[C320-list] Where's the oil?

[Scott Thompson]

If you were seeing oil on the dipstick and tried extracting with the Oil 
Boy but got nothing out then the oil is still in the engine.  You have a 
problem with the Oil Boy itself, most likely.  Was it definitely sucking 
air through the tube when you pumped?  Were you using the smaller tube 
size?  (The larger tube is too large in my experience.)
