2013 F150 Ecoboost 3.5 Sport 2WD with a 135k on it.Its been sitting for two weeks straight.My son drove it yesterday,and at 2k rpm’s it started to make a wining/light roaring noise when accelerating.Truck runs fine at idle and when revving up in park.If I can’t fix myself,I can kind give the mechanic an idea of what it could be with the help from yall.Appreciate any info

 

Are you sure it's from the engine compartment kinda sounds like it could be a wheel bearing.

 

Not nearly enough info. Turbos whine and engines roar a little at 2k rpm.

 

Does it get louder the faster you drive or when making a turn. If so if it louder turning left it would indicate the rh bearing.
