Grey coolant, leak, and oil around injector?

[JShe8918]

So i took my fender liners out to drain my coolant again and found oil on my motor. It is just below my injector. I am uploading photo's to my computer now of the oil. Also i am loosing coolant and checked the hoses for leaks so now i am leaning toward water pump or radiator. I quit using antifreeze because it started getting exensive putting in so much everyday and started using water. The water turns grey. No white smoke or anything. I am thinking a pin hole in the radiator maybe? The problem started after romping in a pond. Truck started overheating and leakign coolant then. I can fill it and after one night of just setting up i will have lost about 1/3 of my coolant on the ground. But then it holds that amount for weeksTruck has a slight lope and i don't think it is tuning. Slight meaning hardly any. I am going to check my balance rates and try and post up a log of them.

Thanks Jon

Any idea of the oil leak from the picture? I know nothing of injectors....

Maybe a bad injector copper washer/oring or the lower valve cover gasket leaking around the injector hole

It's not the copper, when they go bad you get carbon & soot build up around the injector bore. I would think just a valve cover leaking. You can't see water leaking from anything? You should be able to fill it up, run it till it's hot & has pressure, then see a leak. Dumb question, but your sure it's not going into the oil pan?
