How to prepare and remove pistons and piston pins on Subaru Impreza?

The crankshaft pulley bolt is temporarily installed at the front end of the crankshaft to allow for turning. If there is a wear ridge at the top of each cylinder, machine it out. The four service holes plugs are removed out using an Allen wrench so as to access piston pin circlips. In case the removing process becomes difficult for these plugs, soak them with penetrating oil and make sure that the tool completely fits into round off opening. By turning the crankshaft, place the piston at bottom dead center and remove its circlip with needle-nose pliers through these service holes. Through this service hole use either a special removal tool or a homemade one to pull out piston pins from inside them. Keep pistons and pins together; mark them for reinstallation purposes. Pistons can be left in the cylinder bores until separation of the crankcase or driven out by means of a wooden or plastic hammer handle; conversely, before separating the crankcase, pistons can be taken-out by slowly turning over onerous shaft till connecting rods push them just beyond their very slight movement limits thus inserting piston pins into such rods and then turn back cranks thus pushing pistons away from bores prior to pulling them outright.
