hmmm.... perhaps I am missing something here. My last post was concerned with getting the old, lower part of the oil line out from the water hacket. You wrote about fittings and such - I may be missing something in your post. The oil pump is in the oil sump and the oil line has to go through the cylinder block water jacket without causing a water leak. So, there must also be a water-tight fitting on the 'bottom' side of the water jacket that receives the oil line from the pump and conveys it into the water jacket. Then, of course there is the water-tight fitting on the outside of the block where the oil line comes out of the block (water jacket) and up to the rockers.
I was trying to visualize the process of getting the old, ruined oil line from inside the water jacket and putting a new one in. I suppose it will be obvious when I get the oil pan off again and look for what needs to be done. It's probable that one can not reach one's hand inside the water jacket to place the new lower part of the oil line where it is supposed to be, so there might be some 'threading' that has to be done, which may be easier with two people instead of just one.
