GSC Power Division Valve Stem Seal Set (Set of 24) Nissan Z 2023-2026 | 1056

The GSC Power Division Valve Stem Seal Set is a precision-engineered replacement and upgrade solution designed specifically for the 2023+ Nissan 400Z equipped with the twin-turbocharged VR30DDTT engine. Engineered to OEM-equivalent or superior tolerances, these valve stem seals prevent oil from migrating past the valve guides and into the combustion chamber — a critical maintenance and performance upgrade for both stock and modified VR30 builds. Whether you're refreshing a high-mileage engine or building a high-performance street or track setup, this complete 24-piece set ensures every intake and exhaust valve is properly sealed.

Key Features & Benefits

• Complete 24-Piece Set — Covers all intake and exhaust valves in the VR30DDTT engine, eliminating the need to source individual seals and ensuring consistent sealing performance across all cylinders.
• High-Quality Elastomer Construction — Manufactured from premium heat- and chemical-resistant rubber compounds that maintain a reliable seal under the extreme temperature cycles of a turbocharged engine.
• Precision-Machined Tolerances — Engineered to exact dimensional specifications for the VR30DDTT valve guides, ensuring a secure press fit and proper oil control without excessive restriction or leakage.
• Prevents Oil Consumption & Blue Smoke — Worn valve stem seals are a leading cause of oil burning and exhaust smoke; these seals restore proper oil control and protect combustion chamber cleanliness.
• Ideal for Performance & Engine Rebuilds — A must-replace item during any head gasket repair, cylinder head refresh, camshaft upgrade, or full engine rebuild on the 400Z VR30DDTT platform.
