i don't mean to change the subject but, i've also been tricked int swapping out a 216 in a 51 flatbed. this engine isn't getting oil to the rocker arms. in fact there is no tube connected to the rocker shaft oiler thing. when i pull the side cover i see an open hole going into the water jacket, and if i look through the hole diagonally i can see through a hole in the other side of the engine (like a block drain). so my question is how does oil get to the top? there is an oil pressure port on the d/s, so i assume you run a pipe from that through the holes in the water jacket and up to the rocker shaft? but how would i seal around where the pipes go through the water? all the help would be appreciated, i'm only 21 and this is the first 216 i've ever seen. matt
