Diagram Ref No 20

Camshaft and balance shaft oil seals are exposed to constant rotation, engine heat, and oil pressure throughout their service life. Over time, the sealing lip can harden, wear, or crack, allowing oil to leak from the engine. Oil leaks not only create a dirty engine bay but can also contaminate timing belts, auxiliary drive belts, and surrounding components, potentially leading to more costly repairs. Replacing worn seals during engine servicing or timing belt replacement helps maintain proper lubrication and engine reliability. This OE Match seal is ideal for routine maintenance, engine repairs, and Porsche restoration projects.  

What This Product Does:
  • Prevents engine oil from leaking around the camshaft or balance shaft.
  • Maintains correct engine oil sealing.
  • Protects against the ingress of dirt, moisture, and contaminants.
  • Helps safeguard timing belt and surrounding engine components from oil contamination.
  • Restores the integrity of the engine sealing system.
  • Replaces worn, hardened, or leaking original seals.
  • Provides an OE-style fit and dependable performance.

Symptoms Of Wear Or Failure:
  • Engine oil leaking from the front of the engine.
  • Oil contamination on the timing belt or pulleys.
  • Oil residue around the camshaft or balance shaft housing.
  • Hardened, cracked, or damaged seal.
  • Oil spots beneath the vehicle after parking.
  • Increased engine oil consumption due to leakage.
  • Evidence of oil around the timing covers.
  • Age-related deterioration of the original seal.

Why Replacement Matters:

  • The camshaft and balance shaft seals play a vital role in maintaining engine oil containment while preventing contaminants from entering the engine. A worn or leaking seal can lead to oil loss, contamination of the timing belt, reduced engine reliability, and, if left unattended, expensive engine damage.
  • Replacing the camshaft or balance shaft seal restores effective oil sealing, protects critical engine components, and helps ensure long-term engine reliability. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match seal provides the correct fit, dependable performance, and long-lasting durability, making it an excellent choice for Porsche maintenance, repairs, and restoration projects.
