Product Description
The ELRING Valve Stem Seal Set (702.706) is a critical engine internal component designed to prevent engine oil from leaking past the valve guides and into the combustion chamber. As a world-renowned manufacturer of sealing technology, ELRING produces these seals using high-grade fluoroelastomers (FPM/FKM) that remain flexible and resilient despite constant exposure to extreme heat, pressure, and chemical degradation from engine oil additives. A failed or hardened valve stem seal is the most common cause of "blue smoke" emitting from the exhaust during cold starts or after idling, as oil pools in the combustion chamber through gravity.

| Skoda / Seat | Various 8v Petrol engines | 1990s - 2000s |
⚠️ Installation & Technical Warning:
- Professional Precision: Installing valve stem seals requires removing the camshaft and cylinder head (or using a specialized "valve-in-head" spring compressor tool). It is imperative to use a seal installation sleeve (often included or available separately) when sliding the seal over the valve stem groove to ensure the delicate inner sealing lip is not cut by the sharp valve collet grooves.
- Cleaning: Before installation, ensure the valve guide top is clean and free of burrs. A small drop of clean engine oil should be applied to the seal lip to prevent it from dry-running during the first engine rotation.
- Verification: This set contains 8 seals. If your vehicle uses a 16-valve cylinder head, you will require two of these sets or a dedicated 16-valve specific set. Always verify the valve stem diameter (typically 8mm for these classic VAG engines) before beginning the installation.
