Q: Roaring sound in the engine.

asked by on

Hi Brandon I recently purchased a 2011 Lincoln MKX. I realize there a kind of roaring sound coming from the engine or in its vicinity whenever the vehicle is throttling. I am wondering if it's timing chain/ belt is the caused.

My car has 184500 miles.
My car has an automatic transmission.

Hi there. The sound that you are hearing from the engine could be coming from the transmission. If you have a CVT (constant velocity transmission), then they are common to make a sound when driving them. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose the roaring sound.
