Default Oil in spark plug tube

http://ca.pg.photos.yahoo.com/ph/andrey_x/my_photos

I was changing spark plugs today and when I pulled the plug rubber boot, I saw oil(red colour on the picture) there on the bottom of the ring, between the outer and inner ring. Does this mean that I have gasket leak? No noticable oil consumption. Please give me your input.

maybe you didn't tighten the plug enough when you last changed them.

I do not think plugs were changed before me.

maybe they got loose or some oil was spilled in that area. I dont think there are very many ways other for oil to get in there if it doesn't come from outside or from within the cylinder head.

I am not sure about that. Also I forgot to mention that both of holes on the left side of the engine have same issue. Plugs on the right side of the engine are fine.

guess it could be the valve cover gasket although im not sure exactly how that fits together. I do know that on my old MR2 if the gasket wasn't set just right you could get some oil in the spark plug holes.

The valve cover gasket is leaking (specifically the spark plug tube seals).

What year/mileage car do you have? May be covered under powertrain warranty

If left alone the oil will eventually deteriorate the the rubber spark plug boot. The seals aren't hard to change though. Just pull the valvecover.

I think Canada's powertrain warranty may be a little different, but check to see if you are still under it. If so, it is a covered component under powertrain

It's 5 bolts per side to take them off, and then you need 10 bolt grommet seals, 4 spark plug tube seals, and two valve cover gaskets. You can easily do this in the car in under 2 hours, probably under an hour if you are familiar with tools.

Called the dealer last night, warranty expired this July I will perform this job on my own I guess. The only trouble I will have is torquing the bolts, I don't have the torque wrench, so I will have to use my hands. It's very crusial to tigthen them right.
