Help!! I am smelling a coolant on my 90 Civic EF sedan like if it were leaking but I can not find were it is leaking. It seems to be coming from were the intake manifold is but when I check my hoses they all seem to be fine... When I get under my car I notice that there are water marks all over my cat converter.... Any advise on what i should check???

 

Could be leaking coolant out of the intake manifold gasket

 

I just had that replaced along when i had my head gasket redone... I'll double check though thank
