That's actually sounds like the valve cover (head cover)...

All the little ones that use the 8mm socket are 80 in-lb

The bigger one in the middle is I think 17 ft-lb

most of them are all 8mm bolts.. theres a 10mm i think in the middle.. ya this is the valve cover.. cause the part i took off had the 4 big covers for adjusting the valves.. but i found a chunk missing off the gasket near front left side where i noticed the leaking.. there are abunch of small bolts.. like 8-9... which get 80in torque.. 3 really long bolts.. 17ft torque.. theres 2 thats a little smaller than those 3 big ones tho... they get 17ft too?

Only the one with the larger head is 17 ft-lb. ALL the rest are 80 in-lb.
