Lame (but quick) question about 2012 3.6L oil change
I can't believe I'm asking an oil change question... forgive me, I've changed oil for over 20 years... and had to break down on this question...
Working with a 2012 GC 3.6L Overland.
Drained like normal, went to change filter and see that the "design" is no longer traditional... no big deal. Pull filter and went to install new unit and just happen to notice an o-ring fall from the box. I didnt recall seeing an o-ring on the old unit... I double checked everything to see if it was stuck somewhere, etc. Nothing on the old setup.
It made sense to use an o-ring though, so I put it on, but when I went to tighten, it was starting to "squeeze" out from alignment. Basically, it just didnt seem right.
I noticed the cap for the filter listed a torque spec of 25lbs. With the o-ring on, I only got to 10+lbs before it started to deform. At just under 20lbs, the o-ring was bulging out.
I decided to leave the o-ring off (pending research) and was able to get a clean torque at 25lbs without the o-ring. Everything seemed fine.
After looking online... everything says the o-ring is needed. But I never had one to start with. I get that it may have been a previous install error though. I bought the car used from a dealer with low miles and had a full history of maintainence at THE SAME dealer... oil changes and all.
I see the filters changed around 2014 models... whats the deal with this o-ring on the 2012 models?
