07 denali oil pan gasket,pickup o-ring

[ny_summit]

Going to be replace the oil pan gasket as it's leaking, and the pick up tube o-ring. Should I go OEM gasket and o-ring? Is there a better aftermarket choice?
I've also read that vehicles without dod/afm can plug the pressure relief valve. Should I plug it? I want to make sure I get what needs to be done at the same time. Thank you!

I used a felpro gasket and o-ring on mine. No adverse issues. Never did more than clean out the pan and reassemble. If you are dealing with low oil pressure, do the valley gaskets as well

OEM lasted you 16/17 years.

Thank you. My cold pressure and cruising pressure seems ok. Hot idle does get sort of low. I plan on doing the valley gaskets but want to get the oil pan done first since it's leaking.

Gm or FelPro will both work well.. Whatever is easiest for you to buy...
Just don't buy either from a 3rd party seller as there are lots of fake parts
out there...
Good Luck !!

Do the motor mounts while the pan is off. Hellovuh lot easier.

You made this same post last May?
Here's what I did 5+ yrs ago and it's still going strong and dry 64k miles later:

Looks like I have, it wasent leaking too bad at the time and it's gotten worse. So need to get it done now and just want to be prepared. For the sheild on the pressure relief valve do I need it if my vehicle does not have afm? Or install it anyways? I've seen some post where people just plug it if you do not have afm so trying to decide what to do.

I had and still have success, by installing the $10 GM# 12639759 afm shield on my 2007 non-afm 6.2L L92 engine per the GM technical service bulletin:

Major Success - O-ring Replaced
I'm so pleased that I almost started a new thread.
I had the O-ring replaced and my oil pressure went way up (25 to 40) at cold idle and cold higher rpm (25-55+). The hot pressure is also up with 2000 rpm at about 50.

I'm including pictures of the O-ring. I observe the rectangular cross-section people talk about. It is supposed to be round. Also, I see one side is flatter than the other indicating the O-ring might have been pushed laterally when installed by the factory. Could be because of the hole locations on the pickup tube.
The Melling extra bracket did not fit because the pickup tube flange was partly over the bolt hole. So watch for that if you go that direction.
