it could be coming from a valve cover gasket that is leaking
Most common cause for a misfire on the 2.5L is oil in the spark plug holes do to leaking valve cover plug tube seals. You would need to replace plugs, wires, and valve cover gaskets in that situation.Most common cause for a misfire on the 2.5L is oil in the spark plug holes do to leaking valve cover plug tube seals.

Depending on the engine, it could be a leaking valve cover or head gasket.
only time you would need to replace valve covers,is if they are dented and allowing rockers to hit inside cover,or they have holes in em letting oil leak out. you may need to change valve cover gaskes as now and then they will leak oil
The seals inside the valve cover on top of the plug tubes have failed.
Please restate the question. What are you talking about? Valve cover gaskets, valve cover, what? need a valve cover
There are valve cover bolts around the perimeter of the valve cover. You want these tight but not as tight as you can get them.
As with all valve gaskets it is located between the valve cover and the head. To get to it you undo all bolts holding the valve cover on and then pull valve cover off. you will find it on the valve cover/ head contact point.
it is on the valve cover, usually in the driver side valve cover. If you have a 2.2 L engine, it doesn't have a serviceable PCV valve, it is built into the valve cover.
# The PCV valve is located in the valve cover # Detach the hose from the valve then unscrew the valve from the valve cover
Remove the valve cover.....scrape off old gasket.....clean gasket surface on valve cover....apply gasket sealent to valve cover gasket surface.....set gasket in sealent.....reinstall valve cover.
remove valve cover, get a piece of cardboard or something to block the oil from spitting everywhere, cover the oil holes with the cardboard, start engine, loosen rocker arm nut until it ticks, tighten SLOWLY until ticks stops, repeat for every rocker arm nut, stop engine, replace valve cover
