Ok - I am trying to test my wastegate and see if it will work before installing it. However, it does not seem to want to hold pressure. I've taken it apart, and have a few questions for the experts.

Is a small amount of leaking here, around the set screws normal?


What about a small amount through the valve stem?


Finally, should there be any sort of teflon thread dope on the banjo bolts? I am not sure if I am getting leaks here.


Here is how I am testing it: I don't have the spring installed, and attempt to put pressure on the bottom port - it actuates the valve, however there is a leak somewhere, because it will not hold pressure. This means that when the spring is installed, it probably won't actuate at all....

Anyone have any ideas??

 

Not an idea but here's a question or 2...

Did you buy the wastegate new or used?

Why did you have to "test" it before the install?

 

You're not going to like the answer - yes it was "new," however I wanted to test it because it was an SSautochrome wastegate off of ebay.....hence you can tell my apprehension. I've read good things and bad things - which is why I wanted to try it. But....as you can tell, its not seeming to want to hold pressure, which is why I am curious to know what's up.

 

theres supposed to be aluminum crush washers around the banjo bolts.
also did you put on the sealing ring that goes on the bottom of the vlave?

Really? I didn't know SSAC made wastegates. I see your reasoning for wanting to test it and retract my previous statement.

Yeah - its tough to see, but there is a crush washer between the body, and one between the head of the banjo bolt...

As far as the valve seat, it will just seal between the WG and manifold....yeah there was a seat that came with it, but I'm not worried about that right now.

My main concern is that it will actuate when boost spools up....

 

just throw it on and watch your boost gauge,how would you know if it does/does not work if it is not on the car?

 

looks like a ss autocrap one , if so theres your problem

im not trying to defend ssac but i bet if he didnt say it was an ssac wastegate,u would think it was a tial wastegate or you wouldnt know what it was,its an exact replica of the tial.have you tried it?how do u know its crap?i think ssac buys other companies **** in bulk and then sells them...ive seen the turbos they sell and they have the turbonetics "t" symbol on them.

 

I agree with eg6t

 

how do i know ? my buddy had one and it crapped out in 1 month, and i known it was not a tial cus the casting is difrent on the bottom and the tial has the name cast into it, and also the diafram is made from a diffrent materail on the tial , it is more orange in color not so redish.

 

cant go wrong with a Tial

Ok guys I'm not here to argue the semantics of SS va Tial - this gate has proven itself to other members of this board. My question has nothing to do with the fact that its not a tial. Please keep on topic.

 

Check and make sure you have cruch washers on the bottom of the fitting, and the bolt. If that doesnt work, why dont you just send the damn thing back and get a new one.

Good luck.

BTW, U get what you pay for, a TIAL may cost more but you would have had NO problem.

Yeah - well I was broke back in 2003 when I bought it. Anyhow, I've emailed them, hopefully we'll see what they say. Thanks...

 

Well - I think I fixed it, but I'm not 100% sure. I tightened the banjo bolt up nice, and I can get the valve to actuate - however, the pressure bleeds off, so I must constantly pump the pump to keep it open. Is this how the wastegate is designed?

Anyone?

 

Bump because I'd like to know the answer to this as well.

 

how are you testing pressure? no need for teflon on the banjos, they will seal fine. as long as the top is tightened down and you arent pinching the seal, it shouldnt leak or spike.

ive been using my XSpower for about 1500 miles so far without any spiking or boosleak issues. its actually .5psi higher than what the spring says though. i also have my Profec hooked up to it and run 11.5-12psi with no issues either.

 

how are u trying to make it hold boost with no spring???
