I’ve had two lifters drop on me and I got them unstuck both times by putting a quart of marvel mystery oil in her and redlining it
My buddy took a lifter tapping 4.8 and literally put a 5 gallon can of gas in it and put a brick on the gas pedal and walked away from it when she ran out of gas we put some more in her and she was purring like a kitten! He still pulled it out to swap in his built lq9 but my buddy threw that old 200k mile 4.8 in his Camaro and drove it another 4 years before he ever swapped it for a 6.2
I been running Marine Stabil in my jawn the green sh*t
The EPA is what drives this nonsense. Auto makers have to keep getting creative to increase power output because the engines have to run less efficiently to make "clean" air. It's a completely screwed up system. If engines were designed and tuned for "efficiency" you'd see many more diesel options as well as good gas motors like the original LS, 3800 V6, etc. It's all a game driven by mechanically unintelligent people, guised as 'clean,' that causes engines to use more fuel to do the same work. I saw it in all the engine development work I did over the years with diesel, DI 2 stroke engines, etc. I'm sure there is a balance somewhere in all of it, but it probably costs too much which eats into the bean counters conscience and shareholders pocketbooks.
so I paid $5,000 to have half the lifters/pushrod fixed.If it is still ticking put a BTR or Texas Speed Vvt/ dod delete kit in , that’s what I’m doing at time with a used motor after mine blew up 2011 6.2
I am in that boat now.......had it towed to a dealership due to an ongoing claim. It happened after the accident, while at the bodyshop, so it's an insurance thing now. I was at the dealership this morning for a loaner and #4 had a bent pushrod. Not sure HOW that even happens......never had a motor do that in my life.
