1998 454 k2500 oil leak

[Sniperinhisname]

Hey, I just bought a 98 suburban k2500 454 and it has an oil leak, I'm not sure if it's the rear main but it's dripping on the exhaust cross over pipe, and off the starter, and around the oil filter and oil cooler lines. Im probably going to have to replace the cooler lines because im pretty sure they are leaking but it Makes me think it's something high on the rear of the motor is leaking for it to be dripping down on both sides. Do you have any ideas on a common leak in that area or do you think it's my rear main?

Valve Cover gaskets and possibly your oil pressure sender. Fighting the exact same leaks on my truck as well. Thought my rear main was pouring oil out until I saw it dribbling down the back of the block and noticed oil buildup around the exhaust manifold and in the nooks and cranny's of the head.
