i have a drag manifold with a t3/t4 turbo and the 4 bolts on the manifold and turbo flange keep backing out. Why? the same goes with the downpipe. i have a external wastegate with a closed flange on the downpipe.does anyone know what i can do to prvent this?i dont know if i should use locktite because i might want to get them out/

 

have you made sure you are torquing the bolts to spec, the turbo manifold's bolts might need to be tighter than the stock bolts you were used to.

 

what grade bolts are you using? I'm going to hazzard a guess that the bolts are yielding from the heat. Loctite wont help in this case because it's only good up to something like 300 F.

 

try putting some blue locktite on their... i believe that is a little weaker than the red locktite

 

use green locktite. it should help hold bolts in and still be able to remove.
