hello
I just got my oil changed at 21k miles and now when ever my car is at 3-4k rpm it sounds like theres marbles rolling around in the bottom end of my engine. It only happens when the car is in gear. If i put the clutch in and rev it you cant hear it too well, but when its in gear and you do it its really loud. What should I do? I dont want my engine to die and get stuck with another rental Kia Rio.

 

video clip the sound cuz i dunno wat you talking about and i dont believe anyone has had this problem

 

Take it to the dealer and have a tech ride with you... They'll fix it under warranty no problem.... Doesn't sound like an easy fix....

 

Take it in no problem.
