New (to me) 08 Yukon Xl

[BoxChevy216]

New to the GMT900, got a 08 Yukon SLT eith a gang of options, 230 on the clock, low oil pressure warning (of course, jist ordered new sensor) loving it so far, gotta do a little work to get it road worthy but it's very clean otherwise

These are nice looking and nice driving vehicles and at that age and high mileage with an oil pressure warning "on" they are almost FREE LOL. Be sure the screen gets replaced when you change out the oil pressure sending unit. Hopefully that is all that is causing the low oil pressure warning. Sometimes it is just that simple but other times it is not hopefully you got the price right and allowed for a engine rebuild if needed. Please post back if you get a chance to let the forum know if you got lucky on the oil pressure fix.

Looks to be in excellent shape and well maintained. Hopefully you got some service records.

If the press sensors doesn’t fix it, this likely will too.

Today I tackled my constantly low oil pressure by replacing the oil ring that fits on the oil pickup tube just as it connects to the oil pump.

The pictures below are the cold before and after the fix; hot before and after. My Yukon has 178K miles and I run 5W-30 with an AC Delco oil filter.

I would call this a success. I'll let you know if it quiets the cold (as in 30 or 20F) cold starts in the morning as my lifters have the LS usual tick for the first 10 or so seconds.

Photos are Cold and Hot before fix and then Cold and Hot after fix:

Nice, don't forget the oil pressure sensor screen, it sits below the sensor in the hole.

Thanks for the help guys! Got the new sensor in, so I actually get a reading, and it only took 20 min to swap. Now when I crank it, it's right at 40psi or so, and steadily drops, after about 2min it's back.to.0, if I let it sit for a few hrs, back to 40psi and drops. Sound weird to anyone? Guessing O-ring will be my next project
