[Vwdiesel] Help - messed in the head...

It sucks how letting anyone else touch part of your car leads to that
part being screwed up :(  I'll never forget the place in Logan Utah that
did an inspection on my Vanagon, knocked the press-on drums off with a
sledge (before confronting the owner I quietly asked his son, who
innocently acknowledged it), warped them beyond repair, denied doing
anything improper, and when he finally agreed to replace them and gave
me a ride back to my office, agreed with me when I told him that what I
liked about Utah is how honest everyone was.  I could hardly keep a
straight face on that one...

I had my TD head valve seats and guides done recently... I brought it in
for the initial cleaning and had to come back later because I hadn't
brought them the prechamber inserts.  Huh, the sealing surface of the
head now has a big gouge in it... sigh.  Ok, so there goes the 1-notch
gasket I already bought :(  I did get semi-lucky though, the guy called
me when one of the prechamber inserts wouldn't stay in place.  He was
afraid they would get pulled up by the cutting tool, just as yours may
have.... he suggested we jbweld them in place, I gave him the go ahead,
it worked.  I haven't dared to look at them closely since then :)  Nor
have I had the courage to figure out the new clearance, if I can even
think of a way to do it... they couldn't give me the exact amount of
metal they milled off the head... it'll be at least a 3-notcher now
though, based on what little information they could give me.

So I know just how you feel :)
