My s14 started smoking BADworse then ive ever seen

but its not knocking or making any abnormal sound

i was thinking it was either piston rings, a head gasket, or valve sealsmaybe a pvc valve

but before i pull the engine out can anyone help me out if they have dealt with the same thing

Bad injector, too much fuel...... wouldn't run great, but maybe runs ok?
