Original BMW Camshaft Rectangular Seal Ring for BMW 5 Series, 6 Series, 7 Series, X5, X6, and Z8 (1998–2022)

The Original BMW camshaft rectangular seal ring, part number 11-31-1-705-512, helps seal the VANOS camshaft adjustment unit on BMW 5 Series, 6 Series, 7 Series, X5, X6, and Z8 models (1998–2022). VANOS is BMW's variable camshaft timing system, and it uses engine oil pressure to move the camshaft adjusters, so the seal rings at the unit have to hold that pressure. BMW's parts data names this part a rectangular ring. Within the models covered here, the same ring runs from the M62 engine in the 1998 540i to the N74 in the 2022 M760i xDrive.

Original BMW Parts carry a 24-month parts warranty.

BMW has carried this number through several engine generations, and it replaces the earlier ring 11-31-0-150-789. The change is marked exchangeable retrospectively, meaning the current ring is correct for cars that left the factory with the older number. The ring also carries a second BMW cross-reference, 11-31-1-439-534, so paperwork showing either of those numbers points to this part.
