6.2 liter adjustable valves?

[bangon]

Have a 2007 yukon denali 6.2 liter gas engine. Wondering if the valves are adjustable. Thanks in advance

no, ls has bolt done rockers.. only adjustments is changing push rod length, which isn't done unless you've done a bigger cam and even then most don't need different lengths.

Zoltar says it’s probably just piston slap. Our 08 YXL Denali had it. When it got cold, it kinda freaked us out.
