I have a 2018 Titan with 120k miles. Developed the C7 knock a bit ago.

Some techs told me they honestly haven’t seen the issue actually lead to engine failure, but the short block is the proper repair.

I have an extended warranty, but I’d still be out of pocket about $6k-$7k on a 8 year old truck.

Truck is otherwise in decent shape.

Would you spend $6k-$7k on a short block at this mileage? Does a new short block meaningfully extend the life of the truck?

Appreciate opinions.
