New problem developed today as I am on vacation 300 miles from home.

I have a constant chripping noise from under the hood that increases with rpm (all new pullys were replaced less than 10,000 miles ago) and there is also antifreeze around the valve cover on the drivers side :-(

 

The coolant on the drivers side valve cover is probably coming from the gasket at the throttle body heater plate. As for the chirping noise I have no clue.

 

I should have noted I have replaced the gasket at the throttle body a few months ago everything in that area is dry this leak is back towards the firewall

 

The chirping is typical of accessory bearings going bad. Likely your alternator or AC compressor clutch. Probably the alternator.

And I agree with the TB heater as the likely cause of coolant in that area.

EDIT: No, I don't. You must have posted the above while I was typing this. No way is it the TB heater if its in the back.

Making it 300 miles? I'd say the accessory chirping is no big deal. Losing coolant is another matter entirely. How much are you losing? If its not much, you might get away with it. But without knowing exactly what's wrong, everyone here can only guess.

 

Head gasket or intake manifold gasket. Coolant leaks located at the back of the engine are common on Land Rovers and never good.

 

What's the odds this thing can do a three hundred mile trip home

 

How bad is the leak, is the oil a milky color, how low on coolant is the coolant reservoir tank, do you have to top it of often, and when did you notice the leak?

 

Pretty good, just keep the cooling system full of water, collect some empty milk jugs, washer solvent bottles, etc.
Fill them with tap water and keep them in the truck, top off the system before you leave, every 100 miles or so stop and check the coolant level by looking through the side of the coolant overflow tank.
If it is full keep going, if not top it off with the water.
Dont waste your money buying coolant.
If you stop at gas stations you can get more water for your jugs if you need to.
Once you get back home you can get a better diagnosis and then fix what needs fixing.
I am assuming that this is a small leak.

On a side note this is the only time I would ever use a radiator stop leak, 98% of the time they do not work and they just clog your cooling system.

 

Thanks seems to be a really small leak at this point less than a quart in about one hour of driving and no milky oil I don't think at this point its leaking into the engine

 

300 miles isn't really that much. I would do what spike suggested and check the coolant level along he way. I hope everything turns out OK.
