This sound is driving me nuts.
I took a video of the gurgling sound that the Mechanic’s day is normal. Every time a new person gets in the car they ask what is that noise. I always said I was told it was normal. I decided to take a video once and for all to see if you guys and gals think it’s a normal sound. Not the turbo whine. Listen for the gurgling noise. Can’t hear it outside the car. Only inside under acceleration. If it’s normal then fine but I need to know.

The engine isn’t moving or vibrating excessively. Is their any way to check them?

you may actually be right. If I put my hand on the rear transmission tunnel I can “feel” the gurgling. I know their are 3 mounts total including transmission. Transmission being the easiest. Should I attempt the transmission one and wait or do all 3. Not even sure if it’s something I could do

I called my mechanic and was quoted about 500 parts and Labor for all 3 mounts

corteco mounts.

I would rather not spend the money on a hunch though.
