2022 wrangler willys 3.6
Hello, I have a 2022 JL wrangler with the 3.6 and 6 speed manual, noticed after cold starts the engine makes a tapping sound when coming off fast idle. I noticed this the next day after buying the wrangler when it was new, now has 2000 miles on it. Has anyone else noticed this tapping off fast idle with their wrangler? I'm worried it might be piston slap.

Pretty normal. Does it go away when warm?

It goes away right after it idles down to normal idle speed of around 800 rpm. The noise lasts about 30 seconds or less.

As long as it goes away with in a few minutes or after driving I would say your fine. Mine has done this since day one.
