So my valve cover gasket is leaking oil onto the engine and down into the spark plug wells so I need to get it fixed. I want to order a new valve cover online but I am a bit confused because some of them I see o-rings included in the pictures and some I don't.
1) Do I need these o-ring? What are they for?
2) If they are needed, are they just a standard O-ring that I can pick up separately?
Hopefully someone who has done the replacement before can let me know.
Thanks!
