It feels like my wastegate is open at idle,
when i put my hand up next to it i can feel **** blowing out
what could make this happen?
Oh and i am not readding boost

 

What kind is it? Tials are open at idle but close once you get on the throttle a little bit.

 

I think you are wrong Islandsi, wastegate should be closed at idle, its basically a pressure relief valve.

$50 says I'm right about the Tial

 

you want my paypal address now or later?

You are thinking about blow off valves. BOV's require <u>VACUUM</u> to open. Wastegate/WG actuators require <u>BOOST PRESSURE</u> to open.

EDIT: think about it...why would a wastegate need to be open at partial throttle (which is vacuum) where exhaust gas flow is the lowest? The wastegate needs to divert exhaust gas flow when it is the highest, which is in boost.

Misread this thread. I was thinking of BOV.
You're still wrong about the Tial BOV being closed at idle though.

::Edit::
IF you have the valve hooked up to the intake mani like you're supposed to at least. If you don't have the nipple going to a vacuum source the valve is going to stay shut until the boost in the charge pipe is higher than the spring pressure in the BOV, causing it to open.

 

yeah, just lots of people have it closed, and lots open, wonder which is the intended position.

you probably have the line on the wrong port of the W/G ...

 

alright the valve that opens and closes to allow exhaust gas to exit before the turbo has a slight opening around the edges my friend has the exact same w/g and it also has the opening all around the valve too is this normal for every w/g --oh yeah these w/g are tials.

 

Do you have that ring installed onto the WG flange between the manifold and WG flange?

 

yeah.. sounds like you are missing the valve seat

Ahhh yes, the fire ring. Little silver metal gasket looking thing that you may have thrown away because you didn't know what the hell it was.
It's supposed to go between your WG and the manifold.

 

thats what actually makes the seal...

And if not installed that would explain the exhaust just pissing right by the valve and right out the wastegate dump. This would also keep him from building up boost since a lot of the exhaust is going to get routed out the dump instead of down through the turbo.

 

yes there is a ring that seats inside the flange, it is made that way for manufacturing purposes, ie so they can get the valve in there, then the ring allows for it to seat properly.
