Inside bubbling noise
 

I have about 4K miles in my card but I noted at around 3.5k mark a new noise when idle. The noise can only be head from the inside and only happes in idle when the car if fully warmed up. It is not loud and it is like a bubbling noise like a air valve opening and closing. It is kind of erratic but it is always there.
It is not bordering me i just want to know what causes it.

I used to have this noise too. It went away when I had the HPFP replaced. So, I'm guessing it's something that's related to HPFP.

like this?

I have this noise as well.

So you're saying my car is getting stoned :w00t:
it is sort of like that; more like number 3 here (without the high pitch noise)

I also have the crickets, since mile 100

is it definitely a bubbling, or is it like sloshing? We had a honda Fit with bubbling/sloshing and it was an air bubble in the coolant near the heater core.
