re: oil consumption...why?

[C1J1Miller@aol.com]

I've heard that high oil consumption (over a quart every 3k miles) is common
on the 20-valve normally aspirated engines ('90-'91 coupe quattro, '91 90q);
however, from other sources, the 20-valve turbo engines ('91 200q, later
S4/S6) is not known for burning much (if any) oil.  I'm pretty sure the valve
guides, etc. are the same between the two engines (and probably other
5-cylinder engines); so what is the likely cause of the oil loss?  Any
comments?  Comments about possible bullet holes through the block specifically
_not_ encouraged...
