So how much should a shop charge me to replace my oil pan on a 2011 4x4 Tahoe?

They will probably go off of book rate which includes dropping the front differential and cross member as well as lowering the steering rack.
Not sure what that book time is, but if it’s 4 hours at $175-$200/hr ship rate, plus the pan, gasket, oil, taxes and shop supplies, you’ll be in the $1200 range I’m guessing. Others may have better intel on shop time for this.
I would have them replace the o-ring on the oil pickup tube while they have the pan off.

Shop time is 3.5 hours for a 4x4.

I forgot to mention that I will provide the new OEM oil pan and oil pickup tube
Glad I wasn’t too far off on my time estimate with my 4 hours.

I’ve had it done 3x on 2 different trucks. Deff do the oil pump o ring.
If I had to do it again I’d do a new oem oil pump or HD oil pump.
I put up with the oil leak until I had to have the trans pulled for service or replacement though. It cuts the labor to an hour and allows 100% access to all the bolts.

It's about a 2-hour job after you've done several of them. But that's where they make their money... Getting paid off the book time. I'd say dive into yourself. If you could change a water pump, or do your own brakes... The oil pan is no big deal. Do the o-ring, install the aftermarket girdle around the pickup tube flange to utilize both threaded holes on the oil pump.... Instead of the OEM having just one bolt. Small amount of RTV in each corner of the oil pan gasket. This is one area where the felpro oil pan gasket is a lot better than the OEM. Clean your pan out and the oil pick up tube screen.... Show your wife how much money you saved.... And she'll be all in on picking up some more tools for you

I have the AFM/DOD deleted via tuner.
There's a whole range of opinions on that pressure relief valve in the oil pan. Many people just plug it off. Considering you have a pressure relief built into the oil pump, it does provide a redundant method of pressure relief. I personally suspect it has more to do with high RPM pressures.... I would suspect the component most at risk from extremely high oil pressure, such as running at 4,500 RPM+with cold oil would be the o-rings under the VLOM plate. Perhaps the oil filter itself as well. If you do a full delete including the VVT, normally you install a standard pressure oil pump and just plug the thing off. (The VVT actually requires the higher volume oil pump more than the AFM DOD system.) In either case, in the quest to locate oil pressure loss and going for the pickup tube o-ring, this valve is often overlooked.

My engine didn't come with AFM/DOD but I installed GM relief valve deflector# 12639759 per this TSB: https://f01.justanswer.com/ebrock63...il+Consumption,+MIL+ON,+Engine+Runs+Rough.pdf
zero oil pressure and consumption issue(s) since then (2018)

Couple months back I was reading that the valve is specifically for the protection of the AFM lifter solenoids. Apparently at around 65 PSI oil pressure they will fail. So if you don't have AFM or have it turned off, the valve can be removed and plugged off. Technically though, it probably doesn't matter as it releases pressure far above with the oil pump releases at .... But, it is one more thing to fail I suppose. I've read numerous times of people with a non-afm engine finding the valve in the oil pan.... Most people chalk it up to GM using the same pan on multiple versions of the LS engine.

Gawd I love TSB’s. They’re written in plain English and pictures. Pictures with arrows and circles!!
I always felt like the guy below when I walked up to a cocky service manager with a TSB in hand.

If AFM was disabled, does the valve still need to be replaced? Thanks.
The bolt and washer is like $16 on Amazon. Convenient I suppose. No doubt you could get it cheaper at a hardware store. 14x1.5 mm. Match the length of the threads to the relief valve removed.
