ADD W-1 catch can parts, I looked into ordering parts from McMaster-Carr, the stainless screens part#2930T24 and replacement orings
part#9464K142.
It looks as though they cancelled my order "due to the complexity of export regulations"
so much for US/Canada free trade!
Hardly any miles and a fair bit of rust In the past I have used rust check in a can, it worked pretty well. And you can reapply whenever you want. I would rather do it myself than have the dealership spray black rust paint on it.
