The saga gets stranger. I pulled the oil pan and replaced the oil pump today. The only hole that goes through into the inside and would drain to the pan is the one I previously described that had a plug in it. The two threaded holes marked 1 and 2 on my photo do not go through into the oil gallery or into the interior of the block. To make matters stranger, I removed the rocker assemblies and checked the hole there for the oiler. It goes down about 2 inches and ends, so the only way I can see for oil to ever have gotten into the rockers is through the line that went around behind the engine and threaded into the hole near the coil on the opposite side of the head. Strangely, this threaded hole is drilled through to run right into a head bolt that sits inside the cylinder head. I tried shining light through to see if any gets past the bolt to the oiler hole and nope. Nothing there. I'm going to take a few more photos and send them to Oly in hopes he will post them so you can see what I'm dealing with. At this point, I can't see any way that there ever was an oil filter on this engine. The intake location at the gallery would have to have been for the intake on the filter, the exterior line that goes to the threaded hole on the other side forward of the coil and the oil pressure gauge. Can it be that a '60 235 for a car would not have had an oil filter even as original? Very strange indeed.
