Lately, I?ve notice a noise which I can only describe as when a vacuum cleaner is clogged (trying to intake the same amount of air through a smaller opening); or as if a turbo has just been triggered.
This occurs through all RPMs but it is more audible as the RPMs increase, to the point where I can hear it even at highway speeds.
Initially, I blamed the air filter I bought from a local auto parts store. But the noise remains even with a different filter.
The Disco runs smooth and fuel consumption is normally low at around 13mpg combined. There is a ticking valve noise which has been present since I bought the truck 4 years ago, and hasn?t gotten worse (though it still bothers me).
While the truck runs smooth, I feel ?it just might be my imagination- that it takes is just a bit longer to get up to speed.
Any ideas as to what is causing the ?turbo noise? and the possible loss in performance?
Thank you
