boost leak test question
 
1 Attachment(s)
hey i did a boost leak on my car and i found a found a few leaks.

- J pipe was leaking but i had a new gasket with my evo 9 turbo swap kit(waiting untill i get the 10.5 hotside)
-first cupler off intake manifold coudnt hold up
--both fixed

-throttle body shaft is pissing air like theres no tomorrow
-and the last is what would normally be the idle air screw(in other cars).. is it the same on a evo? and i guess there is a gasket in it?

happens to be the red # in the pic .. and im guessing the second(lower) red item is the gasket?

Yes, there is on o-ring on the idle screw. And you can get upgraded tb shaft seal from mil.spec or STM. They're both vendors on here.

i ordered the mil spec seal last night so i still need a Tb gasket and the idle screw gasket. thanks for the response ill order it today.

That seal from the factory seems to be a common issue mine was leaking there too once the new one went in no issues
