Z71JR

Understood, thanks for the info. Does 10k for the new motor and turning off AFM sound a little steep? I have received other quotes for more.

I was told by the shop they would delete the AFM for the new motor. IS that possible with junkyard motor? I was under the impression it would require some different parts.

Wanted to get some advice for the current situation I’m in. I have an ‘08 Sierra Z71 with 200k miles that started having a lifter problem recently and knocking badly. It also needs a rear main seal replacement and can barely keep any oil. The shop determined it would make more sense to do a motor replacement, considering labor costs to rebuild and not knowing the extend of damage. The quote to do the motor swap is about 10k for a brand new re-man with a 3 year warranty. I have looked into other options like a low mileage junk yard motor and that was about 2k plus labor. It is in good shape on the interior, but feels difficult to pull the trigger on the full swap knowing the trucks value and I will likely have transmission coming as well. Should I look into getting a rebuild and selling? Selling as is and buying another used truck with lower miles?
