Victor Reinz 703130600 — Valve stem seal

Victor Reinz 703130600 valve stem seal — a seal for engine valve guides: it keeps oil from entering the combustion chamber and reduces oil consumption due to burn-off. The part is supplied under the Victor Reinz brand, has 133 analogs and is used in various VAG Group engines and beyond. The size is indicated in the name — 6x8.8\12.2x9.7, so before purchasing, verify it against the guide and valve stem parameters.

The seal is found on Audi A2 (8Z0), A3 (8L1) and A4 (8D2, B5), as well as on Alfa Romeo MiTo 1.3 MultiJet of various model years — a total of 500 fitment rows in the catalog. When selecting, rely not only on the model and year, but also on the specific engine: different engines may have different guides and seal dimensions. Verify the size and part number against the manufacturer's data to avoid installing an incompatible part.

Among the analogs there are original numbers SKODA 6 42 533, PORSCHE 955 105 675 00, JEEP 68066168aa, BMW 1134 2 245 151, ALFA ROMEO 4647334 and SEAT 7700109840 — they should be cross-checked against the catalog for your engine. Check compatibility by VIN or engine number, as well as by seal size, not just by model name. Replacing the seals is usually required when blue smoke appears from the exhaust, oil consumption increases and oil deposits form on the valves — based on engine diagnostics.
