I was given a 1989 Devile 4.5 fwd I drove it home a few houses down the road with no problems. I left the car running and got out to do a walk around and I noticed there was water coming from the exhaust. My first thought was a blown head gasket but I've never worked with a caddy before I know some GM cars run coolant threw the throtle body. Any thoughts or ideas will help thanks.

I am not 100% sure, but the 4.5's intake manifold gaskets were not as prone to leaking as the 4.1 (HT4100), if that is what you are thinking about

KHE (Kevin) is knowledgeable about these engines, I am sure he will provide his knowledge

The 4.1/4.5/4.9 engines are not known for head gasket failures. If you are not going through coolant and not overheating, it is most likely condensation.
