GMGenuine Parts 12639759 Engine Oil Pressure Relief Valve Deflector

If your changing the oil pan gasket while your in there add this part if missing and change the oil inlet tube o-ring. This part helps from oil spray in engine and burning oil.

Awesome item works as it and fits perfectly

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.

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 bought this part for my 05 silverado and realized that this part does not fit,but it did work for my 07 yukon nbs

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.
