After performing a boost leak test on my 1987 Volvo 740 turbo I found that air is leaking from the thumb screw used to adjust idle speed on the throttle body. Does anybody know how to seal this? Are the threads supposed to be air tight (Teflon tape?) or is there some kind of internal seal/o ring/gasket that I can replace in order to fix this issue.
I was thinking of somehow adding a nut to the thumb screw that could be used to clamp an o ring against the threads to try and seal it up. Anyone have any other suggestions?
