Gulf Coast Rods

Well here's the culprit, lifter collapsed, making the push rod come out of the lifter, then jamming against the inside of the head.
For those that know about the AFM (Active Fuel Management), it has been tuned out of this Denali for a couple of years before this happened, in other words the only REAL way to do the delete is to suck it up and do the mechanical delete as well as the tune. This will ensure you'll have a trustworthy engine. FYI everyone I've done the deletes on have gained MPG usually 2-3 MPG average, running on all 8 cylinders all the time vs the V8 to V4 switching, from the factory to save fuel. Thanks EPA for causing this nightmare for people🙄
To top it off, to whomever worked on this engine before cough...cough..(dealership)... why couldn't you just use the correct length bolt on this intake, instead of using a nut to make up the difference...and yet it still didn't work, the nut turns freely. (See finger points)

Just posting some car pics, some under construction, some need to be detailed, some need a roof.😉
