Yeah, I think it might be what bluethirtyfour said, whoever did the change last probably put some on the threads. Just wanted to clarify theres no seals for the spark plug wells. Thanks for the help guys.

I thought of that as well, but the electrodes were clean. And it doesn't consume oil.

Hey, Thanks for the reply. The oil was wet for the most part. I installed new plugs, and started the car to check if the misfire had gone, was still there. I wanted to check on the new plugs, and they were also coated in oil. Though, not as bad, being they were fresh. Is that so? Never heard of that lol.

Hey all, So I've been experiencing an intermittent misfire with my gtr r32, at Idle its not running on all cylinders. At some times it runs flawlessly. So my first thought was to check ignition, and to change out the plugs, as they haven't been done in a while. As I took out all the plugs, each of them was covered in oil, on the threaded bit only. The porcelain, and the electrode were clean and dry. So, my question is: what could be causing a leak down in the plug wells? Normally, I'd think of valve cover gasket, but it seemed dry and sits higher than the plug wells down in the valley. I checked everywhere on the net for some kind of replacement part seal or gasket, or tube that would fit in or around the spark plug well, but it seems its non existent? Also, I performed a resistance test on the coils which all read about 1.2 ohms, this is outside of nissans required spec (0.6-0.9ohms), does this mean they're on their way out? Any help is greatly appreciated. Thank you.
