108872, Exhaust bolts: Bolt on Vband adapter to turbo: keep backing out
Posted by streetlightning, Dec-31-69 06:00 PM
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.

any tips?

here are the parts (minus that 90 degree bend)

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.

If you have a welder you could put a small tack on each bolt to hold it in place. You shouldn't be removing them that often

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..
