Well worth the money, came with 3 pressure springs to choose from, worked great on my tired ls3
Reviewed in the United States on October 6, 2023 by Daniel Huffman
This part was worth every penny and does exactly what it claims to do. I would install it on every suburban, Tahoe, and Silverado I work on in the future if they have lower than normal oil pressure. Fits like OEM and I’m not worried about the engine getting damaged or the check engine light on for low oil pressure. Excellent upgrade.

Well, this is going to help, but it's not your problem. 6.0 iron block guys, check your pickup tube o-ring first and change your oil to 15w40. If you're getting sub-20psi hot idle oil pressure, your cam bearings are shot. This pump won't fix low oil pressure at idle. That's not it's purpose. It will however give you 50+ psi just off idle and is consistent, if you use the COPO Camaro spring that's included in a separate bag. LQ4 owners, you WILL need to slightly lower the oil pan in every application to do this job by itself. Your pickup tube doesn't have the cheesy welded flange that you can easily turn around on all other LS engines. You need to drop the pan about 1" to gain access to the pickup tube bolt. I didn't remove the oil pan bolts, just loosened to their max and dropped the pan slightly. With 5w30 oil using the COPO spring on a 265k mile LQ4 with worn cam bearings, the engine will attain 20 psi at hot idle and 50+ psi above that. Same engine using 15w40 will net 35-37 psi hot idle and 50+ psi above idle. The pressure regulator is set to somewhere between 50 and 55 psi. All thsi being said, my LQ4's bottom end is healthy. The only problem I know of is cam bearings worn out of spec causing low oil pressure. This oil pump will help if you use the right combination of oil and pump regulator spring.

Installed on 2007 Tahoe 5.3 Flex. Had the hard o-ring issue on the oil pump pickup which caused low oil pressure for the first 10 minutes after cold start. In my slanted driveway idle pressure would drop to just above 0. Once the oil was nice and hot the o-ring swelled up enough and oil pressure returns to normal. Very weird issue. 156k miles by the way. Since I had to drop pan anyway to replace the o-ring I did the oil pump as well. Left in the high pressure spring. Works great! Hot idle pressure with 5w-30 at about 38lbs is very reassuring all is well. I thought I had a little lifter noise at idle. If I did I don't now, very quiet. 55lbs or so on the highway. A little hint. Get the flywheel locking tool. The balancer bolt has to be very tight according to GM specs. Torque 240ftlbs with old bolt. Remove old bolt. Screw in new bolt and torque to 37ftlbs and turn an additional 140 degrees. Overall very happy with this pump!

Package had everything Included for the install of the oil pump. I did have to purchase an additional gasket kit for the front cover and water pump. I did install a new water pump at the same time since I have a 130000 miles on this motor. I was on a road trip when the factory oil pump failed, the relief valve stuck open. It did free up when I ran some Marvel Mystery Oil in the motor , but I went ahead and replaced the pump anyway. I attached pictures of what the factory pump was giving me for psi and has from day one. I used to see 28 psi to 25 psi range at full temp in the winter months. It is the HD package the PSI was always on the low side due to the oil cooler. After install of the oil pump at full temp I'm seeing close to 40psi Temperatures are also running a little cooler because of the new water pump and a complete coolant flush, along with that I went with a 180 degree t-stat . All in all very happy with this oil pump, I did just install it. I don't have any mileage on it yet but I'm sure it'll hold up Melling is known for quality products. I'm confident it'll hold up to the test of time. Overall the install took me 2 days but I did run into some snags. Around 8 hours per day, I did skip dropping the oil pan and front differential to get to the bolt that holds the collector in. I was able to work that bolt out at first I used a bent 10 millimeter wrench to get it loose. Then I tied some fish string to it and backed it out the rest of the way with a hook tool. Took a lot of patience but it worked. When I reinstalled it I put that bolt in the hole that's more accessible, I added a washer so it would push the tube into the oil pump, and used a lot of red Loctite.

QUALITY PIECE FOR ANY LS BUILDER. CAME AS DESIGNED WITH CLEAR INSTRUCTIONS OF WHAT TO DO. ONLY GAVE 4 STARS BECAUSE THE ORIGINAL BOX IT CAME IN WAS BEAT UP AND IF I WAS NOT CAREFUL THE PUMP COULD HAVE FALLEN THROUGH AND HIT THE GROUND. OTHERWISE GOOD PRODUCT.

The media could not be loaded. I personally use these in all my ls builds it’s cheaper than most auto parts m365 and this 10296 has more /high pressure and high volume great bang for buck @reclusiveperformance

Melling definitely needs to update their product shipping box. Both ends of the box were open and the pump was flopping around in the Amazon box so guess im gambling on keeping and installing it. Not real immediate signs of physical damage though
