Look at the rear hatch lock. see that gap around it? wondered what goes there? it is this piece! subjected to ultra violet damage, this piece has long ago deteriorated. replacement is as easy as a snap and you will stop the water leak.
This part often just falls out causing a large intake leak and high idle! (we do not know why the regular cars do not have this problem) anyway we have them new on the shelf complete with rubber sealing ring.
Known as: throttle screw
