I noticed after bolting my manifold and turbo together that Ive got a small gap. I can slide a metal scale in there and that measures .016 on the vernier, real tight in some spots but I can get it through

Now I know a lot of **** obviously isnt always true but is .015-.020 thou to much and will just leak like a mother ******?

Its to cold for me to want to take it apart and get it remilled plus Id be weary of my turbo being milled

Do you guys think it will leak? Will exhaust carbon plug it up right away?

Anyquick fixes? High temp sealnt that I can kinda line in there to fill the small gap?

Special Feature High Temperature
Tensile Strength 2.55 MPa (375 psi)

Would that work?

 

why not just get it resurfaced by a machine shop?

Ya its my turbo I think that is warped, flange on mani was perfect, its not huge warpage though

 

 

.015" will definitely leak. You could take it apart and put some sealant on it and reassemble, but if you're going to take it apart, i'd get whatever is not flat resurfaced instead. What manifold is it? I've never seen a turbine housing that wasn't flat, since they're cast.

 

The turbo is a used t3 .60/.63, it looks previously machined/ground

Im just gonna try and flatten it as best I can with a straight file and maybe a sheet metal gasket or maybe even tinfoil? I can make

This stuff is awesome.. my buddy uses it on his single digit race car instead of gaskets. (why buy new gaskets all the time?) It comes in a tube for a caulking gun as well..

not sure what you mean by 'line in there'? you'll hav eto take the turbo off and put a decent bead on the flange. I bet it will hold just fine!

I use this stuff aswell. Works really good.

 

I 'third' that.

Good stuff/

 

Ultra-Copper is good stuff, but not to make an exhaust gasket. I think it is rated at like 400 degrees.

 

how bout this stuff - 2000 degree stove/gasket cement

its fine ive used it on downpipes and wastegates without a problem.

 

Anyone else agree that the copper rtv will work with a manifold flange?

Im gonna take the turbo apart tomorrow and file as good as I can, I need something I can pick up locally

 

i guess its worth a try if your not willing to have it milled

 

You do know that they make crush gaskets in the common turbo flange sizes, right?

I'd try that before half of these goofy silicones.

 

I dont have 2 weeks to wait for this gasket to get to canada

What about tinfoil? That fills the gap, crushes and is metal...

 

do you guys have parts stores up there? they sell metal gasket material in sheets you just trace out the flange on it and use a dremel/tin snips to cut it out.

 

They only sell this gasket mat for valve covers or stupid **** I believe

I could use sheet metal, but thats fairly thin and I doubt it would crush

tinfoil seems like it would work though right?

 

you could buy a thin sheet of copper and anneal it

 

anyreason why tinfoil wont work?

ive got it apart now, might file it down before I go to bed and assemble with 5-6 layers of tinfoil and squish them ******* down tight with allen bolts n nut

 

tin foil will melt... i melted the factory exhaust gasket between the manifold and head when it was warped.. i'll have to post a pic of that some people might get a kick out of it

 

since you're gonna take it off and apart anyways, why not take the parts to a machine shop to mill flat for a couple of bucks. Might jsut be the flange on the manifold, which would be even cheaper

hmm.. could you not go to a dealership for this then? if so, what year/make/model?
