View Full Version : Crankcase Venting for a 289

What is normally used to vent the crankcase on a '63 289? The Chassis Manual, on page 13, shows an adapter that attaches to the valley cover that is then attached to what I am 'assuming' to be a PCV valve then into a 90 deg elbow in into the base of the carb. A 2bbl is shown in the manual, is this setup the same for the 4bbl? I cannot find these parts online, where are they available?
By the way anyone know what kind of coating Studebaker put on their new short blocks back in the day? I tore mine down and not a spec of rust anywhere on the block after sitting in a crate for 43 years, and it cleaned up with carb cleaner!

There was a tube inserted in the base of the carb that the breather inserted onto. The other plumbing is entirely correct. As to where to get one? Beats me. The carbs either seem to come with one or not. I may be out in left field, but... I think those setups were for California emissions.

The 4 barrel uses a screw in PCV valve and was stock on all 63 Studebakers.

The R1 with the AFB carb used a screw in PCV at the base of the carb. These are available from NAPA. The number is 29267.

Well, I am trying to adapt as many parts as possible from a '61 partial flow engine to the '63 full flow short block that I have on hand. I have no idea on the original setup, the 1961 Hawk came with an empty engine compartment, a '63 short block in the crate and a shop full of Ford and Stude engine parts that I have sorted through. My WCFB 4bbl does have a pipe plug in the base. I guess the part I really need is the piece that attaches to the valley cover. I will check NAPA for their valve.

I believe your engine was coated with Cosmolene, which has been around for something like 100 years. It's a petrochemical that falls somewhere between heavy grease and asphalt on the molecular scale. It's absolutely waterproof, but is soluble in gasolene, kerosene, and most other lightweight hydrocarbons. It was widely used to protect weapons and other equipment being shipped or stored during WWII. After the War, the gov't sold off much of this stuff as surplus. There were many stories of crated Jeeps, coated in Cosmolene, that could be bought for $100.

The '61 Hawk most likely would have had a draft tube instead of a PCV valve. :D
