HELP! I have discovered a port into each cylinders from the valve side of the engine. Currently they are soldered closed. What is their purpose and should I reopen these ports. Thanks, Bill G.

A picture would be belpful. Perhaps what you are seeing is the remains of the cylinder oiling system which someone disabled and removed. The concept was to provide a bit of oil to the cylinder walls just prior to choking and start-up. It was eliminated in later production as unnecessary. For authenticity you might want to reinstall the missing components just for appearances sake, otherwise leave it as is.

Thanks for the clarification. Obviously it is not critical to performance. Will I help gas washing cylinder wall by re-opening these orifices? I appreciate your knowledge!

Simply opening the passages will not accomplish what you want. For that you will have to find and reinstall all the missing component parts.

The oil priming on choke is on the left side. Those holes on the camshaft side (right) are little mister holes that align with the slot in the skirt. I don't know why anybody would block them off except if they want stuck valves.

There are a lot of things people are doing to those cars that make me want to throw up. Even the "experts".

G'day Bill Goodman,
to PackardInfo.

I invite you to include your '26 236 Packard in the Packard Vehicle Registry.

Tim, Thanks so much for your insight. This makes me ask, should I drill out the soldered closed orifices? The first post said not. I am confused. I tend to agree that the opening are needed for oiling the valve cavity. Clarify please!

Could you post a few photos of these welded holes? That would certainly help clarify what they are and the guys could offer you better advice if the had a look at what you were dealing with.

I believe the OP said the holes were soldered, not welded.

Did the engine originally have a Skinner Oil Rectifier? I am not that familiar with the 236, but our 326s had the oil rectifier which had lines into the lower area of the cylinder and would suck oil out of the bottom ring groove. The theory was that the oil was contaminated with fuel residue. The oil was sucked into the grapefruit size can mounted on the exhaust manifold where it was cooked to separate the fuel from the oil.
I have attached a picture of our rectifier but ours is no longer connected to the cylinders.
