I just purchased a new LO206 motor. The previous one was an early version that I purchased used with my chassis and used for 4 races this year. Out of curiousity, I went ahead and pulled the head on the old motor. From what I saw, carbon buildup to the outer edge of the head gasket in one quadrant, it appears I had a leaking head gasket. I am curious as to how much and in what way that woudl affect engine performance, and what difference can I expect with the new motor once I get it out on the track.
