    Odd. Can you explain what the problem is more specifically?

    Note, if that piston is not stuck, and you have used a ridge reamer, leave the problem piston for last, leave the crank in, and turn the crank to top dead center. Unbolt the rod cap, back the crank out of the way, and tap the piston out using a piece of hardwood to drive with the rod. The rod will fit through the bore.

    We have all the other pistons removed. I took a picture of the rod, but it is hard to see. The rod does not fit through the bore. I am sending the block to the machine shop with the crank in. He wanted one piston, so I figured he could drop the piston out from below when he took out the crank shaft.

    Frank

    Frank, Welcome back. Two years!

    I finished mine, cracked a cylinder, tore the engine down, sleeved the cyl, reassembled and have driven a couple thousand. Where ya been?. Just yanking your chain.

    I cannot tell from the picture, but bet the rod cap bolts have become turned . That would indeed cause it to be bigger than the bore. I just checked one in the garage.

    Good luck
    Ben

    Sometime life gets busy
    The block is at the machine shop. I decided to have them assemble the bottom end. The owner is a friend, so it may be there a while. You know how that goes.
    His shop is extremely well equipped, and there is a lot of gray hair that is familiar with straight eights.
    I am going to attempt a re-wiring of the car, and clean up the engine bay (finish some front suspension work) while the engine is out.
    The wish list is bigger than the wallet

    Rod too big?

    Obviously they removed the rod. Can you tell us what was wrong?
