Well if ya can't figure out the part about removing the oil pan ya shouldn't be doing the job... It is a simple job ..

If you're not adding anything worthwhile to a conversation, maybe you should refrain from participating.

I'm sure there might be some tips that could be given, as there is in most any project.

You've been a might snippy lately

iirc the oil pan and the front of the engine comes off.
Be 100% sure the oil pump is the problem because this is a serious pain.

Don’t think it’s really worth it swapping the oil pump in place. imo yank the engine and tear down. If you dumped pressure- replace the bearings while you have it all ripped apart.

The lly duramax is a gear driven oil pump that is at the front of the engine under the timing gears. There is a known issue of an oring that goes between it and the block that will occasionally fail. There is supposed to be a “work around” where you don’t fully remove the pump to sneak in and remove the old one and slip in a new one. But this is done by flat rate mechanics who already know the customer is not willing to do any repairs beyond the seal. So usually someone that is trying to prep the truck for sale to sneak it’s issue beyond the knowledge of the future buyer. By the time the oil pressure is running low enough, the bearings are being worn heavily. This is akin to the old trick of a manual transmission making noise in the loose bearings so you chop up banana peel and put in there so the fibers get smashed against the bearing race hiding the noise.
Does it work- yes to hide the noise but a couple thousand miles later and you are tearing it all the way down.
Same thing here. When the oring fails you will have very low oil pressure because the pump is just bypassing the oil gallery inlet and squirting oil back into the pan.

The problem with learning how to do it usually ends up in damaging the drive gear. Unless a person has had a pump off and sees how to slip the new oring in- it usually fails completely. Not a recommended method even on your own truck on a budget. All you save is some labor time, because you already have to have the front and bottom opened up. No parts are saved.
