A6 4.2L - pros and cons?

[Taka Mizutani]

The issue with Sport Quattro engine is porosity of the castings- a bunch
were replaced with "standard" iron block engines much like what is in a 20v
UrQ because of these issues.

I never heard that they pulled engines out of customer cars so they could
use the engines in motorsport- that would not have gone over well.
