#108872, "Exhaust bolts: Bolt on Vband adapter to turbo: keep backing out" Aug-08-11 10:03 PM by streetlightning
I keep having an issue where my exhaust bolts keep backing out. they are the bolts holding my V Band adapter to the turbo... Ive tried Loctite.. no go, after an hr or so of driving and a little boosting, i notice the bolts have backed out a little, and cause a leak, i can see my wide band ditch lean b/c of the extra air...... The gasket is an "perma seal" aka aluminum gasket.. paper always fall apart.
I used the high strength high temp locktite..
They are a beveled bolt, with a flat head, so using lock washers isnt an option.
you can always trust a dishonest man to be dishonest, honestly, its the honest ones you need to look out for. you never know when they will do something..stupid

I run Hahns downpipe with the V-band flange and have never had an issue. I think you should try running it with no gasket at all. This is what I do, and the bolts havent backed out in years. No loctite or other agent used.

My hot side has been ceramic coated, if i run no gasket, i would think there would be an exhaust leak>? thats what im figthing now, a small leak, introduces air for my wide band to pick up and mess with me..
