What is the rocker arm torque settings for 2001 Chevy Malibu 31 liter?

There isn't a single torque specification for rocker arm adjustment on a 2001 Chevy Malibu 3.1L. Rocker arms on these engines are typically not torqued. Instead, they're adjusted using a lash adjustment procedure. This involves using a feeler gauge to set the correct clearance between the rocker arm and valve stem.

The service manual for your specific year and engine will provide the correct lash specifications (measured in thousandths of an inch). These specifications will differ between intake and exhaust valves. You absolutely need the factory service manual to perform this adjustment correctly. Improper adjustment can lead to poor engine performance, valve damage, or even catastrophic engine failure.

You can find a service manual online (often as a PDF download) or through a local auto parts store. Attempting this adjustment without proper information and tools is strongly discouraged.
