H3 H3 Valve Cover Gasket Replacement

[Hummer H3]

I got to work and noticed an engine oil smell and when I parked saw smoke coming from the engine bay. Popped the hood and noticed oil on the exhaust side of the engine. It looks like is coming from the valve cover but could not duplicate the leak revving the engine. Next I'm going to fill the oil to recommended levels and see if the oil starts leaking with the engine running. I'm pretty sure its the gasket. Has anyone had similiar failures? Has anyone replaced the valve cover gasket? Any info will be appreciated!!

Check the the front cover/oil pump area, thats where mine cracked & sprung a leak. It's #16

Put 2 quarts in today and started the engine. Found the leak coming out of the valve cover gasket. Now I'm tearing it apart. What a chore!!!

Some important torques:
Intake manifold Tighten the bolts from the inside working outward to 10 N·m (89 lb in).
Throttle body bolts (if removed) Tighten the bolts to 10 N·m (89 lb in).
Camshaft cover bolts Tighten the bolts to 10 N·m (89 lb in).
