I have a '96 3.8 Windstar with 77,000 miles. Alas, I have coolant in the drain pan.First noticed when doing an oil change, had about a tablespoon full of coolant come out. Proceeded with oil change, ran engine for a few minutes, pulled oil plug and had about a quart of coolant come out Probably isn't the head gasket, from what I've investigated, no smoke, no misfires, no codes. So, could it be the intake manifold gasket or the timing cover gasket? Is there any way to tell without removing the manifold? Please help, otherwise, I'm using it for target practice !!
