Found these in a friends garage and he gave them to me but don't know what kind they are... I saw a picture of a flathead with similar breathers on the oil pan but I'm not sure, they look pretty big for valve covers. Thanks in advance Tom
Oh Tom those are junk you don't want those. Do ya still got my address? Look for some sort of markings on them. They look like the real deal hot rod chit my young friend.
They are Offenhauser's, they bolt to the side of the crankcase to breath the engine. Ive got 2 more --pm if anybodys interested
either crankcase sides or Buick nailhead V/C...nearly 90° - won't work on any other engine with canted valve covers dj
They are generic breathers that were cast in the 50s-60s and sold by just about everyone. Offenhausers were 2 piece units with the name cast into the cap but you could get a 2 piece breather with a generic no name cap and the parts interchanged. I didn't want the advertizing and used the smooth caps. Offy's say so. Your type were popular on HP flathead mills. When I first got into flatheads I though how cool they were on the pan and then an old timer said where else would they be on the valve covers?? Doh!
I agree. Some of those one piece types like yours are pretty big for valve covers. I've seen them on Himi VCs. on the ends. The 2 piece Offy style were available with 2 different angle bases. These are less than 90* I didn't care for the look. Too many angles for my eye so I replaced them with the 90* bases. They work great.
