With the threads still somewhat good, the first step should be a self
tapping oversized oil plug. This should do the trick. Be sure to get one
with the proper sized flange and try the fiber or nylon washers. Why VW used
copper against aluminum takes me by surprise.

Subject: tired oil drain plug threads (case side)

Hi Folks,
�
I was wondering if anyone has had experience & could tell me about "what" to
use for thread insert (helicoil etc) on my 90' 2.1L motor.
�
I did an oil change last night and the threads are getting soft, am afraid
the next oil change will mean doing an insert.

Thanks,
Brian T.
