Lexus baffle boo-boo

In order to prevent damaging the baffle inside the cylinder head cover on 1993-2009 Lexus engines, care must be taken when adding oil.

The baffle is designed to deflect oil and should not be used to support the weight of oil fill devices.

Equipment weight can place unnecessary stress on the baffle.

Placing an oil fill nozzle or other weighted object onto the valve cover baffle can easily bend the baffle.
