2010 Engine Start-Up Noise, Normal?
Upon cold start-up, I notice that the engine in our 2 Forester XT's to be really rough sounding and loud. The sound to me seems similar to diesel clatter. It only last 10 - 20 seconds. Doesn't seem normal to me, but we are first time Subaru owners.
When the engine is fully warm everything sounds normal.
Also, I notice that sometimes there's a sound similar to the sound a car makes when there's an exhaust leak when accelerating.
We only use high octane fuel. And the cars both have around 800 miles.
BTW, it's summer time here temperatures 80 - 95 degrees. Not winter with its freezing temperatures.
