i've been running a bov from a supra, and i tried my friend's old blitz bov on there and the blitz wouldnt open at all. when both of the blow off valves are off the car, they seem to require similar amounts of pressure in order to open the valve. i know the lines are hooked up correctly and that there aren't any boost leaks anywhere. so is the diagnosis a dead bov?

 

my hks wasnt working right.. and well its really doesnt work now



so i guess they can

 

yes. im pretty sure they have seals in them that can blow and cuase boost leak.

 

springs can go bad as well and cause boost leaks

 

those too

 

Then I guess we have a sweet paper weight on our hands...

 

i knew some one that turned one into a pipe...

 

Take the blitz apart and clean it out.
I had to do that once on my Blitz DD cause it was sticking. I used moly lube to re-grease the internals but I cant say if that was the right lube for the job... either way it worked.

 

Why didnt you post this in the General car thread?
You would get quick answers, and more feed backs on questions such as this.

Yes they do go bad like other people on here said.

 

springs and seals go bad. try adjusting the spring rate(soft/hard) that might help
