Oil around spark plug threads
I changed spark plug on 97 accord SE with 184000 miles on it. I saw some oil aroud the threads and around the tip. Is that common to have the oil in that area. I read lots of forums about having oil around spark plug wires. I checked the wires and had no oil on them. Just curious.

RE: Oil around spark plug threads
On a number of occasions I've seen trace amounts of oil around the spark plug threads but if there is enough that the socket has oil on it when you remove the spark plug (like there is a small "pool" around it) then it might be your spark plug tube seals and there is a write up for that in our DIY section

small qunatity of oil is totaly fine... just maby a drop or 2... if it gets serious (teaspoon or so in the tube) then it can heat up and expand poping ur plug wire off.... and create a missfire... its realy easy fix, just a valve cover gasket set and a few tools... also a haynes manual is good

Thanks to all of you, just question, you guys talking about 4 upper tube seal gasket right not the lower ones (hard to do as it say in DIY section) Please correct me if I am wrong.

there are seal below the rocker arm assembly that if they leak, oil will go into the spark plug tubes ,,,,,
also like you said ( a small quantity of oil is totally fine ) , Wrong my friend ,,, there should be no oil in the spark plug tubes ,,if there is ,, than either the upper seals ( below valve cover ) or lower rocker arm seals are starting to leak and will only get worse with time ..

RE: Oil around spark plug threads
just always have had a TINY ammount when i say tiny... i mean like less than a drop...i dont tear apart my engine much 
but i know how my old SOHC engine was built (mitsubishi 2.5L) anyway... i dident have lower seals on that enigne... was just a single tube coming off the top of the cylinder head... anyway most of the leaking will start at the top one... again get a head gasket kit will have everything u need...
