Sounds like a pressure cooker
For the past 3 weeks or so, my car has been making a noticeable intermittent pulsing hissing sound from what sounds like the front passenger wheel well area. I have no engine codes. Turning off the A/C does not make the noise go away. The hissing noise seems to cycle on and off will last for about 30 seconds then go away for a bit then return.
I don't have access to a lift, but its sounds like it is coming from a an area towards the bottom front passenger side of the engine. I'm not losing any oil or coolant. The pulsing sound of the hissing increases with the engine rpms. The noise seems to be audible only about 10% of the time the engine is running which makes the exact location of the sound hard to pin down, as I've only been able to pull over and try to search for the sound while it was audible once.
What could this be?
