Allys Auto

I have a 2008 Tahoe hybrid that I bought from Copart auction about 2 years ago it didn’t run when I bought it after getting it back to my shop and checking it out I found it had a broken lifter I am a mechanic and I decided to rebuild the complete engine since I bought it non running and didn’t know the history of it and was doing the work myself. when I removed the old cam bearings to install new ones the #1 bearing was worn pretty bad and allowing oil to leak into the cylinder wile the rest were not warn at all and from what I could tell it was being driven that way for a long time till the lifter collapsed. The Lfa is the same as any other gen iv ls.
