Do they smell like gas? Back oxygen sensor. Bad MAP/MAF/IAC. Were they properly gapped?

Yes, they are all properly gap. I think it's oil covering the plug tip and electrode. Not that smelling gas but unburned oil from chamber instead. Where were probably the oil coming from. Is there any possibility of broken valve seal or piston ring causing this problem? Thanks

Yep. Leaking valve seal. Leaking rings. Or blown head gasket.
