The Audi V8 engine is actually quite light.  Complete engine weighs  473 lbs,
including all auxiliary units.  The cylinder block is cast in  hypereutectic
alloy of aluminum with a 17% silicon content and weighs only 62  lbs.

The cylinder heads, oil sump top section and toothed belt housing are made
of aluminum.  The valve covers are die cast magnesium and coated with a  thin
synthetic material to prevent corrosion.  I can tell you that this  works.  I
can wiped off the dust of my valve covers and they look brand new  on my car
even after being 16 years old.

The only steal parts in the engine really are the crank and cam.  Even  the
connecting rods are forged from aluminum alloy.  They are 154mm long,  20.5
wide and weigh 621 grams, including the bearing.  The aluminum slipper  skirt
pistons are electroplated with iron, and then thinly coated with  tin.

They are a great car, and I love driving mine.  My friend who is a
Porsche/Audi mechanic had one in the shop with 465,000 miles all original except
maintenance, another one with 375,000.

If anyone is looking for any V8 parts including a complete running engine,
PM me at _UCMYVW@aol.com_ (mailto:UCMYVW@aol.com)  or Call 570-403-5054  and
ask for Geno.  He recently smashed up the front end and is parting it  out.
