Is your RB25DET NEO puffing blue smoke on startup or during high-vacuum deceleration? Don't settle for aftermarket rubber that can harden and crack after a few heat cycles. Restore your engine's oil control and reliability with these Genuine Nissan OEM Valve Stem Seals.
Designed specifically for the solid-lifter NEO cylinder head, these seals provide the precise tension required to keep oil in the head and out of your combustion chamber. Whether you are performing a mild refresh or a full-scale rebuild, using factory seals ensures you won't be pulling the cams again to fix a leak.
Why Genuine Nissan Rubber?
Thermal Resilience: Unlike cheaper aftermarket alternatives, Genuine Nissan rubber is formulated to withstand the intense, fluctuating temperatures of a turbocharged RB cylinder head without hardening.
Precision Fitment: Engineered specifically for the RB25DET NEO valve guide dimensions to ensure a perfect, airtight seal every time.
Oil Consumption Solution: Eliminates the "blue smoke" symptom caused by worn, brittle, or ill-fitting valve seals, restoring your engine's internal efficiency.
