Sometimes when I drive my car it makes a mild howl whenever I accelerate. It runs fine!

Is this sound normal?

Thanks for any input you may have!

 

have you removed anything with a metal gasket, then reused the SAME metal gasket?

 

I wouldn't know. I just bought it few months ago. Would it be the turbos going bad?

 

when the turbos go they usually make a dentists drill kind of noise. check to see if you are leaking any oil from your turbos. remove your skid plate and see if there is any oil on it.

i mentioned gasket because when i had first changed my aux. water pump i removed my throttle body to get to it. when i put everything back together i re-used my original gaskets on the throttle body. the car made a howling noise due to air leaking when i drove.
