LIFTERS 08 Tahoe 5.3

[George Owens]

Good morning, I am getting ready to order parts to replace valve seals and lifters. There is nothing wrong with the lifters as of now but I figure I would do it just to prevent anything from happening. seeing as though I’m at 180k. I want to keep the AFM I do not want to do any delete. repeat I do not want to do any delete. I use a plug in device that keeps me in v8 all the time and it’s been treating me well My QUESTION is does the VLOM get replaced as well? Questions and comments are much appreciated

The VLOM should be replaced, you will get the improved, more reliable design, should you wish to let AFM run again or sell the car. And of course, it's not 14 years old!

Don't forget to also replace the lifter trays with GM OE only.

If you don't have the new valve cover, consider getting that for reduced oil consumption. @iamdub knows the number by heart for a 2008! LOL

The improved AFM parts are much more reliable than your original parts.

Now with this new VLOM is pretty much plug and play or is this something else I might have to replace like the Cam? Or anything? And I would definitely need that part number for the valve cover

Also I think I did add GM lifter trays to the list are they all the same because apparently on rockauto they got a front and back I added 2 of each

And also again, do anyone got the part number for GM lifters both afm and non afm?

James @swathdiver got you squared away. +1 vote for replacing the VLOM, lifters and rocker cover with the updated parts! I recalled they had them GM lifter trays in an all-in-one pack, if that ends up being cheaper. Just found this on Amazon: https://www.amazon.com/PACK-GM-Lift...t=&hvlocphy=9025338&hvtargid=pla-570830290523

Do NOT get any that say something like "Replaces GM number xxxxxx..."

Rockauto just can’t seem to find the lifters

Ya

Rockauto just can’t seem to find the lifters

I would go Melling then, JB-2079 and JB-7011

May have to source other than Rock Auto, try Summit Racing and Jegs.

 

[George Owens]

Just put this order in, may have to look elsewhere for the lifters and vlom, valve cover etc

As much as I’d want to I saw a lot of bad reviews on parts that wasn’t GM, ac delco etc I’m really iffy on engine parts

I believe that Melling is the OEM manufacturer for GM lifters. I have one here on my desk beside a factory lifter from my 6.2 and they are indistinguishable inside and out.

What spark plug did you get that was only $3?

 

[George Owens]

Ac delco platinum

I'm with you there except when we know who the OE supplier is. In this case, Melling is or was an OE supplier for many parts on these engines, oil pumps, cylinder liners, camshafts, lifters, etc.

 

[George Owens]

I’ll guess I’ll consider them if I can’t find the ac delco, I just called a dealership and for 4 non and active afm they want $1k just for parts and to take the cake they not allowed to give me the part number on the phone crooks

I forgot to ask you these lifters, they they updated ones? Cause when I ran them they kept saying won’t fit my vehicle

 

[iamdub]

Ac delco platinum

Just looked 'em up on RA. I see whatcha got now.

I don't think ACDelco actually manufactures anything. It's the name branded onto those products made by others that meet GM's standards, and they're sold as that ACDelco brand. There are three levels of GM standards: Original (formerly "OE"), Gold (formerly "Professional") and Silver (formerly "Advantage"). Only Original/OE are the same as what it left the factory with. The other two are quality and price levels of aftermarket variants. Based on everything else they made for GM/ACDelco, I don't see why Melling wouldn't have supplied them with lifters. Johnson does or did as well. Or maybe it's that Johnson makes the standard lifters and Melling makes the AFM lifters. Either way, I'm pretty sure you're just paying for a name out of those two.

Of course, the latest and greatest! 12645725s are in my truck (since 2016) and that number has been superceded to the other.
