6.0L valley cover gasket

Hey all!

I found a bad leak coming from the valley cover gasket. However, it’s a whole assembly, Damnit!

anyone else replace one of these or know if you can get just the gasket?

I'm pretty sure it's the same vlom gasket as any of the afm ls engines?

FEL-PRO MS 96871. a local parts store should have it?

on a side note. that looks nothing like the vlom on my 2011 yukon hybrid.

how odd

Thanks! I’m researching. It doesn’t look like I can take it out without breaking the little plastic connectors to the inner gaskets. Hmmm

what year is yours? mine is a 2011


looking at your Pic, the gasket looks to be in good shape. I don't see it ripped up? it's pretty common for the bolts to come loose. I didn't have a leak, but I reused it without issue. in your case, unless you wanna buy a whole new vlom cover. I'd probably just use back silicone rtv on the gasket and put it back together. Just straight black rtv, it's a bit hard to find but don't like their ultra black. black or Grey is the only ones I have any luck with. the others don't seem to be very oil resistant.


the sensors can leak pretty commonly too.

Holy crap!

VLOM (valley cover)

is it possible to retorque the VLOM (valley cover) bolts ? with out taking the engine apart? i can literally see the VLOM (valley cover) poking out from under(two front bolts are visable) intake manifold.. I heard about the 07,08,09 having loose bolts causing AFM catastrophic failure in...

Most of the bolts on my cover were lose! I was able to take them out by hand. WTF.



On a second note, this post also said the cover I have on my 08 Tahoe is not the revised cover, which you have, j91z28d1

​

I’m wondering if it’s worth a try to clean and torque down to spec with loctite. I can always take it apart again if it still leaks. I doubt I’ll be able to get an OEM assembly in town.

Thoughts?
