serious engine problem

i have a 97 z24 cavlaier and it keeps blowing off oil caps theres a large amount of pressure coming out of the motor and it smells sweet my guess is piston rings but im not burning oil im lost?

i would look up everything that has to do with releasing pressure dude....it wouldnt be the rings cuz if it was the rings you would only loose pressure....or maybe your running too much oil lol

probably a faulty oil caps..
