5.3 Top End Rebuild
#1
![Question](https://chevroletforum.com/forum/images/icons/icon5.gif)
Hello,
I am about to rebuild the top end of my '09 5.3 AFM "0" motor and have some basic questions. (300k on a 2WD Suburban)
I was elbow-deep in 350's for most of the 80's and 90's but haven't done much on new motors. I am rebuilding this one because the shop that replaced the oil-sending unit did not get oil pressure into the top end, and several lifters collapsed immediately when they started it up. They claimed it was a worn-out engine and wouldn't do anything about it.
Q1: Is it worth removing the hood, radiator, grill, etc to do a top-end rebuild? Should I pull it?
Q2: I plan to do a DOD/VLOM delete, any thoughts here?
Q3: Should I upgrade the camshaft as long as I am replacing it?
Any input is appreciated.
PS: Both of my Suburbans exhibit the Stabilitrak/Power Steering/Non-Shifting issues randomly. Have never heard a comprehensive reason.
