Oil Pump failure lottery ticket winner
So last Friday I start up the car and I got the dreaded 'low oil pressure" warning. Figuring that it was another pos oil pressure sensor I pulled the intake and replaced it on Sunday. Fired it back up, still no pressure.
Towed the car to the shop my business runs out of and put a oil filter pressure gauge and the oil pump is shot. The car has 19500 miles on it, I've changed the oil every 4500 miles, mobile 1 only and a quality oil filter. This is completely f@cked. Anyone know a place in the Denver area that can do this job? I've got a guy at our shop that says he'd do it but he's 2 weeks out and has not done one on an LS3. The good thing is it happened in the garage and I could shut it right down.

Sorry to hear that, glad it did not happen on the highway. The only shops I can personally recommend are in Colorado Springs or Laramie Wyoming. If you are on Facebook, look up Camaro club of the rockies and ask about trusted mechanics. Good luck.

Hopefully you’re not replacing it with another pos GM oil pump.

For this, I would take the handle of a shovel and chase whoever invented these rotary pumps around the car and beat him until I had the last bit wood in my hand
And the next one would be the one who approved it for these engines at GM Golden oil pumps from 1 gen. SBC! Heavily damaged, but kept my engine safe. This bastard has first-class care and will break anyway

Ya, I've done enough research to melt my mind on GM LS3 oil pumps. I know melling makes then I'm hoping the higher flow pump will be better.

I used the melling 10355HV and am very happy with the pressures. I currently have 167k miles and have 32psi @ hot idle, 50-60 psi @ cruising, and 86psi @ wot with the spring that came in it. I tried the high pressure spring at first and my pressure was @ 60-70 psi at cruise with + 90psi at wot. I thought it was a bit much seeing that kind of pressure so I reinstalled the spring it came with because I was afraid that something was going to explode. lol

10355 is a good HV pump and a direct replacement in the autos. The 10295 is the direct LS3 replacement and high pressure, but not high volume. There is also a 10296 that is HV/HP. Most guys run the 10295 on LS3s unless they have increased the bearing clearances for racing. I have never heard of any of the aftermarket pumps failing and I remember thinking how much it would suck if one of mine went out as I was reading all the threads on it and then it did. Then about 100 miles after the pump replacement, I spun a bearing and now it's 416. but I digress.
The issue is caused by the pressure release valve sticking open which is why you can see it on relatively young engines. I'm not sure what in the aftermarket pumps fixes that, but once you replace it there does not seem to be any further problems with the pump.

Pretty sure i put the LS6 pump on mine when it failed. More pressure than the stock pump and my stocker went 140k miles. I aint worried

I'm running the 10295 Melling in mine as well, with the spring that came in it. I see 39-42 psi at hot idle, and 50-54 cruising at 2k rpms, 65 at WOT..

I'm looking at the 10296 with the lower pressure spring. I'm shitting my pants worried that there is internal damage.
It goes to the shop tomorrow I'll get her back in 7 to 10 days. I've never been in love with a car like this, it's like dating a hot ass stripper.....a ton of fun until the bat shit crazy side shows up, with her pimp and the cops.
