I have a 1997 Blazer 4*4 166k miles on it. I noticed it was leaking something under it. It smells kind of like coolant however it has a oily feeling to it. as I was looking under it it appears that is leaking oil on the drives side just under the coolant botte or so my oil appears to full and the coolant is full as well as the tranny fluid is full what could be leaking I had the intake replaced in 2011 due to a small coolant leak so is it possible that that could be leaking agian?

 

ok now thinking maybe oil leak just had the oil line oil cooler lines replaced on it too back in 2011 could it be those? Would the manifold be leaking oil? I had the lower intake man replaced in 2011 as well around April/May.

 

Its realy hard to tell from your pic but if its leaking from where the engine an trans is under the bottom couldbe the oil seal,It also could be leaking from either valve cover on the back or side then dripping down.If your oil lines were replaced it could be the where it connects to the bottom side of the engine.
