I started the car today as usual and as soon as I turned it on it started making these popping kind of sounds while idiling and when I revved it and I’ve never heard this kinda sound before. I haven’t done any pulls lately and It was completely fine yesterday so I don’t know what could the cause of it be. As for the oil level, I’ve been checking it weekly and it has never been below the full line and I still have 3500km until the next one, I’m gonna take to Hyundai for an inspection also but if any of you guys have an idea to what it might be I’d greatly appreciate it. It’s a 2013 3.8 GT
