I am having oil leak into my second spark plug. 1-2-3-4. I did a headgasket and valve cover gasket. Replaced the seals around the spark plugs. But I still have oil in my spark plug wire when I pull it out. I did some research and people were saying it would be the seals. I made sure that the spark plug is tight in place but I still am running into the same problem. Does anyone have any ideas? Thank you so much.

After further research I found the culprit!

Glad you figured it out. The D15B7 and B8 both had upper and lower plug tube seals. If you only replaced the upper, the lower (under the rocker arms) could still be leaking.

I'm sure you know this now. This is provided for any others who come across your thread via searching.

Cheers.

Hey I'm having same problem whoever I bought the car from 3 put of four plugs were not even connected I cleaned the oil out and now when I checked there is just a minimal amount of oil is this bad? What's the problem?

I'd clean up the outside of the motor and replace all the tube rings and the cam cover gasket while you are at it.... IT's the tube rings...

Is it bad. Well it will store heat around the spark plug and that's not exactly a good thing. IT won't kill you and you aren't losing oil pressure because of it. It's an inexpensive fix that just takes a little time, pretty simple really.

Which car? The motors differ between trim levels and generations (years). And even then, that's assuming you bought a Honda.

Okay, if the oil is coating the tube from the top all the way down then it's the ring seals on the valve cover (upper tube seal). If the tube is dry but there is oil in the bottom of the tube on top of the spark plug (plug wire tips are wet with oil) then it's the lower tube seal that is bad.

The lower seals require removing your rocker arm assembly to replace. One of them being a funky figure 8 seal.

If you need the FSM pages for it, just holler and I will post them up in this thread when I get home from work.

Was able to use this thread to help me start figuring out my girlfriends issue. 2009 Chevy Aveo and oil coming into spark plug area in cylinder #2. Thanks everyone.

Thanks man I plan on doing an engine swap in a 2 to 3 months this won't harm my engine will it?

I had oil on the bottom of the tubes for awhile and it didn't seem to affect mine any.

YMMV
