[Vwdiesel] Cleaning threads for head bolts

[Shawn G.]

if you wanna really do it up right, harden and anneal your new homeade
tap, by heating it to a dull cherry red colour, then dip it in oil
 and let it cool off there.  You can anneal it, by mildly re-heating it
 afterwards again (not too hot, don't get near the colour change range).
