GSC P-D 2023+ Nissan 400Z VR30DDTT Valve Stem Seal - Set of 24

If you're rebuilding the top end of your 2023 or newer Nissan 400Z with the VR30DDTT engine, you'll need a fresh set of valve stem seals. These seals are crucial for preventing oil from leaking past the valve guides and into the combustion chamber, which can cause blue smoke on startup and increased oil consumption.

This set from GSC Power Division includes 24 seals, enough for all the valves on your V6 engine. GSC Power Division is known for making well-built internal engine components, and these seals are designed to fit right and do the job of keeping oil where it belongs. Replacing these is a common step when you're doing a valve job, replacing valve springs, or swapping camshafts.
