I have radiator fluid dripping directly from the Driver's side exhaust manifold. Do you think it could just be a bad head gasket or is it a cracked head?

Are you sure it's coming from the head and not a hose or other gasket? The throttle body preheater is up there and it leaks down onto the valve covers...

A bolt snapped on that exhaust manifold were it meets the Y-Pipe so it is loose and leaks.
The radiator fluid was bubbling out of the leak and it looked to me that it was leaking straight from that spot. Also the exhaust was very thick and whitish looking. The car was at operating temperature.
Also the throttle body looked dry and there wasn't any moisture above exhaust manifold.
EDIT:
Ok, I double checked. It is for sure coming out of the exhaust manifold on driver's side. BUT, I did see radiator fluid on top of the Valve Covers. The lines from the Throttle Body do not appear to be leaking. Not at idle anyways. Also water definitely seems to be gettinginto the oil. I checked the dip stick and the oil has turned milky looking.
To answer your question, it could be either or both, you won't know till the heads are removed and inspected. Odds are with you that it will be only the head gasket.

Pull the spark plugs and you will tell what cylinder is sucking water by the look of the plug. that is, the bad one will be steamed cleaned. If it is one of the rear two cylinders, there is a good chance it is a head gasket, any of the other 6 and it is more likely a slipped liner.
@brian4d: 140,000 plus miles, it can't be driven without overheating.
Thanks for the info. I'm setting up to pull the heads and take a look. I have a lot of bad seals anyways. Oil is coming from everywhere. I'll probably change out most of the seals and anything else important like the timing chain while I'm at it.
I priced out some new heads on Atlantic British if I need them.

Problems is this. If it's overheated to the point the alum. block expands thus expanding the sleeves you're going to have a problem... If you've overheated multiple times your chance of have a bad liner (sleeve) is going to be higher. It's my understanding you can do a pressure test on the block to look for a slipped liner.
Should you be lucky in your bad luck and find that it is a bad head gasket, get the composite kit from AB which is much better than the OEM one cause it is coated and protected to avoid being affected by the dexcool coolant like your stock gaskets were.

Also buy their new head bolts and if you haven't replaced your upper radiator hose with the new one that has the bleed screw located in the "T" then get that along with a new t/stat.

Cylinders 3 & 7 had radiator fluid in them. #7 was the worst and was very clean and filled with fluid. At first inspection the Head looks good, but when I clean it up I'll know for sure.
Also the lower manifold gasket on the underside of the gasketonly, there were broken off chunks by #7. It's like a thin layer of coating was coming off just on the under side.
The passenger side gasket was even worse. Anyways I'm thinking about doing the cylinder head overhaul myself.
I've never actually did it, but it's pretty straight forward and I have all the specs to see if anything is stretched. It's either that or take it into a machine shop and have them do it.
From what I have read and heard, there usually isn't a problem with the Valve Springs or Valve Stems.
Has anybody ever had problems with them before and had to change? There is about 150,000 miles on the vehicle.

Head Gasket or Cracked Head?
