oil leaking on your spark plugs in your Lincoln LS because you have a leaking valve cover gasket.
That is the correct spelling of "leaking" (losing fluid or pressure).
If air is leaking out, obviously the pressure will decrease to nothing. Find the leak and fix it.
yes because if the valves covers are leaking what is there to contain the pressure inside the cylinder
It's the coolant control valve for the heater core that's leaking. It's under more pressure when the engine is running and that why the leak is more noticable.
If it's leaking from INSIDE the firewall (away from the engine compartment) you probably have a leaking heater control valve or damaged heater core.
It may have a leaking head gasket. Has the coolant level dropped and needed more antifreeze . If so check it with a pressure tester
