Exclamation Oil leaking around injectors

When i recently degresed my engine, afterwards i noticed that my truck was leaking oil from around the injectors, people have told me that it could be a blown head, but if my head was blowin iam sure Id notice, My valve gaskets are leaking but i couldn't find a trail of oil down to the injectors. What do you all think?

are you sure it is oil and not dirt that is around the injectors and you might have a fuel leak causing the dirt to look like oil?

it's back and it's coming out of where the injectors touch the block, and no iam pretty sure it's not from the gaskets on the valves, I smelled it and it really has no smell to it

thats wierd because there is no oil anywere near the injectors, most likely a valve cover gasket is shop, yes it is posible, or just the diesl seeping threw the seals to make it look like oil, also a posibility becasue that was my problem 2 months ago, thought it was oil and sure enough diesel leak

what do you do if your injectors leaking? what would you recomend for replacement on a auto trans 97 12 valve? nothing crazy but better than stock...that could handle like 500hp or so
