[s-cars] Tap size needed for waste gate screw?

[Sean Douglas]

Dave:

I would recommend removing the wastegate cap and threading the screw "in"
and let it come out the other end. Then you can use a tap (sorry don't know
the size) to clean out the threads. Also, the threads have a locking
compound on them which is applied from the top side. You may consider
starting the tap from the underside to grip the threads properly.

Might as well replace the diaphragm while its apart.
