Fix or replace oil pan on A6 Avant Quattro

[John Larson]

You said:  "I was actually looking at that stuff. There are a couple of 
brands, one
being HTS-2000 at aluminumfix.com, and the other being durafix
(durafix.com). HTS2000 is more expensive at $65 for 1lb of rods, and durafix
being $34 for 1lb. I considered one of these options just so I'd have the
rods for other aluminum repair work, but I think for a critical component
like the oil pan I'm leaning a bit more towards replacement. I'd rather not
have a sudden loss of oil and end up with a catastrophic failure of my
engine, as it's already got a whole lot of miles on it and is probably a
little tired as it is."

How would you EVER get the pan clean enough to weld?   It takes a LOT of 
work for my welding guy to get one clean enough OFF the car, including a 
trip through the giant mechanized parts washer, preheating the work to 
get any left over oil to ooze out, and rewashing the small area with 
various degreasers.  John
