When you buy the valve cover set, it will include the spark plug well "O" rings. Simply remove the valve cover and on the underside of the valve cover, you'll see the "O" rings that need replaced and you'll see exactly how the valve cover gasket itself fits.

Oil in most of my spark plug ports!


The fault is due to the valve cover gasket passing oil into the spark plug wells. There are circular seals under the valve cover around each spark plug well opening. These spark plug well seals come with the valve cover gasket set.

Why does my 1997 honda accord have oil around the spark plugs?


You have to replace the Valve cover gasket. Inside the spark plug hole, midway down is a gasket, every spark plug hole has them, you cant see it because its, well a gasket pressed against two very tight suface every spark plug hole, When these leak they fil up the sprkplug cavity, as you know. Go to a parts store, spend $30 dollars on a VALVE COVER GASKET SET. If reparied properly wiil be a 100% fix. If it's a 4 cylinder honda,, a monkey with downs syndrom could do this in five minutes. V6 accord, save yourself the time, grief and heart ache, and take it to a Professional.

Changed the spark plugs and the old ones were covered in oil


i'm guessing that your car is a 4-cylinder. this is common for inline 4-cylinder engines. since the spark plug holes usually go through the valve cover, the valve cover gasket will leak and collect in the spark plug holes. to fix this you will have to replace the valve cover gasket.

Spark plug well filling with oil.


a new valve cover gasket and o-rings around the wells should have cured this...did you clean the old o-rings off the valve cover completely before installing new ones? this is a common problem with these models.....i would re-check my gaskets and mateing surfaces. valve cover gaskets and spark plug well o-rings are relatively low cost. the spark plug is tight, correct? write back with an update!

Spark plugs


Who ever told you it was the Valve cover gaskets was correct. On the valve cover gasket around where the spark plug goes down though the head there is a seal made onto the valve cover gasket called the spark plug well seals. when replacing the valve cover gasket it will come with these seals and it will take care of your oil leaking into spark plug holes. Hope this has helped and if you need anymore assistance I would love to help.
