Because you talk about an orange Fram filter, I'm not sure what you mean. I'm assuming you're using "Fram" as a generic term for oil filter. I'm also assuming the canister you refer to was painted; the metal on my '67 GTV was black when it came from the factory.

A disposable filter goes inside the canister and a rubber seal (o-ring) goes in the circular groove in the block, where the metal canister presses against. I have a 2L motor in the car now, but when the 1600 and 1750 were in it, I always bought filters several at a time from Centerline or IAP. The filters should come with new o-rings.

The rubber o-ring can be the problem if you don't get the old one out and you put a new one on top of it. I used an x-acto knife blade to pick out the old o-ring. You can't see the o-ring when the engine is in the car, but the x-acto blade made quick work of either getting out the o-ring or making sure it had fallen out when the canister came off.

It's also possible to twist the o-ring when installing it or to fasten down the canister so it's slightly off center. Both will cause leaks.

When you push the cannister on, you have to hold it up against the o-ring and housing as you tighten it down. You can feel around the edge of the canister once it's in, to make sure it is seated in the groove.

If you have an entirely different type of oil filter, just disregard the above and apply the old adage that to assume makes an *** out of ...
