2010 Escalade horrible Piston Slap 6.2 

There's the noise. I'm gonna sleep easy knowing that my engine doesn't have rod knock.

My 2011 Escalade with the 6.2 sounds the exact same. I’ve put 100k on it since the noise started and it hasn’t got any worse. The truck now has 290k miles and runs great, just piston slap from hell when it’s cold.

I have a 2010 Escalade esv that dropped a valve seat and bent pushrod, blew piston and wrist pin into the cylinder through watch jacket.. ended up just putting a 5.3 in. Heard nothing but garbage about the 6.2s

Would love to hear more on the subject. GM says normal?? Any fix other than a rebuild with new pistons?

Mine has piston slap as well. But it will only do it cold under load (driving), then will stop after driving for a few minutes.

My Denali 1/2 ton 2013 sounds like a diesel on cold start then stops when it warms up is there any oil additive that helps
