I have been hearing this "boiling" noise coming from under the hood for a couple of months ago and have been told many things to replace, but I just don't have the money...so...

Ok, here is what I know and what observations I have made...

My oil is not white, there is no oil in my anti-freeze, so I am assuming this rules out a busted head gasket?

It only does it once the car has had time to heat up to normal running temperature...

It only does it when I press on the gas, when I take my foot off the gas, it stops!

I have no visible leaks, I am not having to add anti-freeze and/or water constantly...

Any ideas? I am basically trying to narrow it down to one thing or another because I am about to get married and I don't have money to be wasting on things that will not fix the problem...Thanks for anyone who replies!

The most accurate description of the noise would be to take a straw and put it in a glass of liquid and blow into the straw, that is what it sounds like...

What Kinda truck do you have. You should check your coolant overflow container and see if that is what is making the boiling. My old car did that and it turned out to be a leak (The head was warped) and I had to get a new head for it. Usually a leak in the cooling system can cause that problem. Beyond that there really isn't anything else that could boil or bubble like that, at least I can't think of anything..
