Recent motor melt down

["Day, John" <JDay@Charter.com>]

Does anyone have the AUDI approved maintenance schedule for a 1990 V8.
I'm looking for some facts....After dropping my car off for some general
maintenance..the motor blew. The car was running fine on the way to the
shop. When it was started to be moved into the bay the next morning, It
stalled and hasn't started since...After being towed to an audi dealer
for computer diags..a plugs was pulled and a scope enter into the
cylinder throught the hole..damage to the piston an valve where
evident..6 or the 8 cylinders hve ZERO compression.. The car had the
timing belt replaced at 60K miles an I was planning on it in the next
month or two (117K current milage). Now however I need a near total
rebuild.  
Any facts or similar experience would be welcome

Thanks ~ John
