Whilst working on the 3VZE Motor of my 1994 4Runner, my Mechanic noticed this damaged unit, and has requested I get a replacement.. Only I have no idea what it is..
I'm a parts counterman for a Toyota dealer, 22 years now. That is a vacuum switching valve, looks like part# 90925-05047. List price is $90.54. We still stock them, and they are still available nationally.
I am over in the UK so have found a local supplier..
