Common oil leaks on ka24de?

Hey All,
I just purchased a pretty bone stock s13 fastback a couple weeks ago. The whole underside of the engine is covered in oil and grime. Before I tear everything apart, I thought I'd ask what the most common areas on the ka are that leak?
Thanks all!

Ps pump / hoses, oil pan, front main seal are common

Front main seal is the worst leak. Next is oil pan gasket if it's old, which a lot of times it is. Next common one for me is probably valve cover gasket, especially with the older gaskets having cam seal plugs being separate pieces rather than integrated like the new ones. PS pump could get bad but I haven't seen many that were leaking profusely.

Ran some UV oil dye through it, turned out it was the front main seal and the oil pressure sensor that were leaking. Got them switched out, going to take it for a spin and see if the oil pan gasket is leaking as well or was just dripping from the front main seal.
