A simple, cost-effective fix for the leaking oil caps found on many S65 and S85 engines. This single-piece Viton O-ring directly replaces the factory oil cap seal and is around 40% thicker, giving more material to seal against the valve cover.
It fits the factory OEM oil cap and installs in seconds – a far cheaper option than replacing the cap, and one that has proven very effective on cap-related leaks.
Please note: Not guaranteed to cure every oil leak – leaks can also be caused by a corroded valve cover. Supplied as the O-ring only; the oil cap is not included.
