Q: What tool is required for the piston ring compressor operation and what steps should be followed for installing the piston/connecting rod assembly on 2015 Audi A3?
A: This requires a piston ring compressor tool. Wipe the bearer shells and locations and stamp the shells in. Re-fit big-end bearing cap, about right way up. Apply lubrication and make the piston/connecting rod assembly fit into the cylinder. Check crankshaft rotation and tighten big-end bearing cap. Refit parts (engine type).
