Hello. In the picture, see the cover with the slot-head screws, below the exhaust pipe and above the braided oil line? What is that cover / what's behind it? The Assembly Manual doesn't speak to it, that I can find. This is a 1951 216 straight-6.
Any chance that braided line runs to a port on the middle top of the head on the distributor side of the engine? (a "cob job" way of getting oil to rocker arms).
Tim, that braided line is the outlet of the bypass oil filter that I presume is an add-on (not factory). I think it just runs back to the oil pan (if I understand your question correctly).

I know that there is a plug in the head on the right side of short side cover 235s where one can do the coronary oil bypass procedure, but can it also be done on a tall covered 216? Seems like the side cover goes up under the valve cover on the right side, covering the plug (if it has one?). Carl

I think you are correct, Carl (regarding short side covers on 1954 and later 235/261 "short" side covers).
I have never seen that external cob-job oil line from the manifold side of the engine to the distributor side of the engine (and, I cannot find instructions).
I don't think that would be a good idea on a spray-oiler engine, since the main purpose of the oil distributor is to restrict oil flow to the head until there's at least 15 pounds of oil pressure to the lower end of the engine. If something gets oil-starved, the engineers preferred that the rocker arms be sacrificed, rather than the rod, main, and cam bearings! Jerry

Attached below is the "after market" rocker arm oiler that will only work on heads that allow access to plug in the upper middle of the head (at the middle of the rocker arm assembly). I gets the oil feed from a by-pass oil filter T-fitting.

Good find Tim. The '53-'60 time frame corresponds with the advent of the full pressure 235 introduced in 1953 in Powerglide equipped cars. I have one of those and there is the plug in the head.

That 1953 engine is a rare "oddball" engine. Give it great care (as if I have to say that).
I hope your engine does not need that "snake oil" fixture, Carl (but if it does, it would be a good conversation/BS assembly).
The '53 with Powerglide 235 is pretty much the same as the '54 truck engine. The differences I have found are: They have Captains bars above the starter. The back of the crank shaft was not machined to receive a standard pilot bearing. (A pain.) They came with the 216 style valve cover. (Really cool.) They came with aluminum pistons and hydraulic lifters.

That 53 Powerglide 235 engine came with hydraulic lifters and the 54 truck 235 engine had mechanical lifters, and, presumably, they had different cams?
The 53 Powerglide engine came with the older 2 bolt valve cover (used on all 216s and on 53 and on earlier 235s), and the 54 235 engine had the newer 4 screw valve cover.
The vacuum advance on a car 235 might have a different angle than unit used on the 54 truck 235?
