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

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.

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