I have stripped the engine from my 41 3/4 ton down to the block in preparation to bring it to the machine shop. I have two parts left to remove and am sorta stumped. First I have an oil line that runs through the block from the oil distributor to the other side of the block connecting to something if I remember right it goes up to the head. The other is the crank case ventilation tube. How does one go about remove these items? The only evident way to me at least for removing the copper tube is to cut it off and replace it. But I don't want to have to destroy anything if possible. Any advice help would be appreciated.

Thanks,

Dan
