Oil filter adapter seal installation
 
1 Attachment(s)
I have a 1987 vet that started leaking oil above the oil filter. I’m fairly certain it is a bad seal above the oil filter adapter and I found a replacement on line but am perplexed on how to remove the adapter. See photo attached. I was told that the nut unscrews but I can’t find a socket to fit and I’m wondering if it isn’t a nut but a pressed part of the adapter and whether the entire adapter unscrews after unhooking the oil lines. All input welcome.Attachment 25486

Maybe this will help get you going - looks fairly straightforward:


Good luck -

Thx but I’ve seen this video before and it is an entirely different adapter with separate bolts!
I need to know how to remove mine since the nut(sides are bigger than any sockets that I can find) which makes me believe it is not a nut! If so how do I remove the adapter? Will a strap wrench work to turn the adapter once the oil lines are removed? Is there a special tool?

I’ve Googled things a bit and agree that the instructions are elusive without a shop manual diagram.

Finally was able to remove the adapter! Had to machine a 1 1/8 in socket flat to remove the slants on each face so I could grab the thin nut and crank it off! It comes apart and I attached photos so others can learn!Attachment 25699Attachment 25700Attachment 25701

Sounds like you brilliantly figured it out. Impressive. I’ve learned from it. Not to own an ‘87! Seriously. How often should a 5.7L oil filter adapter enable or directly cause a leak?

Once in 32 years!

No issues with my C3. Yet.
Now I have to go knock on wood.
But, I don’t even see them offered in the two C3 parts catalogs I get, so I’m hoping that is a good omen.
Good job getting to the bottom of it.

Now I need a new seal! Hunted for weeks with no luck! Seal is 3 3/8 in outside diameter! Anyone know where I can find one?

Took a regular oil filter and removed rubber gasket. Was a llittle too wide to fit oil cooler so I placed it on a plastic cup so it wouldn’t move around. Then used a Dremel high speed grinder to carefully narrow gasket to fit! Should work.Attachment 29303Attachment 29304Attachment 29305

Been there Done that!
Don’t repeat my mistakes
I machined a socket so it had no bevels
Removed the oil seal adapter and changed seal
At least 4 times because seals are impossible to get right fit
Tried gasket sealers
Still oil leak
Replaced oil temperature sensor which sits above oil filter assembly using several different sealants Still oil leak
Replaced gasket on rocker cover
Still leaked
Finally removed distributer cap and replaced oil pressure sensor which was leaking right out of space between ceramic and metal housing not where threads were
No more oil leak!!!!
The oil pressure sensor is likely your problem!!!
Start there
It sits on the passenger side slightly and the schematic drawings make it appear to be over there but when it leaks the oil runs down the driver side of the engine on top of the oil cooler adapter!

Good luck
