Why don't you clean it up first, then start from there. There are a lot of parts that can cause leak.

 

i did clean it up before driving it again to see where it is leaking from. I cant see where it is coming from even if im down there checking for it to leak.

 

yes looks like it could be a lot of things. rear main seal, oil pan gasket, etc etc. looks like oil. are you low?

 

maybe u need to change the cam seals and crank seal. that RTV that seals the aluminum sub pan doesn't last forever. can seep over time.

 

99 percent its the valve cover gasket... it gets frekkin everywhere..

 

i cant even tell what im looking at in your pics. go to the store and get a little bottle of engine oil dye and a black light. take the time to clean the oil residue with brake clean. mix the oil dye in with how ever much oil u need to top it off and run around town do your errands and come back and use the black light. if you do not see any signs of the dye continue to drive and check until you do follow the trail of dye back to the location of the leak.

 

I don't even have an engine leak. I plan to buy the dye and create a leak just so I can go all CSI on my car with blacklights
