My 2013 Silverado 5.3L has almost 260K miles (very dirty). I unstuck my # 6 intake lifter and installed the VLOM plug and removed the gaskets for the towers. Now, after a few hundred miles, I have a misfire on that cylinder again but no ticking. I would like to replace the lifters but don't want to buy the full delete kit or deal with the cam. If the factory cam is good, can I just replace the lifters, keeping the AFM style lifters, etc. but have the VLOM plug in place and ECM tuned? Thank you in advance! Here's my plan:
Replace lifters with OE lifters
Replace lifter guides
Replace rods (original ones were nasty - caked-on carbon, etc.)
Do you recommend replacing the valve stem seals? Or, is there anything else I should look at or do while I have the heads off?
Thank you so much for all your videos and knowledge! I have learned so much!
I am going to hijack this thread for a minute as I am in a similar situation.
2010 Silverado had a collapsed lifter and we replaced all the lifters and new VLOM then we re assembled the truck and cylinder 1 had both AFM lifters colapse :( then I came across the cpr tool and was able to save the lifters without taking the truck back down sure wish I would have found this out first on the delete
Currently the ecm is in transit to LT1swap for AFM delete
and a CPR VLOM plug is on its way to me
After installing the plug do I plug back in the VLOM as the program is deleted or leave it unplugged?
