I broke a head gasket between the #6 & #7 cylinders, causing a misfire and before i knew what the problem was, i revved the motor and (only at high rpms) i could hear a loud clacking noise from what seemed like it was inside the motor. At that time, i assumed i broke an internal part like a rod or something, but i was able to drive the car a short distance home and pulled the heads, which is when i found that i broke the head gasket. Now, im worried that the clacking noise is still a broken part down below, so i dont want to just throw new gaskets on it and assemble it, for fear of grenading the motor. With the heads off, the cylinder walls and pistons look fine, other than some carbon build-up. With the distributor in the motor, i turned the crank with a socket to see the pistons go up and down. i turned it enough for the TDC piston to go from top to bottom and back to the top, twice. I was worried that i need to keep the engine rotation in line with the distributor, but now i want to pull the motor and have someone inspect it, and rebuild it if necessary. so im not sure if that matters? If the engine rotates seperate from the distributor, what will i need to do to get it back in sync? should i turn the motor until a specific piston is at TDC before removing the dizzy? sorry for the long post and thanks for any advice!
