Eventually, if this gets bad enough, it can cause a rough running condition and a misfire. There's oil now in the spark plug openings. After removing the coil pack, you can see that part of the valve cover gasket that goes around the spark plug opening has begun to leak. You might have to wiggle it because there is a seal in here. Use a ratchet extension and 10-millimeter socket to remove this 10-millimeter bolt. This procedure will be the same for the other three. Push down on the lock and remove the connector. We need to disconnect the electrical connectors and then remove the 10-millimeter bolts that are holding them into the head. It spilled underneath the oil fill cap, but the majority of this oil is coming from a failed gasket because you can see the seam between the valve cover and the engine head. There is some oil that's been spilled from when the oil has been added to the engine. It keeps the noise down from the valve train. They are 10-millimeter, so I'm using a 10-millimeter socket ratchet and extension. We're going to remove these two top nuts that hold on the appearance cover. This one is leaking quite badly, so it needs to be changed. Worst case scenario, if this is really leaking badly, you could cause a fire.

The valve cover gaskets are typically near the exhaust manifold. It will give you a rough running and misfire. There could be oil leaking down into the spark plug openings and then leaking past the spark plugs. Also, if you've got a rough running or engine misfire, the valve cover gasket also seals around where the spark plugs go into the engine. If you're checking the oil regularly and the engine oil keeps going low, it could be leaking from the valve cover gasket. However, some other things that would be a problem attributed to a leaking valve cover gasket would be oil loss. This is the number one easiest way to tell that you need a valve cover gasket. Because oil is sticky, dirt and debris will stick to it. When this gasket fails, you'll get a bunch of oily residue leaking out. Where that meets the top of the engine's head, there is a gasket that seals and holds in the oil.
