well I get this gurgling sound and i have no idea what it is. have any of u had the same thing happen to u.

 

When does it happen?
WHere do you hear it from?
Etc,...

need more info

 

It happens when im going under 30mph and it is coming from the engine bay i think somthing could be loose because before i got my oil changed it didnt happen.

 

Is the oil cap on tight?
Is there too much oil???

 

I would check to make sure the oil cap is on, like KayJai said. Take it back to where you got your oil changed.

 

Make sure they put all of the caps on and that the filter is tight.
When the "top things off" they don't always remember all of the caps.
I would also check your radiator cap and your overflow container too.

 

I have the same sound coming from what sounds like the engine bay of my 01 tibby. It can really hear it when it is on idle or just above idle. sounds like it is coming from inside the vents or something like that, I am going to take it in to the dealer while it is still under warranty, but I really hate having those bastards touching my car.

 

Im goin to take it to another shop to get it looked at hopefully they will find the problem. But I did check all the caps and things like that and it all seemed fine to me.
