There is great excitement at Bob's yard when his new metal detector is delivered. He plans to use it to find a burst pipe in Farmer Pickles' field, and promises Muck that afterwords they will hunt for buried treasure. Meanwhile Wendy sets off with the rest of the crew to build a car wash; at the site they find an old coin in the dirt. Bob soon repairs the pipe, and he and Muck begin their treasure hunt, but all they dig up is old junk. At the car wash, the Machines cannot fit the furry rollers because they are too ticklish. But Wendy improvises some 'gloves' out of sackcloth, which solves the problem. Bob detects more treasure and Muck hastily digs, only to crack the water mains. Bob and Muck have another dirty repair job on their hands, and then go to meet Wendy with no treasure to show for their efforts. Wendy plants the old coin in the soil for them to 'find'; but Muck's joy is short-lived as Wendy insists he tests the car wash.
