BMW M3 M5 M6 Valve Guide Oil Seal Set for S65 and S85 Engines — Part No. 11340032548

End start-up smoke, tame oil usage and keep your M Power engine crisp with this factory-original valve guide oil seal set. Built to BMW standards for the 4.0 V8 S65 and 5.0 V10 S85, this OE kit delivers the correct sealing performance the valvetrain needs on E9x M3 and E6x M5 M6 platforms. If you are seeing a blue haze after idle or on overrun, refreshing the stem seals is the smart, long-term fix that protects your catalysts and keeps emissions in check.

We fit this set in-house and customer feedback has been excellent. Results speak for themselves: cleaner cold starts, reduced oil burning and a smoother, cleaner exhaust note. Ideal whenever you are carrying out head work, valve servicing or a top-end refresh.
