Check the usual suspects. Head gasket, freeze plugs, galley plugs and what not. Get a tester to check your cooling system pressure and see if there's oil mixed in

 

Deja Vu?

 

when you have antifreese coming out the tail pipe(whitesmoke, usually a sweet smell). I can only be 2 things a bad headgasket or a cracked head. Now I highly doubt that you cracked a cast iron chevy head. and I've never see someone crack a block, unless the car war ran without oil, raced to the limits, or had pure water as coolant during the winter

First take the heads off, have them pressure checked and milled, then get some nice copper head gaskets from summit or jegs

 

On a Jeep strait 6 it can be 3.... the intake manifold gasket can also allow water into the intake manifold.... just thought I would add that!

 

The first thing you do to determin if you have a blow head gaket or crack head/block ..is to see if the coolant is mixing with the oil....If it a Milky chocolate color then you have problems...[QUOTE]





SoRRoW- it IS a milky chocolate color, so what do I do? Could it still be a gasket? or am I just screwed?
