Trust Type R Leak

[grepin]

Has anyone had any problems with these BOV sticking or leaking?

I may have this problem.

I take it you have tried tightening the valve?

How old is it? They are pretty easy to rip apart and inspect. Check the diaphragm isnt damaged, and while you are at it see what tension the spring is...i recall they come with two tensions, one is very hard, the other pretty soft. (Harder spring usually causes a bit of reversion at low boost rpm bacvk thru the filter...its that hard)
