coolant leak on beater...question

thats the problem. My camaro is in the heated garage…and im not taking it out because its apart…so I will hafto do this in my driveway…

It might be as simple as a bad radiator cap is what im thinking…it seems to be pissing out somewhere ontop and getting everything below and around it wet.

bad radiator caps show their weakness when theirs a load on the engine?? (in drive) because I dont see a damn thing leaking at idle.
