That part 89570-60070 is for one of two vacuum switching valves (VSV) that work with the Air Injection system. It is the VSV (2).Can anyone tell me what this is and what it does. On the drivers side by fender. Looks like a mouse chewed off the wires on top. Thanks!View attachment 2896522
It sounds like you have a place where air is entering the system. Maybe a pinhole that isn’t quite leaking yet but allows air to build up. Replacing the master clutch cylinder and slave cylinder are very easy. They’re not expensive either. I would also replace the line between the two. It’s a couple of bolts and then you bleed the system the same as you do with the brakes. If that doesn’t fix the issue then Toyota may be correct about needing a new clutch. The clutch works until one day it doesn’t, generally.Been having fun fixing up the old girl but have another question for you knowledgeable folks. I took the rig in to have some rust repaired(the guy did a great job!) and I noticed the clutch pedal was getting soft. When I picked it up it was so soft it wouldn't shift into gear. I was able to pump it enough and limp it into the local Toyota shop. I did pop the clutch cap off and noticed there were bubbles when I pressed down on the clutch pedal. It doesn't seem to be losing any fluid. Is this something that maybe needs to just be bled or is the slave or master shot? Of course the Toyota dealership told me the clutch itself needs to be replaced which I can't afford and honestly don't think its bad as it has always shifted just fine. FYI the rig sat for about 10 years before I got it. I did add the transmission to transfer case bypass hose. That shouldn't have any affect on this correct?
Thanks for any help/advice!!!
