Oil plug extraction via impact wrench.
I know it seems wrong but I'm having trouble removing the sedans 17mm plug.
The Avant had a larger socket head (from memory) but needed the impact wrench
too even after 1500 miles since head rebuild.

The sedan just won't budge. 80 psi and ~200 ft lbs.  Car is Mid Atlantic salt
free.
oil filter was a snap now what?  Liquid wrench (PB Blaster) etc.  Time for
the torch?
