2092 Dodge Ram makes a pinging sound . It's not a tapping sound . It sounds like someone is tapping on a steel pipe with a metal spoon. Any suggestions? 133k miles, never a problem before

 

I don't know they are that far ahead. Do they still have wheels in 2092???? on a serious note could be spark pinging. Does it sound like marbles in a can?? (RamMan knows more about it then I do he might chime in)

 

 

...flux capacitor at some point in the next 74 years 😄

Just kidding around. I agree - it sounds like spark pinging. I had a similar issue and seemed to have good success with switching to slightly cooler-burning spark plugs. I'm fairly certain there are multiple threads about that on here, but I don't have a link handy. I'll see if I can dig one up.

You need to be in the 3rd gen section

 

Colder plugs or higher octane gas should stop or reduce it.

 

Time for a seafoam treatment and tune up, regardless of engine.

 

Its not spark plug ping if it occurs immediately when you start up a cold engine. Ping is more pronounced to engine load and is never audible during deceleration.

 

 

Loose exhaust or heat shield
