Hi guys.
I have decided to temporarily remove the dump valve.
It's still causing problems as there isn't a big enough lip on this stock valve for the hose clamp to grip.
So I have completely removed it for now.
I'm out in the car this weekend and I don't want it to blow off again on the motorway because when it does the engine just dies and cuts out.
Let's see what noise difference it makes when I get to take the car on a trip this weekend.
That is if it stays dry. Dam this summers weather is rubbish.

Wow there are some clowns out there no wonder I can hear the turbo chatter/flutter on some cars that have taken the BOV out. In case you have not worked it out it causes mechanical shock to your turbine so not good if you want to run a ceramic turbine wheel like the CT20b or CT26 and want it to last.

You don't seriously think that Toyota put that part in for no reason do you ?

Like many things its your car so I don't care if it goes bang. People do all sorts of stupid things to their car just because "They like the sound it makes".

And yet the Japanese market ST185 GT4 has a ceramic CT26 and no BOV from the factory.

Hi guys.
Thankyou for all your replies.
I have now tried the car without a BOV fitted.
All the old connections have been blanked off so the car runs fine.
So runnng without a BOV has made no difference to the car in any way.
It sounds exactly the same. Performs exactly the same and with it removed there is no problem with the hose blowing off.
The problem I had has been sorted. Just remove the BOV.
Many thanks

Excellent , glad you took advice and got sorted without BOV. Wonder if the disbelievers still think world is flat.
