oil fill tube question

[Tbruz]

1997 5.7 Tahoe.
I have a leak under/in the oil fill tube where it inserts into the valve cover.

GM part is 12551357 for around $40.

Can't seem to figure out how to remove it to check for a crack down low or a bad gasket.
Does this even have a gasket/o-ring between tube and valve cover?
Any inputs appreciated.
Thanks

yes on the o-ring. it has probably has just shrunk over time. it happens. iirc get a good grip on it and yank that sob straight.

btw o-ring should be included in tube kit.

try unscrewing first just to be sure.

Sunlit thanks,
Twisting/unscrewing did not work nor did pulling on it.
Any chance its nutted from inside the valve cover?

possible but i don't see a nut in the parts diagram below nor is there a part number for one. regardless you know the ring comes in the tube and is not available separately so you know you have to order it. so i suggest doing so and inspect it when you get it and even post some pics of new, old and job here. sorry i could not do more.

From what I remember from when I did my rockers, it unscrews.......need Kung fu grip.

Maybe a little strap wrench too?

I got it to turn about a quarter turn but no joy in removing it.
Going to order one this week and will figure out how to remove the old one once I have the replacement in hand.

Tbruz have the same question. What did you find out? Does it unscrew maybe with lots of force??

It unscrews but it's probably gunked up and I dont remember if the obs ones go a quarter turn or full screw lol
