Loss of power, unknow oil leak by header?

Hello everyone, been awhile since i posted anything on my truck, notice this last week have lost alil power during take off, and seems to be running alil rough. I checked underneath the hood and seen this. I dont know if this would cause the loss of power, the leak seems to be coming from behind the actual header and checked right above the header to see if it was the valve cover and its dry. Any suggestions guys. thanks

Would that cause the oil leak behind the header?

actually yeah i inspected it again and its the valve cover. The loss of power tho i cant explain and another thing is that im going threw a full tank in like 3 days and driving the same distance and no heavy foot.

No but the po told me he put a 2500 stall in it but it hasn't acted like this before. How would I know if the torque converter is going out. I'm also smelling fuel.

Smell of fuel could be unburned fuel in one or more of the cylinders. Pull some plugs and see if they are wet after running. Could be as simple as a plug wire going bad.

Find you a how to read a spark plug chart online and check all of your plugs.The smell of fuel can be its running to rich or not fully burning the fuel which can be your plugs and or wires to even the distributor.I'd do plugs and wires and when you do them take one plug wire off at a time its easier not to cross them that way.

Thats the thing I just replaced all the plugs and wires like two months ago. Im thinking that its running really rich and needs a tune up to fix it. What do you think?
