Does the 2.7L have (air Jet Valves)inside valve covers? on 2003 Hyundai Santa Fe

Misfire on #5 after clearing fault code and adding Seafoam injector cleaner to tank. Kicking in passing gear causes rear blue oil smoke and code set again for misfire #5. Mitsubishi 2.8 is like that and when one went bad it would smoke the same as this 2.7L eng. Thanks,bob.
