Oil on plugs 3 and 4

[nrmskate]

Okay, before we start, this is on my honda which is my DD. I just changed the valve cover gasket and afterwards, I let it run for a while and no leaks appeared. But the next day I drive it 10 miles and my mom said I had oil on the floor. So I look for a leak, no luck, so I look at the plugs, and cyl. 3 & 4 plugs where covered in oil. Could it just be the valve cover gasket? Maybe I need to take it off and reposition it a little bit? It didn't do this until after I changed the gasket.

Thanks.

idk about honda's, but did you replace the spark plug well gaskets (i dont know what it's actually called)? they're usually just big o-rings.

[nrmskate]

No, they didn't seem to be leaking so I didn't mess with it, but the only this I changed was the valve cover bushings and the gasket, thats it.

ok, I'd try to give it another shot if they werent filling up with oil before you replaced it, obviously you did something wrong.

I don't know which Honda you have, but most of them have spark plug hole gaskets. The valve cover go around the perimeter of the valve cover, and the spark plug hole gaskets seal off the spark plug holes.

There could be many problems: improper torquing, bad spark plug hole gaskets, malalignment of the valve cover, oil coming out of the spark plug thread (rare).

Check all of those.

Well, they are now.

lol, Thanks.

But yeah, the gaskets for the plugs I left. I torqued it properly, but my dad mentioned something about torquing certain bolts at different times.

its the spark plug gaskets, trust me

[nrmskate]

I take it I can't use gasket maker on them.

Damn, aight, well, does like AutoZone sell them?

[S14DB]

Even if they seal properly. You still have a good chance of gaskets failing as you take the parts apart.

[nrmskate]

^ I don't understand, Im replacing all gaskets.

I have everything apart now, im going tomorrow to buy new gaskets and reassemble.

its not the gaskets, its your torquing pattern.

I have plug oring gaskets that are fried and melted, and it doesnt leak a spec of oil, in any of my hondas.

But you can warp the aluminum threads with anything over 7lbs of torque, thus a horrible seal.
