Ok, so I just got this 02 WRX and I know nothing about turbochargers nor subaru cars...so I'm paranoid about every new thing I hear in the car.
When I turn off my engine/car, there's a ticking noise under the hood. The ticking noise is there for a couple minutes and then it's gone. I only notice the noise after I shut the engine off. Is the ticking noise normal?
Does it have to do with the turbo cooling down?
