SERVICE DATA AND SPECIFICATIONS (SDS) — General Specifications; Inspection and Adjustment (Supplement-V)
EM-5046spec tableValve seat angle row uses 'Intake' and 'Exhaust' columns even though both values are 45°; valve stem diameter is the same I/E (6.980-6.995 mm). VJZ is a 1.5L IDI diesel: 1527 cm³, bore 77 × stroke 82 mm, CR 23, SOHC, firing order 1-3-4-2. Valve clearance values match what was documented procedurally on EM-5028 (cold check).
