ACDelco 12612350 Original Equipment Gasket Review

Painful installation. You need to remove the front differential. Front drive axle. Rear Crossbar. Separate the CV axes. Only lower the rack to remove the oil pan. I had to drill out the rivets on the factory seal. It took me and a friend 8 hours. It would be a lot easier on a four wheel drive truck. I have a Silverado 1500LT 2011 5.3L V8 Z71 4x4

Installed this gasket on my 2002 Suburban's oil pan. The gasket is made of durable metal and rubber for OEM compatibility and function. It is installed according to the instruction manual, which indicates the tightening torque and the absence of traces of oil leakage along the underside of the car. I recommend this gasket if your sump is leaking/spilling oil but with my car doing 148,000 miles I hope I never have to replace it again.

The factory gasket is riveted to the pan and the ACDelco gasket is exactly the same. It has 2 small holes for your new rivets. Once the old one has been drilled and cleaned, simply rivet the new one. This saves you from having to dislodge the gasket when reinstalling the pan. It was easy and no leaks, thanks. You have the option, you don't have to use new rivets, but this makes it a lot easier and keeps it in place while you screw it back on.

Obvious signs of failure of intake manifold sealing ring began ie flickering pressure needle, never dropped below 40 but definitely needed immediate attention. The OD of the old oil inlet o-ring is flattened out after 149000 (not bad) used this oil pan gasket (12612350) with the FelPro part (72401), be sure to use the RTV in the four corners of the block and the Tighten bolts to specification. No issues with fit, functionality or leaks.

I originally bought and fitted another established brand because people were picking on it because of the assembled metal frame. The other solid frame was still leaking next to the oil filter (yes I used an RTV on the corner block gaps) so I bought this GM. I removed another gasket and compared them. The GM has a slightly different compaction trajectory that covers the block better and pivots corners where it's critical. Installed this GM gasket, no more leaks!

Not cut from one piece of material. 4 separate die-cut pieces joined at the corners like the outer edges of a jigsaw puzzle. I was specifically looking for this AC Delco part because I wanted to use OEM on my Silverado. The original Delco AC gasket that I removed was solid and much better. I think a lot has changed in 18 years. Cut costs, maximize profits, right AC D? LS is shorter, I need to change it. Maybe the pads are to blame, maybe mine. I'll definitely use a different manufacturer.

Feels and fits better than OEM. The original gasket is riveted to the oil pan and requires careful drilling. This replacement does not need to be re-riveted, just tighten from the innermost screws to the outer edge. Don't forget to buy an oil filter housing gasket as well. It would also be nice to change the oil pickup tube sealing ring. My oil pressure dropped to 12psi after changing the oil pan gasket, but went back up to 40psi after replacing the weak o-ring on the downpipe.

So far fixed the oil leak on my Silverado 08 with 155k. Installed the recommended deflector and a new o-ring. Oil pressure is normal. The engine sounds and runs quietly. The only problem was that the old gasket was riveted and trying to hold the new one in place when reinstalling the pan. I've cleaned the oil pan of mud over the years. I hope I get another 155,000 miles. UPDATE 8/21/2020 Should have done an update a few months ago. Replaced all recommended items, this seal failed after about 1…
