Help with the headgasket

[SikSR20]

I have a 94 240 it is a coupe. Ok this is probably going to get the reponse of just buy a new engine. Ok I know for sure that I have a blown head gasket. As you know the car heats up very fast. So I figure that, that is the headgasket. So when I start it I have blue smoke and white smoke. I believe that the white smoke it from oil in the fuel line. The blue smoke I think is from the piston rings. So if the blue smoke is from the piston rings I would have to change those. Also everything I have driven it the radiator has been empty eventhough I have topped it off everytime. So I'm guess that the water going in because of head gasket.. I dont think it is a leak because I have not seem any water or oil spots under my car. I checked all of the hoses and there is no water comming out of those. If i have maybe a cracked head how could I check for it and or know.So I am at a loss right now I'm not to entirely sure about what is wrong with my car. So if anyone has any ideas as what is wrong with it please give your advice it would be greatly appreciated. Also if I need to change the headgasket could you tell me a website that can show me how to properly remove and put together the headgasket and possibly the piston rings
Oh I also checked the dipstick for the oil and its practially water with a small hint of oil.
Also the whenever I rev up the engine the belts start to sqeak and to be honest it sounds like ****.
