The spring was done away with 1957 I think.gtx469 wrote:I see a lot of posts saying that there is a spring in the flapper valve crank nut breather. I just did the oil seal mod to my 61 G9 and my crank breather nut does not have a spring in it, just a small stainless steel plate held in by a peened edge ring. seems to work just fine blowing air out to case but seals going in. Is this nut something that was changed in 61 era?
