Main and rod bearings on 2011 3.8

High Mt. Jk 63 · Feb 25, 2025

Hi guys just a question....Has anybody put main and rod bearings in their 3.8 engine ???? What I would like to know is the bearings all standard with no odd sizes to make them work...I've got 175,000 on my engine and was going to check them and probably replace them...

Is your oil pressure getting low, the bearings should last longer then that?

No, oil pressure fine...Just trying to prevent a spun bearing...

Sir? Sir! Set the bearing down gently and step away...

Oil samples will let you know when a bearing is failing.

I had a granny failure so while it was out I had rear main, seal and oil pan seal replaced. I figured they'd go some day so at 110000mi it was done.
No problems, I went with a Jasper rebuild and so far(25,000mi) so good.

Oil samples:

I know there are others that do the same, I use CAT SOS. I pre pay for a dozen and use as I need for our equipment. Single SOS is about $25 iirc.
