Warped spin-on oil filter adapter? y-block

[Sid]

You may also try taking a pick or something with a sharp point and running it in the area where the gasket went for the original canister. Just in case there is a small piece of the old gasket that was missed. Also I think the adapter has a top. Also before torquing down maybe try turning back and forth a few times to help the adapter seat. Worth a try...

After problems with two adapters, I went back to the stock unit and haven't had any problems since.

I think what he means there, is that the adaptor should be installed so that the little oval shaped hole is aimed toward the top, but if it were installed with that hole turned in a different direction, it will not cause a leak.

As I recall, the adaptor plate on my Y-block was made of pretty thick metal. My guess is that the new adaptors you can buy from the resto parts suppliers these days are probably much thinner metal and need to be dealt with carefully.

Additionally, I do not use an oil filter wrench to tighten the spin-on filter on mine. Just hand tighten. Coat the gasket on the back of the filter with oil before screwing on to the fitting. Mine does not leak a drop with hand tightening only. Just throwing that out there in case tightening the filter too much might be distorting the adaptor plate.

I used to have a 312 that would randomly push a bunch of oil past the gasket next to the block. Usually idling. I was young and dumb but I think it was a problem with the by-pass sticking.
I agree that anything newly manufactured would be suspect as not having original quality. I have a couple extra junk 292s with original spin ons. I've been going to put one on my 59 pickup but am balking at the price of the gasket,lol.
