Original BMW VANOS Oil Check Valve O-Ring 13 x 1.5 mm for BMW 540i, 740i, 740iL, X5, and Z8 (1998–2003)

This Original BMW 13 x 1.5 mm O-ring seals the oil check valve that sits behind the VANOS solenoid on the M62 V8 engine in the BMW 540i, 740i, 740iL, X5, and Z8. BMW gives its size as 13 x 1.5. Each ring weighs about 1 gram, and BMW's parts data shows it in production from September 1998 onward. The ring is made in Germany and is sold individually. An O-ring seals by compressing between its groove and the mating bore, so a ring that has flattened or hardened can stop sealing even when it still looks whole.

Original BMW Parts carry a 24-month parts warranty.

BMW calls this part simply an O-ring, and the check valve it seals is a non-return valve in the oil feed to the VANOS solenoid. BMW uses the same ring on the M62 eight-cylinder across four chassis: the E39 5 Series, the E38 7 Series, the E53 X5, and the E52 Z8. The 13 x 1.5 size is the identifier to match when you compare it with the ring you remove.
