I was getting her warmed up to investigate a coolant leak when I noticed it. This sounds like someone slapping down over the end of a very long pipe. Only happens at idle.i figure it's one of the many different emissions control valves hooked into it either sticking or failing. See attached video. Any advice is most welcome. Many thanks in advance.

how many miles?
wild ass guess, blowby thru the PCV valve.

Not sure don't have it in front of me at the moment once I do I will update the main post. Best guess is a lot o miles.

and pull the plugs, check for oil fouling.
the plug holes will probably be full of oil.
