Hi all, I've noticed when I first start up my Legacy GT-B in the morning, there's a bit more mechanical noise, sounds like valve tappets maybe. Goes away within a minute or two. Once the engine is at operating temp there's none of it. Has anyone had the valve clearances adjusted on their EJ20/206/208 engine? Is that supposed to be a maintenance task at a certain KM mark for these engines? Maybe it just needs some Seafoam. Thanks. G.
