I Started my car for the first time since my rebuild tonight. It ran ppperrrrrrrrfect for about 20 minutes then the CEL came on. Car made some werid sounds. I can't really explain it, it wasn't knocking or anything bad, maybe a little valve clatter. I had just clearanced my valves right before this too. Anyway the CEL was 72,73,74. Misfire in 2,3,4.

I just changed the 2nd and 3rd rings, by myself, with just a HELMS and a torque wrench so I might have f#%@#% up. I went step by step with the HELMS, anytime I had a problem I went on here or searched around untill I found it. I was thinking of recording the sound that it's making,it seems like it does it only when it's warm.
