Control valve-stem lubrication and keep oil from slipping past the valve guides with the MAHLE Engine Valve Stem Oil Seal Set SS45937A. This set drops in as a direct-fit replacement for the listed applications, including the 2002-2018 Toyota Camry, 1998-2022 Toyota Corolla, 2001-2018 Toyota RAV4, 2010-2020 Toyota Prius, and 2005-2016 Scion tC — see the Buyer's Guide tab for the full list of 29 vehicles.
Valve stem oil seals cap the top of each valve guide and regulate how much oil reaches the moving valve stem, helping keep excess oil from being drawn into the intake tract or pushed out through the exhaust. Signs the seals may need replacing include blue smoke at startup or on deceleration, rising oil consumption, and oil-fouled spark plugs. If worn valve stem seals are the cause of those symptoms, this set replaces them — diagnose the cause first, since oil burning can also come from worn rings or guides.
