Interchangeable R4!

[mfg]

Can anyone name two components of the engine oiling system in common and interchangeable  between the 1964 Studebaker ‘Skybolt Six’, and the ‘64 Studebaker Avanti R4 engines ?

Air filter, and oil filter.

With you on the oil filter… not sure on air filter, as I see different part numbers…

Actually though, I was looking for two other items…. any other thoughts?

Are the valve seals the same?

Good question!… I’d guess they are… and I’d say they could be considered part of the “engine oiling system”

Not really what I’m looking for though!

HINT…. Let’s add some oil!!!!

Rocker arms, breather caps, oil pump gears although none of those are R4 specific.

Yes!… I had the R3/R4 and Skybolt Six oil breather cap as they are all of a larger diameter than regular V8…..

Not sure on interchange of rocker arms or the oil pump gears… but I’ll take your word for it!

Are you looking for specific to R4 not R3 to six cylinder?

Either one……R4 was mentioned in question…. but R3 and R4 engines would share the  same larger diameter oil breather caps, as used on the six (chromed of course)……True?

All 1964 Skybolt 6s had a breather cap intended for use with the mandated PCV system, i.e., with only two very small holes for pulling air IN.  Probably most R3 and R4 engines had no PCV system, and so their breather caps were open.  So, only the R3 & R4 engines with a PCV system would use a 1963-64 6-cylinder breather cap.

AFAIK only the 1961-62 non-california Skybolt 6-cylinder engines had open breather caps.  Those are the ones to look for at swap meets to chrome plate for an R3/R4 engine.

Good, interesting info!!

To clarify beyond Dwight’s great explanation, the R3 and R4 engine breathers when installed on a California or New York delivered R3 or R4 equipped Studebaker would have the early style 6 cylinder caps with all the vent holes silver soldered shut on both valve covers.

So, are we still missing one more part used on both 6 cyl and R3 R4 engine?

Silver solder job.. Wow!.. Talk about ‘hand built’ !!!

And yes… there’s a very important component that still hasn’t been mentioned!

Any other thoughts on this one?

Nothing yet?

HINT…. Do all the oil changes you want, but you’re R4 or Skybolt Sox won’t get very far without this part!!!
