Elring 010300 — Valve stem seals

Elring valve stem seals 010300 (part number 010.300) are sealing elements that fit over the exhaust valve stems and keep oil from entering the combustion chamber. They are made of ACM (polyacrylate rubber), height 9.5 mm, inner diameter 7 mm, outer diameters 12 and 13.5 mm, weight 2 g. The part is designed for exhaust valves of Honda engines and related motors.

The seals are used on Honda Accord CC/CD (1993–1997), CE/CF (1995–1998) and CG/CK (1997–2003) generations, Acura Integra with 1.6 engines, Rover 200 and 200 Coupe, MG ZR and Express, as well as Land Rover Freelander I with the 2.0 Di diesel. When selecting, it is important to note that the part is specifically for exhaust valves, so before ordering verify the valve type and engine by catalog, not just by car model.

When choosing an alternative, focus on the dimensions (7 × 12 × 13.5 mm, height 9.5 mm) and ACM material; among the replacements in the catalog are NOK BV3159H0, BSG BSG30-116-101, Payen PB353 and OEM Honda numbers 12210-PT2-004, 12211-PT2-003, 12211-PH7-004. Compatibility is best checked by VIN or engine number, since different engines could be fitted to the same model. Valve stem seals are replaced when blue smoke appears from the exhaust, oil consumption increases and spark plugs become oil-fouled, usually together with an inspection of the valve assembly.
