Question - after parking and turning off the engine, there's a loud popping and pinging that continues for quite a while. Probably 5-10 minutes (I have not timed it). Seems worse when it's cold out. I've never heard anything like this from a car before so not sure if it's normal.
I took a quick video and put on youtube if anyone could let me know if this is something to be concerned about or normal, I would appreciate it.
