Re: Cracked EM...

The point of the cracking manifolds, their being replaced
with 2-piece manifolds, and the potential difficulty/cost
od obtaining replacements reminds me: Due to lots
of occurences of LT1s (as well as L99s, the 4.3l version
of the Caprice version of the Camaro version of the
Corvette engine :) in Caprices having their right-hand
side EM crack, GM has (besides a manifold that is
split at the engine end for the last 1.5 years of production)
a TSB that says to saw the engine-facing side of the
identical-to-stock replacement EM in half on the older
cars, thus reducing heat-expansion stress. 
Maybe something like this is possible on the
1-piece Audi manifolds? (such that it's still one piece,
but the 2 "halves" are joined only at the downpipe end)
