Wastegates

[firkins@eis.net.au (John Firkins)]

I've got a prollum with the wastegate on the 82 Ur-Q.
The pipe leading to the wastegate that supplies boost pressure is loose &
needs to be resealed. i removed the banjo bolt that fixes the pipe to
wastegate & found that I've removed a substantial amount of the thread
along with the bolt.
Has anyone had the same prob? If so whats the fix, helicoils? or replacement?

The second problem I have, How do you get the wastegate off? i've unbolted
everything but the nut holding the poppet valve.
I'm reluctant to use much force coz I cant see a way of stopping the shaft
from rotating & tearing the diaphram. Whats the trick?

TIA
