Having just replaced my 3B distributor and removed the @#$% tamper resistant
bolt (and it is indeed a bolt with a twist-off head). My advice is as
1--spread rags below/around the tamper resist bolt area to catch
2--the bolt head is a pretty smooth dome--grind a flat spot so a drill will
center on it;
3--using a small drill motor, drill through the bolt head-- I used a 3/16"
to get a start, then just grabbed a 1/4"-5/16" short bit and drilled thru
the bolt head;
4--check often for progess and when you're there the guard channel will fall
5--after removal of the hold down nut and bracket I ground off the boss that
the tamper resistant bolt went thru--(IMO-an add on to the casting by a
paranoid vp/manager at Audi), and made a tool to ease tightening/removal of
hold down nut.
I would not use a chisel. I did initially try one, but is pretty abusive to
everything and impractical especially with IM on--method I used does no
