  Kinda depends on the noise.  MY first thought was a blown head 
gasket between 1 and 2.  That wouldn't really explain the noise but 
it'd explain the lack of "falling out" when the line's opened.  My next 
suspect would be injectors if the noise is more harsh and lower in 
the engine.  If it's lighter and definitely high in the head then yeah, 
look at the lifters.
  Pull the valve cover, rotate to the lobe up then pry on the lifter.  
The squishy ones are the "bad ones".  That's basically the Bentley 
test as I recall.  Pretty much did it for the Quattro.
