Darn oil leaks

[Flooringit]

I changed injectors and cleaned the heck out of the valley. Drove it and no oil leaks. Come out this morning two drops of real dark oil so I look around it's coming from the hpop area but it's all over so cant seem to figure out source. I know it's not the lines or the back bolt no oil in valley at all. The oil in on bottom of hpop and I see it on a pipe under the exhaust manifold ( what is that pipe? ) the oil hits the lower radiator hose and runs down then drips off. I also see it on the cross member I have really big arms so it's hard to get a a can of brake clean up there from the bottom. I changed the oil and it's still gold color on the dip stick the drip was jet black so I checked the oil in the resiovor and it was jet black so I know it's from that area. Unless it's coming from manifold. I know it had oil and fuel in it from the injector change plus the bad injectors were dumping lots of fuel into the exhaust. So it's still burning it off
