Thickness Selection: The 4JJ1 cylinder head gasket is available in three thickness grades — 1.05 mm (one notch), 1.10 mm (two notch), or 1.15 mm (three notch). Selection is determined by measuring piston protrusion above the block deck. Always match the notch count on your original gasket-10.
Surface Preparation: Both cylinder head and block surfaces must be clean and flat. Remove old gasket residue with a plastic scraper. Do not use abrasive discs. Check cylinder head flatness per the Isuzu service manual.
Torque Specification: Tighten cylinder head bolts in the specified sequence using multiple progressive stages. Always replace head bolts with new torque-to-yield units.
No Additional Sealant: Install the gasket dry on clean surfaces. MLS gaskets require no sealant. Do not apply RTV or any gasket sealant to the gasket itself.
