Toluene Dart - '73 swinger
Well, last track day kinda sucked.. Apr 27, one of the intake rockers seized on the shaft and held the valve open. Mr. Piston decided to say hi. Didn't realize what had happened, as the sound it made almost sounded like a burnt plug wire or bad spark plug. Up until I got it back to the pits and really heard it. The carnage wasn't all that bad, almost no noticeable damage to the piston. I guess my modified oil bolt on this side didn't get drilled large enough. So I fixed that issue.
Found someone in town selling a brand new set of Harland Sharp Rockers for $400. Found a new Edelbrock intake valve on Amazon for $6, measured for new pushrods and bought some chromoly pushrods from Summit. Tore everything down and pulled the oil pan to make sure no more surprises inside. Everything looked Good in the oil pump and bearings, I got lucky. Got the rest of my parts saturday afternoon.. engine back together and fired by midnight. Honestly I think the rocker was having some issues the whole time, because it idles much smoother now.
I have a video of the carnage pass.. it sounds pretty normal, I believe the failure happened pretty early in the run. Probably around the 40second mark in the video.
