Finishing up replacing my spark plug tubes today and I noticed that there was dirt in one of the wells (with the tube removed). When I pulled the tube, there was a considerable amount of dirt on both the green and red o-rings. What concerns me is the dirt around the green o-ring. I peeked inside the well and sure enough, there is debris around that area. Is this cause for concern? I tried to snap a pic of the well and you can see the dirt hanging around the area that the green o-ring would sit at.
