Detailed Description

DJ Rock HGS433 is an engine cylinder head gasket set engineered for complete cylinder head service on the Mazda Protege. The set is built around critical sealing points between the cylinder head and engine block, with materials selected for oil, coolant, and combustion sealing performance.

Common Repair Uses

• Oil contamination at the head-to-block sealing surface
• Coolant seepage into the combustion chamber or oil passages
• Top-end reseal during cylinder head removal and inspection

Installation Notes and Tips

Clean and inspect all mating surfaces before assembly. Follow the factory torque sequence and torque specifications for the Mazda Protege engine, and replace torque-to-yield head bolts rather than reusing them. Verify bore size and engine code before installation, and confirm all sealing surfaces are free of warpage, corrosion, and old gasket material. Use HGS433 only on the confirmed 1995-1998 Mazda Protege application listed above.

Quality Assurance

DJ Rock HGS433 is manufactured with non-asbestos materials and built to meet or exceed OEM quality standards. The gasket set uses application-specific sealing materials, including MLS, graphite, composite, rubber, silicone, EPDM, and Viton valve stem seal materials where applicable, to support reliable engine sealing in service.
