Manifold/turbo blowing
Turbo Mini Forums

Ever since I've been running my t3 standard setup I've had a slight blow on the exhaust manifold-turbo joint,
I inspected it and the mating surfaces on both sides appeared to be rather pitted with an uneven surface, managed to scrape back most of the carbon build up to make it a bit better.

Was just wondering if anyone has come across this and has any tips ideas on how I can stop it from leaking?

Cheers

Low boosting for now.

there is a gasket you can use

Done now needs redoing lol

It's got a gasket i replaced when building thanks.
I was referring in terms of like maybe a fire putty I could use? Or a method of flattening off the mating surfaces

Ive found ust firegum and no gasket works well, or making a gasket from copper.

if you have tightend it down enough the gasket should seal it, you could try some exhaust putty or sending the turbo and manifold to have both faces machined

Done now needs redoing lol

I do what Joe C says

Okay cheers joe. My dad suggested maybe using some "quicksteel" to fill in the pits to bring it up to a neater level.? Could possibly work?

Even so, appreciate the ideas people :)

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Yes, get the surfaces machined and then use a new gasket......as good as new then.

i hand filed mine then finished the bits off on an oil block ( sharpening stone) i also have a home made annealed copper gasket @1mm no gunk stuff and not a single spot of leakage

Yes i moved to the darkside

I'll go down that route then and get it sorted for good rather than have to rip it off again in the next fortnight. Lol

Cheers guys!

Also Brett, how long did it take by hand?
If I can do it myself I will :)

20 mins with the file i did it on the exhaust manifold to head flanges aswell as the centre branch had warped no exhaust gasket issues for me ( i used the same gasket 5 times atleast aswell )

Yes i moved to the darkside

Oki doke I'll look into that when I sort out my proper turbo head!
I had that issue to start off with when I used a "quality metro turbo gasket kit" which supplied a cardboard mani gasket, went and brought one of the perforated ones and worked fine :)

Low boosting for now.

I used a file and, belt sander, then a fine smear of fire gum..

Edit. With a new gasket of coarse..

Also would this be the reason it's taking over 4000 rpm to get full boost?

Sounds about normal for a t3
