Yuck!   I was out messing around and I did a full nitrous run.  I felt the engine studder a little in 2nd gear so I shifted to 3rd and hit it again, same result.  Then BOOM dropped a cylinder.  I immediately shut off the engine and drifted to the stop.  Got out and looked the engine over, I didn't see any oil or damage so I tried to start it.  It started and ran on 3 cylinders, so I drove to the shop, pulled the plugs and did a compression test. Well, found the problem as shown below.
