Leaking Coolant

So I recently did a cam install and I've noticed I'm leaking coolant. Today I finally found where. I think its leaking from the waterpump onto the waterpump driveshaft because when I start the car it slings the coolant from there when it starts spinning. What do I replace to fix this? Would it be #156's here?

No, that has nothing to do with coolant. Those o-rings are just to keep dirt out of the greased spline drive teeth and coupler. What is more likely is that coolant is coming out of the weep hole that is above the crank pulley. Then coolant gets slung all over. Probably time for a water pump.

After looking closer, I think it's actually OIL that is being leaked on there and thrown around. Would this be the waterpump driveshaft seal in the timing cover?

sound like it. When I had my lt1 I had a leak from that exact spot. Paid $300 to have all new seals put in the timing cover and still leaked. Ended up being the water pump drive had a groove worn into it from the seal. Be sure to inspect that when you tear into it.
