[s-cars] Thanksgiving Misadventure

[Keith Franchetti]

Hi All-

Just thought I'd report that I seem to be up and running 100% now, though I
hesitate to say that for fear of angering the Audi gods.  We'll call it
97%!

Switched in a newer used OEM coil over the weekend (thanks to some great
detailed directions from a couple of different listers--thanks!!!).  Not
many test miles in yet, but no hiccups under full boost now, or coming out
of slow turns in 2nd gear.  BIG difference.

So, to wrap up, after my Thanksgiving Day disaster that (in addition to
ruining the holiday for the family), I though might cost me $2-3k in new
cylinder head--the whole repair only cost the price of the TimeSert kit,
the valve cover gasket kit, and a bit of time.  (Oh, and it also cost me
having the car hit by the sand truck, since it wouldn't have been parked
there if not for the tow I needed.)  Well under $300.

Again, many thanks to you all for the invaluable help!

Keith
