Well, I overreved the 2.0L at the track a while back, and now have a strange vibration. Happened right after the overrev, idles fine, just does it when I rev it up or under power. Have taken the engine apart- heads, cylinders and pistons at the shop today, a cursory inspection hasn't revealed much, #6 piston has a mark where the valve barely grazed it, all the cylinders look good, as do the rings. Going to have the heads/valves tested to see if anything bent. I also heard over the weekend that I might have tweaked the clutch somehow? Any advice would be awesome!
