i just got my wastegate in the mail today and it came with this o-ring that goes between the wastegate flanges
but when i put this ring there it puts a gap between the flange and the gasket?
should i just not run the o-ring in between or what? thanks alot!
I’m pretty sure you need that ring, not sure about the gasket though. From what I can see, the ring pretty much looks like it acts like a gasket. I don’t think mine sticks out as far as yours.
Edit: Pic for comparison.
Also if you notice when you take the ring off, there would be a leak because the valve doesn’t completly seal.
does it go narrow side in and flat side level with the flange?
thats the “fire ring” you are refering too. yes, you need it. the bevel side goes into the wastegate, so it should be flat where it meets your manifold. you can use a gasket, but it’ll eventually melt, and blow out, thus causing a leak. the fire ring acts as a gasket like elusiveguy said.
hth…
well i have metal gaskets so hopefully they wont blow out, but thanks alot!
if you bolt the wastegate down to the manifold, the ring will press into the wastegate and sit flush. its suppose to be a really tight fit so it won’t leak.
metal gasket will work… but yea what they said
