FEL-PRO 72401 O-Ring

Just like the OEM part. No leaks.

If you have intermittent lifter tap and oil pressure drop in your 2005 5.3, this is what you need. You’re here because you suspect that might be your problem. My oil pressure would drop to 20-30 psi then one of my lifters would start tapping. For a 2wd, this is a simple repair. I have a suburban z71 and you have to move the front diff out of the way. I managed by just unbolting the diff at the mounts and leaving the cv shafts in place. With an extra set of hands, easy peasy. I did it by myself in my driveway in about 8 or 9 hours, including a couple trips to autozone. Replace the oil pan gasket, put some gasket maker in the corners where the front and rear covers mate to the block. I would recommend also replacing your oil block off plate gasket as well. Mine was leaking and it was $5 at autozone. Also, you’ll have to drill out the factory rivets on the oil pan gasket. You got this.

Worked Perfectly for my 06 Silverado. Good quality O ring. Just a different color then the factory one but its same diameter and all.

Bought to replace oil pick up O-ring which was allowing air in. Did the job no more lifter ticking.

This bad boy right here is where itw at. I replaced this O ring on my chevy silverado oil pump tube because my truck had a tapping and low oil pressure. Now I have no more tapping sound and a much higher oil pressure. One of the best $3.00 I ever spent which saved me $1000 on repairs and perhaps a whole nother vehicle.

It's ridiculous that a $4 part is so important to the functioning of a $31K car, and that it's such a pain to replace. (It's also ridiculous that the price went up $1 between the search and the payment, which is why it's not 5 stars.) That said, it's in place and working fine.

The old one disintegrated when I touched it. This thing made my 5.3 Chevy run like new. Oil pressure was 22-25 psi now 40-50.. amazing

The media could not be loaded. As you can see on the video I had a very very loud tapping noise, almost a knock. I explored possibilities from a bad exhaust leak to rod knock. But something very distinguished was happening, the noise would come and go.So since I already had lower oil pressure, I’ve decided to pull the trigger and replace the Oring anyways.After the replacement, it runs amazing! 30psi after warmed up at idle, no tapping at all, extreme quiet engine with 340k miles. The old oring was crushed and rotted. It broke as soon as I pulled it from the pickup tube, and couldn’t withstand any bending without coming into pieces like a cracker.IMPORTANT INFORMATIONThis oring is black, not red. From what I could tell from the other reviews, it’s just a different color, and it does seems so. It’s the exact same size and thickness as it should be. Don’t worry about the color.Also, the truck in question is a 2004 Chevy Silverado with a 5.3 Vortec and 4x4. Dropping the front axle a bit was just another step, but not difficult at all. You got this!
