the madferrit

I fitted a dump valve to my car about 6 months ago and it has worked fine until yesterday.what happens is, when on idle the boost sits at about 0.2 below 0 where it used to sit well below that. It still boosts fine but there is no sound from dump valve when I release or change gear now. Instead its gone back to the chatter I used to get. I had the valve off and it moves freely enough. It is leaking a little air tho when on tickover. I assume its not the dump valve coz surly it would still work when boosting and releasing. What should I check cheeRS

Physio

Have you checked the rubber seal inside?

Rick

is the boost gauge fitted into the same pipe where the dump valve vacume is?

Jim Galbally

have you checked all your hoses including the one on the top of the dumpvalve going to the plenum?

also is this an ERST or a cossie?

DaveEscos

is it piston or diaphram?

if the latter then the diaphram has split

its acossie. havent relly checked anything except for taking it off and making sure it still moves which it does. It stpped for a while, then started working again and nows stopped again. I'l cheeck all the hoses but how do i ckeck the seal?by taking it apart?

Physio

Yep, just take that sucker apart dude!

the madferrit

ok took it apart and theres a small split right on the rim. Is this my problem? i assume so. Can i buy just the seal? how much if i can?

Physio

BINGO! Get yourself a new seal they normally cost about £5 - £10 or dump the dump valve cos they really are
