1967 327 oil filter adapter

[John Brown]

The K157 AC had you put the bypass valve under the new casting. Never had the Wix one, but the pictures of it look nearly the same. I never knew they had a paper gasket under the bypass valve when I worked in gas station changing oil. Mostly we never removed the bypass piece. We had a K-D tool made especially for digging the old square cut o-ring out. There were a few times when the previous filter change guy didn't remove the old gasket and we had to remove two (or more) of them.
