Toyota Land Cruiser Cylinder Head Gasket — Mark 1 | 1HZ, 1HD-T 4.2L Diesel | HZJ70/76/78/80/105 Series (1990–2024)

Cylinder Head Gasket — Grade 1 (Mark 1) for Toyota Land Cruiser and Land Cruiser Prado (HZJ, HDJ-series) powered by the 1HZ — 4.2L I6 Naturally Aspirated Diesel or 1HD-T — 4.2L I6 Turbocharged Diesel.

This is the Grade 1 gasket — the thinnest version in the series. Piston protrusion must be measured at each cylinder before installation to confirm this grade is correct for your application. When protrusion data is unavailable, use Grade 5 (thickest, most conservative choice).

Gasket Selection by Piston Protrusion

1HZ: Grade 1 — smallest piston protrusion range in the specification

1HZ-T / 1HD-T: Grade 1 — smallest piston protrusion range in the specification

Complete the Job Right
