ok i think i do already have a valve seat. but i opened up the wastegate and found out one out of four lil allen screws are missing. can that be the problem? when i push the thingy up and down air leaks out of one of the missing holes. tell me what u guyz think.

Assuming the wastegate is not defective, the only way it could be bleeding or leaking exhaust at idle is if you have a vacuum signal going to the top port or neglected to put in the valve seat between the gate and manifold.

Have you figured out the problem yet? and what kind of wastegate is it?

yeah about it used and i see a gap betweeen the valve and the falnge. is there a place i can get that seal? 38mm tial style wastegate.

go to a parts store and buy some gasket material. Make your own. Razor knife and some scissors.
Do you have that ring in there? If you do you'll know what I'm talking about. Turbopimp called it the valve seat.

I think those knock-off Tials are sold on Ebay by SSAutoChrome. You might want to contact them about purchasing the ring. If not, then the Tial piece might work, but I'd check with someone first to make sure 100% about compatability.

ok quick question.. which port on the gate did u hook the vacuum line up to?

i hooked up a tube from the side of the wastegate to the turbo fitting https://honda-tech.com/forums/images...es/emsmile.gif

tial "style"? Maybe that's your problem. My genuine tial stays closed at idle.

Take that vacuum line off the turbo fitting, and route it to a vacuum source after the throttle body (ie:somewhere off the intake manifold) I bet you it'll work after that. We had this problem last night on my buddies civic. Then go get a plug for the port on your compressor housing.

Re: my wastegate stays open at idle :( (egturbo)
 

bump for this guy cuz I have the same problem right now....

Re: my wastegate stays open at idle :( (egturbo)
 

open up the wastegate and check to make sure the diaphragm and spring are both seated properly.. and make sure there are no holes in the diaphragm. just undo all of the allen bolts around the housing but make sure u hold it down tight.. otherwise the spring pressure will make the top of the housing fly off

not good. still open at idle. havent tried anything yet i need to know what that o ring thing is called. and which lines to hook up. white smoke comes out and shit at idle to rich u think? and my turbo laggggsss sooo bad. doesnt kick in till very high rpm's

hello kids.... The lesson for today is: don't beat on your car till its tuned properly

Re: (MusclecarGuyhasHonda)
 

oh and the inside of my car u can smell the exhuast makin me sick https://honda-tech.com/forums/images/smilies/emsad.gif when ur wastegate was open at idle did u smell exhaust? im not gonna drive my car anymore.

Re: (egturbo)
 

are you sure the (excuse me... i dont know the name of this part) 'valve' is closed at idle? The little exhaust valve looking thing with a long stem on it, it connects to the membrane via 2 or 4 set screws and if these get lose the membrane cant grip the valve stem, and it will be too far open. mine was https://honda-tech.com/forums/images/smilies/emwink.gif

Re: (B18EG6)
 

You need that ring to seal the wastegate from flowing exhaust past the valve...You do not need a gasket and I actually recommend running without a gasket...Use a Gasket for your dumptube and click the Vent from Outside Air to Recirculating Inside Cabin Air to keep the exhaust gases out...
