Land Cruiser Cylinder Head Gasket Mark 3— 1HZ, 1HD-T 4.2L Diesel | HZJ70/76/78/80/105 Series (1990–2024)

Cylinder Head Gasket — Grade 3 for Toyota Land Cruiser and Land Cruiser Prado (HZJ, HDJ-series), powered by the 1HZ or 1HD-T — 4.2L I6 Diesel.

This is the Grade 3 gasket — a slightly thinner Toyota factory specification within this engine family, measuring 1.25 – 1.35 mm compressed thickness. Piston protrusion must be measured at each cylinder before installation to confirm adequate clearance and to verify this grade is correct for your application.

Gasket Selection by Piston Protrusion

1HZ engine: Grade 3 — use for piston protrusions between 0.456 – 0.555 mm

1HZ-T / 1HD-T engines: Grade 3 — use for piston protrusions between 0.526 – 0.625 mm

If a Thicker Gasket Is Required

• If Grade 3 is too thin for your measured protrusion, see our Grade 5 listing (11115-17040-05).

Complete the Job Right

A proper head gasket replacement also requires new head bolts and a full upper-end gasket set (VRS or complete engine set). See related products below.
