This is bad ... right?

Hey all,

 

I'm still having trouble with the Supra not boosting properly, and the BOV is still totally silent :( .

 

I decided to take the BOV out and inspect it a bit closer. It's mounted on the hardpipe next to battery, so I took the whole pipe out. The attached pics are what I found inside the pipes ... that's bad, right :blink: :blink:

 

I also totally dismantled the BOV, and I couldn't find anything wrong with it really, so I don't think that's my problem. How strong should the vacuum be on the small pipe that goes into the back of the BOV (HKS SSQV)? I disconnected it, and put my finger on the end of the pipe.... there really doesn't seem to be much force in the vacuum at all, I wouldn't expect it to be able to pull the BOV open! Everything worked fine before my car went off the road for 8 months. I got it back, the BOV worked for about 2 days and then just went silent. That was about 6 weeks ago now, and I still haven't figured it out ... it's getting irritating now! :rolleyes: :rolleyes:

 

Cheers, J
