    Part installed due to oil consumption service bulletin.
    A pain to install. Have to remove front differential. Front drive axle. Rear crossmember. Disconnect CV axles. Drop steering rack just to take off oil pan. Took me and a buddy 8 hours to do. Would be significantly easier on a 2WD truck. I have a 2011 Silverado 1500 LT 5.3L V8 Z71 4x4

    5.0 out of 5 stars Easy install once oil pan is dropped. Should help with oil issues on Tahoe.

    My buddy installed this for me at his shop during a major overhaul of many gaskets and seals replaced on my 5.3L 07 Tahoe. Apparently it was very easy to install once the oil pan was dropped (which wasn’t so easy to get to) Should help with my oil issues, I believe there is a TSB for this specific issue with this resolve it. Research and check it out. Hope it works.

    5.0 out of 5 stars I don’t think my burban is burning any more oil!

    Wow what a chore to install this silly little part! Took 7 hours total to drop the diff, steering and other stuff, clean things, install new parts and put back together again. While you’re in there, definitely replace the oil pump pick up o ring too… ours was cracked and I’m glad I replaced it. Why gm didn’t install these right off the get go is baffling to me. I did this and replaced the drivers side valve cover and we have no more Smokey startups. Hooray!

    Of all the things I've purchased on amazon, without a doubt, this item was exactly what I expected. It's a shield for your pressure relief valve that goes inside your oil pan. Apparently, it works.. I've had zero issues since installation.

    I found this updated piece incredibly easy to install. Okay I removed the 5.3 engine and did the gm recommended service which includes replacing the cam, lifters, all the intake and exhaust valves, oil pump, timing chain and all the gaskets along with the oil solenoid

    This is an important part to install on your 07-14 Chevy 5.3 that is burning oil. I recommend getting the updated drivers side valve cover with relocated egr vent. this also helps with oil consumption.
