Product Details

The MAHLE SS45779 Engine Valve Stem Oil Seal Set is a professional-grade replacement seal kit from MAHLE Original, also marketed under the Victor Reinz brand. Engineered to meet or exceed original equipment specifications, this seal set restores proper valve train lubrication control and helps eliminate oil burning, blue smoke, and excessive oil consumption caused by worn or degraded valve stem seals.

Why Valve Stem Seals Matter:

Valve stem seals regulate the amount of oil that lubricates the valve stem as it slides within the valve guide. Too little lubrication accelerates stem and guide wear, while too much oil leads to increased oil consumption, carbon buildup on valve seats, premature valve failure, reduced engine performance, and emissions failures. Replacing worn seals with a quality set like the SS45779 restores the correct oil film and protects engine longevity.

Key Features:

  • Meets or exceeds original equipment (OE) specifications for fit, form, and function
  • Manufactured by MAHLE Original / Victor Reinz — a trusted OEM supplier to major automakers worldwide
  • Premium materials engineered for superior sealing performance and extended service life
  • Complete set packaged in a shrink-wrapped tray for part verification before opening
  • Prevents oil from entering the combustion chamber, reducing emissions and maintaining fuel efficiency

Cross-Reference Part Numbers:

  • MAHLE: SS45779, B45779
  • Victor Reinz: B45779
  • General Motors OEM: 10147882
  • Fel-Pro: SS 72877

The MAHLE SS45779 valve stem oil seal set is trusted by professional technicians and OEM manufacturers alike, making it a reliable choice for engine rebuilds and valve train service.
