Head gasket

Hello. My car was loosing coolant I could not see it, just smelled it. Would have to add water about once a month to begin with. One day, I was caught in slow traffic, car went to red zone for about four minutes, pulled over let cool. Did this three times before getting home, only stayed in red, for a couple minutes, each time between cool downs. So yesterday, after the leak is worse, I discovered water dripping from bottom of radiator area. Been using straight water for about one month. So I know the radiator is bad. And, the radiator cooling fan has not worked in two months, but it has been winter time. No milky look on oil cap. Today I followed instructions with cap off, let car warm up and watched for bubbles per video. It would only one bubble about every thirty seconds at most. No stream of bubbles. Have not done any other tests yet. Now, when I know I need to add water, I pull over and carefully remove cap. As I add water, lots of air comes out of radiator, until I get a smooth flow of water in radiator. Always air, when I have to add water. I am getting new radiator, fan, and the right fluid tomorrow and not driving anywhere hardly until then because the car has always been taken car up, using no oil, with 282,000 miles. I have just recently let this slide, but now I am worried about the HG. But considering right now, I have a broken cooling fan, a leaky radiator, and using straight water, would you think this occasional bubble would be natural, under the circumstances? Or should I be worried about even one or two occasional bubbles every thirty seconds or so?

Thanks so much! Jerry
