Hi could anybody help. I have a 2007 subaru outback 2.5 manual with 140k on the clock it's dual fuel petrol and LPG. I've noticed it rumbling and ticking on idle and when reved up hard. It drives perfect an you carnt hear really anything. Somebody suggested hydrolic tappets or small end. They don't think is a big issue possibly cam followers. My car is immaculate and very well cared for. Any info would be greatly appreciated. Thanks all Sent from my SM-G925F using Tapatalk
