On the 2003 Astra 1.6 16v, the breather pipes are typically located at the top of the engine, near the valve cover. One common breather pipe runs from the valve cover to the air intake system, while another may connect to the crankcase. It's essential to check for any signs of wear or damage, as these pipes can affect engine performance if not functioning properly.
