[Ernie Vitucci]

That's a big puddle...What type of oil are you using? Sometimes as the rear main bearing wares...and the engine loosens up...you should/can move from 10-30 or some such to just 30wt and the dribble will slow down...long term, you need to drop the pan and measure the clearance at the rear main as well as the other two...you might need a general tightening up...also many A's will toss out the first one half quart and then settle down and not toss out much more at all...Ours has this habit.
