It’s when I first start the engine, it’s not the injectors. I had a 2017 and had the engine replaced the cylinder was honed wrong causing piston skirt to slap in the bore. my new truck is doing the same thing.

It worse in gear when a load is on it, you can hear it some after it warms up

Can’t believe this is happening to me again. My 2018 had same issues so disappointing

Took it to my dealer they told me they scoped the cylinders but never did and gave me work order stating they did with no scoring. I called service manager because no one had touched anything under my hood and he admitted they did not scope it. What a joke !!
