What It Helps Address

  • Oil leakage past worn valve stem seals
  • Blue exhaust smoke caused by oil entering the combustion chamber
  • Excessive oil consumption from deteriorated stem sealing
  • Valve guide sealing issues during cylinder head service
  • Loss of consistent exhaust-side sealing on aging Honda and Acura engines

Installation Notes

Verify valve stem diameter and seal dimensions before installation. Clean the valve guide area thoroughly and inspect the valve stems for wear, scoring, or carbon buildup. Use proper engine service procedures during cylinder head work to avoid damaging the seal lip or sealing surface. Confirm exhaust-side placement for the listed applications before assembly.

Quality Assurance

Mahle gaskets and sealing components are used by OEMs and technicians worldwide, and this SS45678 seal set follows that OE-focused approach to engine sealing performance.
