my wastegate is open even at idle, not a lot but you can hear it poping a little bit out of the dump tube, but if I am driving and pressing on the gas it will close,

how can you tell if its closing while driving? as long as it holds boost steady and opens on time you should be fine.

Bimmerman

well it kinda messses with the idle, and the car will be noisy but if you give it a little gas the cars get quiet, plus you can put your hand under the dump tube and feel it coming out at idle.

Let me guess...you have a Turbonetics Deltagate W/G? just wondering..

LOL I "USED" to have one and the damn thing would boost creep occassionally. Sell it and get a TIAL if I were you guys.

I have a tial

do you have the metal ring in the wastegate? with out the ring the wastegate will leak out of the dump tube.

I would bet that's your problem, either that or tial forgot to install a spring.

I had that same problem with my 40mm Tial, it went away after I hooked up the vacum lines the right way.

Bimmerman

it has the metal ring, but when installing I noticed that the ring wasn't level with the base of the flange is it supposed to be? all so what is the correct way to hook up vacuum lines?

s2kdre

the best vaccum source is from the turbo.

Bimmerman

my only line coming out of the turbo goes to my boost controler then to the wastegate and thats it how shouyld it be hooked up?

no2unenolife

side of wastegate port connects to my turbo port,
top of wastegate port connects to boostcontroller to vacuum source

Bimmerman

ok here is how I have mine, side of turbo hooked to boost controller other side of boost controller hooked to side of wastegate, top of wastegate hooked to vacuum source

Mr T

I would say that you need to remove the top line that goes to vaccum it is going to open under vaccum at idle if you have it hooked up that way . `its also going to over boost cause the gate will not open if you have boost going to the top port ... depending on what boost controller you have you may need to let the top port vent .

Bimmerman

solved the problem, had to take apart the wastegate and install the lower have to the manifold first then mount the top half back on, now no leak
