I noticed some hesitation in my 94 525i, so I decided to pull a plug and have a look. When I removed the #1 coil pack, I saw a decent amount of oil pooled up in the bottom of the hole. It looks to me like this is coming from the rubber seal near the top of the recess for the spark plug. I'm guessing this is the valve cover gasket. Has anyone had a similar experience? The gasket job doesn't look to daunting. That's one of the things I love about a straight 6 motor. Things are generally very accessible.
