late flathead oiling?
I have a 1952 Canadian Mercury engine it came with the metal can oil filter mounted on the head, this has small 1/4" lines.
I wanted to change it to a modern spin-on oil filter with 3/8" lines but all the info I have been reading on this forum suggests I have to do machining on the block
which I don't want to do as the engine has already been rebuilt.
I recently read that very late ? Canadian blocks are already drilled and tapped
for the horizontal plug that goes between the oil pump delivery outlet and the return line that goes back into the block. So I tried a 7/16" fine thread set screw
screwed into the side of this fitting it was very tight so I tried sanding the threads on the set screw down and it fit all the way in to the area between the two vertical outlets. I have installed the filter fittings and am now ready to put
on a new filter, I have enclosed a picture what do you think ?
