My wastegate gasket is always blowing in this one spot. Can i put some liquid gasket on the new gasket to ensure a better seal? Won't fugg up anything i hope....

 

from what ive read i think you should try not using a gasket

 

i tired that...the leak is even worse.

 

well im not sure but i would try some high temp silicone like rtv type stuff

 

Get the turbonutics wastgate with the silver ring around the inside, mine has not ever blown it's been six months.

 

sounds like something is warped, check for flatness of mating surfaces, you may need to get either or both flages straightened by milling. see iff you cant get someone to put an o-ring receiver groove on the wastegate or a gasket with oring in it.

 

I bought 2 of the good gaskets from ATP and am using them(one mani to wg, other wg to dump)

 

yeah, check for straigness, I never use gasket and never leaks...sometimes the cheaper gasket casuse leaks than having no gaskets

Do you still need to use a gasket if your wastegate has a metal fire ring?

yep sounds like one of the surfaces is warped. I'm not using a gasket (blew both tial gaskets) and am having no problem at all.

 

NO leaks at all with no Gaskets? I mean when i didnt use a gasket it wasnt "that" bad. Just you could see some black areas around the manifold/wg where it was kinda seeping....

The manifodl is an SFP.


If you can visualize where the WG is and how its positioned.....it leaks right where they meet. on the edge. Just teh weight of the dumptob and the WG itself i guess makes it leak a bit. I really don't wanna take apart all the crap to get it milled....ill try some copper gasket stuff i got in the tool box first .

 

i kept blowing the same gaskets, turned out that the flange was warped... took the manifold off and grinded the flange down til it was perfectly even and put some high temp silicon on there and its fine now...

 

yep, no leaks at all.
I've ran that way for about a yean now.

 

Simple fix. Just use rtv like you were originally thinking. I had the same problem you did and rtv worked perfectly. It lasted a good year for me till I had to just pull it off and redo the rtv because there was a tiny leak. The gaskets kept blowing for me as well. I checked the flange and it's very slightly warped, but it's not worth the time of getting it decked imo. Just use some rtv and ur good to go.

So the question is, should gaskets be used? Or is it meant to be run without if both surfaces are perfectly flat?

 

can RTV withstand the heat from the manifold?? it does get quite hot...

 

Gaskets are always "supposed" to be used imo. It's just that sometimes you can get away w/o using them...

RTV can EASILY withstand the heat.. If you read my post, mine's been on for over a year.. I forget what the rated temp for rtv is, but it's pretty high. It's not uncommon to use rtv as exhaust gaskets.

I ended up using some copper silcone liquid gasket stuff. Thign said it could withstand 700 degrees....i made a coupel runs it seems to be holdin aiight...we'll see.

I blew mine out and used the same stuff. It seems to hold up pretty well so far. (5 months)
