i just swapped my old spark plugs today for denso and found oil on the washers of the original spark plugs. the old plugs look good however so i'm not sure what to make of it. for those who replaced their spark plugs, did you guys see oil and it this common?

thanks,

How much oil? A light coat or more?

Fish - has your v/c ever been off? There are seals b/w the v/c and head - if these dont mate, you could end up w/ oil on the washers. Usually though, it isnt all four. If the electrode and threads are clean - I won't sweat it.

 

If the #4 plug is very oily then you need to see your dealer. A little amount of oil is normal if it's even between the plugs.

 

from what i can remember, the oil was on #2 and #3 plugs and it was a very little amount. the reason why i am slightly paranoid is that i have been hearing a faint fluttering sound coming from my engine when i slowly accelerate between 2000 and 3500 rpm. i'm not sure if this is normal engine wear or the dreaded #4 cylinder problem some of our fellow s2k owners have experienced. i hope it's not the latter. anyhow, thanks for the insightful replies. - fish

 

Not always a big deal. I had oil on the washers of #4 but mostly because the oil filler cap rattled off and oil was splashed around.
