Need help with spark plug tube seals I just had my valve cover gasket changed by a friend, and he said that there was oil in two of the spark plug wells and that the seals were damaged and i should have them replaced. My question(s) is, do i need to buy seals for the upper or lower seals? Would Everything that came off replacing the valve cover gasket need to come off again in order to replace the spark plug seals?

Yes you will have to remove the valve cover in order to replace those seals. There are only the one set and they sit inside the valve cover.

Re: Need help with spark plug tube seals
They are not thumb-press-fit seals, either. Their tension is very much like oil seals for cranks and transmissions and such: a steel collar molded into the rubber seal.
When I swapped my heavily-leaking VC gasket set, the seals were pretty tough to get off AND on, even with a seal puller and some normally-successful install tools (I wish Honda put that kind of engineering margin into the rest of the car). :P
Be careful esp during install... and when you have them in, remember that when the spark tubes poke through them, that the downward-facing seal can flip up and potentially leak (needs to be this way due to crankcase pressure -- if they faced the other way, blowby would push out the seal and into the plug well). Work the tubes into the seals, then work the cover and edge gasket down onto the head. Not as difficult as it reads.

If you think a good mechanic is expensive, try hiring a bad one
Re: Need help with spark plug tube seals
Be careful with reinstalling the valve cover, those rings can get hung up on the tubes.
Yeah, that.
