Hi, I don't think you dad has worked on the pistons, rings and barrels of a waterboxer. The barrels are not just installed down over the pistons like they are on an air-cooled.

well you ....but before the piston and barrel is in the engine.. tell him the pistons and barrels are removed as one piece by removing the wrist pins through a hole in the block. One hole is behind the water pump.

what can be a bit more tricky is to reach the other wrist pin at the forward end of the engine ..it has to be withdrawn though that same hole .

On every opposed four cylinder engine VW has even made.. air-cooled in all versions, and all waterboxers.. if those washers get out of place on the distributor driveshaft you can be in a lot of trouble...they like to tilt and jam on the crankshaft brass gear. A very bad thing.
