99 Chevy Suburb leaking Coolant

I layed under the vehicle to see where the leak is coming from.Its a 99 Chevy Suburban 1500. When I pour coolant in the recovery tank I can hear it leaking out as I pour it in.

l have only driven the vehicle in the last 4 days about 2 or 3 blocks always early morning or aftersunset (when its cold outside) and the heating temp will be at the half way mark.

I have noticed a huge cloud coming from the muffler. Dont know if its the car being cold or something else.

When I checked the oil it looks to have water in it.

Help appreciated, thanks.

If you hear coolant leaking out when you pour it in the recovery tank you have to have either a crack in the tank or the hose from the tank to the radiator has to be leaking. Your other symptoms sound very much like a blown head gasket or leaking intake manifold. Your oil has a milky tan color to it? Normal to have some steam in the exhaust when first starting up, but it should go away when things are warmed up.

Yeah the oil is milky tan in color.It has about 110k on it.When I had it smogged the guy said my hose had a leak.

Oh and I had the water pump replaced in March of 08.

And the alternator changed 2 months ago. Are these vehicles normally lots of problems?

Thanks

Greetings

First thing I would look at would be the Intake manifold leaking
internally. It is possible you have a blown head gasket.
