Is your 5.3 buring oil ... possible fix. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

GM has a Valve Cover that has been re-designed that might solve this. Looks promising.

jjzepplin · 08-07-2020, 04:37 AM

Where is this cover? I was looking at the LS6 valley pan that has a built in pvc type thing that eliminates your in line pcv. Looking inside my intake looks like I have missed quite a few oil changes inside my fuel tank.?

Driver side manifold cover ...

Oh. I thought you were serious. My bad.

the baffle inside is the new piece that was re-designed. I'm going to try this on my 2009 Yukon that fills the intake with oil and smokes

jjzepplin · 08-07-2020, 10:46 AM

Oh. You were serious. I am interested. Let us know the results.

Updated valve covers are mentioned in GM Technical Service Bulletin 10-06-01-008M
The link is a PDF of said TSB

Thanks

jjzepplin · 08-09-2020, 09:57 AM

Oh thank you! I suppose this fix should work on most LS engines. I now have 3. I just bought a 2014 GMC 5.3. I also have a 99 5.7l and a 2006 6.0 LQ9. I can use this info on all 3 most likely.

**70cst** · 08-13-2020, 08:18 AM

I'm installing the new Valve cover next Monday so hopefully my excessive oil use will decrease.

You sure about this bulletin? Sheet says years affected start at 2007?

I am fairly confident ... I spoke to my GMC dealership and they said the vlve cover was redesigned ... which syncs with the oil consumption issue.

**hatzie** · 08-13-2020, 05:35 PM

The valve cover was re-designed for AFM (displacement on demand) engines but that doesn't mean the non AFM engines will not benefit from the re-design.

I will find out after next week if this cuts my oil consumption ...

**Palf70Step** · 08-14-2020, 03:35 PM

This is an interesting conversation about oil consumption and synthetic oil use.

My 04 Sierra now has the GM redesigned Valve Cover ... so lest see if it works.

jjzepplin · 08-20-2020, 10:56 AM

I can't wait for some results.

**hatzie** · 08-20-2020, 01:35 PM

If it was motor oil getting sucked through the PCV breather system and not from excessive cylinder wear it should make it better.
I'm interested to see what happens.

I know it had something to do with the PCV Valve and the new design has a different designed baffles.

**truckdude239** · 08-25-2020, 08:19 PM

I had new cover installed in January along with all my leaks fixed I went from 2qts of oil every 1k miles to about 1 qt every 1500 I use to have smoke if I left it idleing for awhile and cut it off and restarted now I have no smoke at all so I believe it works this is on my 2002 suburban they do sell a pcv vavle with just a small hole in it that was suppose to help oil usage it didn't work for me but the vavle cover did
