Im changing my injectors and about to bolt everything back together (uim) well i looked down into the LIM...what i saw looks to be like coolant....anyone ever experience this?

the coolant only appears above cyl 5 in the manifold and the car also had a bad injector which i had to drive for 45 mins to my house

 

i had either coolant or oil in my UIM

 

I got it cleaned up and hopefully itll be fine...i checked my gaskets and it seemed fine

 

pretty much what i did, bypassed and removed my TB IACV and cleaned my intake, hopping for the best.
