I did a Jakeleg job of polishing the surfaces on my turbo & downpipe. Used a large diamond knife sharpener in figure 8 patterns to level out both surfaces before pulling it all down with the V-band. Seems to have worked.

luckily nobody can see the imperfections right.? & as long as it works properly.

Roger that. The flanges on both had some very minor imperfections (bumps & gouges) that I had been told could cause an exhaust leak so I smoothed them out.

good idea.. I know where the leak is it is at that V-band.. if I yank that clamp off theres black soot on the inside of it so its definitely there..

it goes away when things warm up and I have my foot to the floor for 30 seconds or so.. i guess things expand and imperfections mate up..

I havent gone as far as to try and sand the parts or such.. I found a flange repair kit so i can cut my downpipe off and then put a new flange on.. it may be that the downpipe was never replaced when the engine and turbo were so the flange wasnt "virgin" to the shape of the turbo?

I had heard of guys trying to use a header collector gasket in there but didnt work because turbo exhaust is so hot...

its minor and an annoyance more than anything... esp since when on the highway its mostly gone as im running the engine hard enough the exhaust stays hot..

Another issue with a leaking V-Band is that there are a dozen or more different types and many sizes that are "close but no cigar". I spent way too much time reading related articles over on 4BTswaps.com as this is a very common problem.

The angles on the band are also critical and it is very common for someone to have replaced a V-Band with one that "looks right"...but isn't. You really can't tell by looking. Need to get the specs for your turbo then track down the right size & angle.

And then there is the downpipe. If it has ever been replaced, it is also possible that the flange on it is not the same as what is on the turbo.

Like I said...this topic has been a source of grief for many. Best of luck with it Bud.

I got the V-band from International.. when I talked to Jasper about my turbo, they used the stock International turbo.. I forget now who makes it... my downpipe looks old but not rusty.. but the if its been leaking for awhile then that hot turbo exhaust may very well have hammered the flange already...

and then of course theres all the talk and differences of opinion on how tight to make the clamp.. some say wrench on it as hard as you can.. others say over-tighten and it surely will leak..

im really positive they dont want me to torque down on it as hard as i can... after all im sure that little bolt is no match for those 1" steel pipes i have hanging on my garage wall in 1 foot - 5 foot lengths..... when slipped over a ratchet handle....

the whole concept of v-band seems inherently flawed to me... but then what do I know.. and really why couldnt we just have a donut gasket like on the gassers...

i would try a wire wheel on a grinder to clean everything up, it's a little bit of work but only if it truly bugs you, & you have time. i just bought new up pipes for $80 on ebay just to be on the safe side.

Door took a while and it was a headache, but after being striped down, violated chopped up, than brought back to good health, she is a heavy duty swinger now.
A little before and after.

That actually might fly in SoCal ... ain't no way in NoGa. If you plan on traveling outside the Great Golden State, you might want to just paint it beige and fly under the radar.

BTW, NICE DOOR! What's it off of? Cost?
