Oil Filler Tube O-Ring

[Caman96]

96-98 5.7 Vortec
I’m looking for the O-Ring at the oil filler tube just above where it threads in. Anyone ever replace this? Might have to just remove and find one close enough. Can’t find anyone who has them. Not interested in buying this whole part.

If you can’t find one specifically, I’ll bet it’s the same as the one on the cap. Could probably buy a cheap cap and pull the o-ring from it.

Yeah I was wondering if they might be the same. Thx

Measure the old one carefully with calipers, and go from there. That's what I did for my oil cap. I then bought a couple close choices from the plumbing dept. and used the one that fit.

FWIW, this doesn’t say “which” seal it is. I messaged seller and reply was the information in description was all they had. Meaning…they don’t know wtf they have.

I would guess its correct, but you'd have a tough time convincing me to pay that much for an o-ring. Round O-rings are pretty standard like bearings. GM isn't designing thier own.

Apparently, an ordinary "320" size O-ring. I would want Viton material rather than cheap neoprene, but even neoprene should work for awhile at least.

Thanks for posting this, mine's been leaking slightly for years. I've simply "managed" it with a shot of Brakleen and a rag, but I would rather fix the problem than simply clean-up after it.

lol, no I wouldn’t either. It says it’s an Acdelco part. I was trying to get them to give me a part number, which they couldn’t. If it is correct size, it says it’s a 27.94 MM I.D. o-ring.
