Hey Scotty I got a 2012 Hyundai Sonata se with 71,000mi...when I shut the car off I have a sound comming back through my air intake. It sounds like pressure is being released kinda like a slight cough..it wasn't as loud as it it now, is that normal or does something need replaced? PCV valve is new.

well, pray it's not a coolant leak or a blowing head gasket. Pressure test it for a cooling leak, and do this test for a head gasket https://www.youtube.com/watch?v=QA7KVQq9vKA

I didn't know they had test kits for that, I'll try it out and let ya know. Thanks
