Got my new oil filter yesterday in the mail, and will change oil this week.
Is it necessary to change out the oil filters "O" ring every time?

I guess we are talking the oil canister here ??
Boy, I'd sure change that "O" ring each time and you need to take a strong flashlight and make damn sure you get the old one out in tact....if you don't it can cause some serious grief..

Yes.

You might get away with not doing it a few times, but it will eventually be a problem. Some folks in the past have left the old one in place and installed a new one on top of it. Again, an accident just waiting to happen.

I use a very thin jewelers type screwdriver to get behind the old gasket and pry/lift it out. Very quick and easy. Others remove the two screws that hold in the oil bypass valve and remove that valve. The o-ring then falls out into your hand.

I use grease or Vaseline to hold the new o-ring in place when installing the filter. Clean the oil can. Then refill the oil can with a new filter and a quart of oil. Install and torque the holding bolt to 20-25 ft-lbs. Then start the car and check for leaks.

is there any reason not to change it? New one comes with the filter.
just stick a long needle into the crevice and into the old gasket, and pull it out, or pull both out if there are two stacked in there.

Absolutely change it out each time unless you like oil on your garage floor.

Also why would you have to mail order one?? I know most places don't stock them anymore But they can't get them for you

As someone has already stated. Be sure you only have one gasket in place.

Whether it's the old one, or the new one, just be sure you don't double up on it.

NAPA Gold #1143 works for me. Made by WIX. Very high quality.

In a word, yes.

That canister "O" ring looks mighty narrow and fragile. I hope it
doesn't break apart while trying to get it out. The jewelers screwdriver
sounds like a good idea. Thanks for all the imput !

Doesn't matter if it breaks - you throw it away anyway. I use a scratch awl, with the last 1/2" bent 90*.

Actually is it narrow and VERY TOUGH.

I use a dental pick.

Nowhere Man

You would. Do you ask the engine to rinse too

I use a dental pick to remove it. One tip when installing the new filter.

I spin the cannister/bolt until the can is close to the block. Then I push the can up tight agaisnt the O ring while I tighten the bolt. This will help prevent dislodging the O ring as the can wants to spin while you tighten it. It'll also help guarantee the can is seated in the groove and not cocked.

Years ago, I sometimes didn't change the O ring every time. A few times, I double stacked the O rings. I don't remember any disasters from this but I had enough oil leaks back then one more wouldn't make much difference.

Cool ! Thanks guys.
This is my 1st oil change since I bought the car last year.

Make sure to use some "good" oil with ZDDP additives if you still have the flat tappet cam.

Some of my knowledge base is because of mistakes. I made a lot of them back then.

For once we're in agreement. Exactly the way I do it. One in a row.
