For a 2007 sierra 5.3 L, In the videos and VLOM mod instructions it shows tapping the VLOM plug into the oil pressure sensor port til it bottoms out. Is it a problem if the plug did not require tapping with hammer but instead could pushed into place by pushing on a socket with fingers. It seems to be a snug fit, but not tight enough to require tapping with hammer. I am having the computer delete done and have cut the gaskets in the VLOM.

Do collapsed lifters always make noise? I have a dead miss on Cyl 4 in an L83 and a ton of smoke from unburnt fuel. No unusual ticking noises though. Do fuel injectors fail stuck open often? Pulled plug and was wet with fuel. Next step is pulling valve cover and running on 4 cyls. Thanks, Jon

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!
