RB20/25/26 valve cover seal washer

These valve cover seal washers are typically old, dry and hard.  You may find your valve covers leak after replacing your valve cover seals as well as rear plugs - this is the reason why.  The valve cover seal washers must be replaced for a proper seal.  They may seem expensive, and we won't argue that they aren't - however they are cheaper to buy here than most everywhere else.

You will need 10 per valve cover, or 20 for a complete set.
