Faulty dump/bov classic sti
 

Hi

I own a Classic STi V4 . Have a problem the revs will drop and the car stalls now and again. I had it checked out and the garage person said the diaphram on my stock dump valve is split/gone.

So i want to put a new dump valve on myself. Whst dump valves are out ther on ebay and do i need a fitting kit to install a aftermarket dump valve.?

I'm on a budget so anyone can give some pointers. Thanks
