Replacing Intake Plenum and catalytic converter

What are the torque specifications for replacing the upper intake plenum on a 2002 Impala LS w/ 3800? Car was leaking anti-freeze from the passenger side near the PCV valve. Plastic Plenum was warped in the corner. Probably should not complain I have 197,000 miles and this is the first major repair. Also replacing a catalytic converter, what is the torque specs on the exhaust joints? to bad it is over the warranty. Been a great car!

The specs should be in the manifold kit you get, no?

Scroll down a few pages for the exhaust torques.

Thanks for the info. Parts should be here tomorrow.

easy job! Save yourself some money and do this yourself. Total out of pocket cost to me was $98.00, and only took three hours of my time.
