Questions about the current Legacy 2.5i Lineartronic motor

Hello, maybe you can help me there – I am looking for some information about the 2.5i petrol engine, which unfortunately is difficult to get on the internet. The engine is shown in the brochure as SOHC, i.e. single-over-head-cams, but the engine shown next to it definitely has 2 camshafts per cylinder bench, so DOHC dual-over-head-cams. Also visible on this picture is that the engine has one phaser per camshaft. Is there any information about valve control in this engine? According to the picture, the engine has a control chain, is it true or if not – how often does the timing belt have to be changed? I’m not sure about this picture if this is really the right engine. On the other hand, it’s really difficult to get information for these technical details. Unfortunately, the dealer has no 2.5r where the questions could easily be clarified on the living object… Thanks for Eur o Help! Greeting Flyerbo
