Is your 5.3 buring oil ... possible fix.
 

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

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 ...

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

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

I should have said Valve Cover ...

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

Thanks :metal:

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.

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

Re: Is your 5.3 buring oil ... possible fix.
 

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

Re: Is your 5.3 buring oil ... possible fix.
 

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.

Re: Is your 5.3 buring oil ... possible fix.
 

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.

Re: Is your 5.3 buring oil ... possible fix.
 

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

Re: Is your 5.3 buring oil ... possible fix.
 

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

Thanks

Re: Is your 5.3 buring oil ... possible fix.
 

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

Re: Is your 5.3 buring oil ... possible fix.
 

I can't wait for some results.

Re: Is your 5.3 buring oil ... possible fix.
 

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.

Re: Is your 5.3 buring oil ... possible fix.
 

Its now a waiting game ... :mm:

Re: Is your 5.3 buring oil ... possible fix.
 

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

Re: Is your 5.3 buring oil ... possible fix.
 

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
