1JZ 2JZ 7M 7MGTE valve cover seal washer
These seal washers eventually get dry and hard, and prevent your valve covers from clamping down and sealing properly. They should be replaced at the same time as the valve cover seals.
A 1JZ or 2JZ will need a set of 16, and a 7M or 7M-GTE will need a set of 12.

These washers are exactly what I needed to replace my old dried out, cracking washers that have presumably been on the car from birth.
