[Vwdiesel] Cleaning threads for head bolts

[David Cook]

Cut 4 grooves into an old bolt, and bring them across
the bottom so they make an "x"  which will help loosen
up any crud at the bottom of the hole.

Run it in and out a couple times, spray something like
PB Blaster or WD-40 in there each time.  

I then spray a bunch of PB Blaster into the hole and
suck it out with a shop-vac and some clear tubing
duct-taped to the end of the shop-vac's hose.

Works great.
