How to install pistons and piston pins on Subaru Outback?

Position the piston ring end gaps at the correct intervals around the piston. Install new piston pin circlips in the inner piston pin bore groove of each piston, ensuring the correct positioning and installation in the groove opposite the crankcase service hole. Lubricate the skirt and rings with clean engine oil, then use a piston ring compressor on the number one piston, leaving the skirt protruding about 1 inch to guide the piston into the cylinder. Compress the rings as far as possible. Rotate the crankshaft until the number one and two connecting rods are at bottom dead center, aligning them with the center of the cylinder. Gently guide the number one piston into the cylinder, making sure the mark on the piston crown faces the front of the engine. Tap the exposed edge of the ring compressor to ensure contact with the crankcase. Carefully tap on the top of the piston with a wood or plastic hammer handle to push it into the cylinder, maintaining pressure on the ring compressor. If any resistance is felt, stop immediately and address the issue. Push the piston in until the piston pin bore and the small end of the connecting rod align in the service hole. Lubricate the piston pin with clean engine oil and insert it into the piston and connecting rod. Install the outer circlip in the piston pin bore groove. Repeat the procedure for the number two piston, applying RTV sealant to the service hole plug gaskets and tightening the plugs. Rotate the crankshaft until the number three and four connecting rods are at bottom dead center, aligning them with the center of the cylinder. Repeat the piston and pin installation procedure for pistons three and four. Apply RTV sealant to the service hole plug and cover gaskets, then install the plug and cover, tightening the screws.
