan for cracks or damage. Inspect oil screen for clogging.
