Replace engine, rebuild, or sell truck? 2007 Freightliner Classic

We need more 411, you didn't mention what motor it is

 

Rebuild it. You know what you have.

 

Yàaaaa that's a D60 baby

 

If your going to keep the truck drop a compleat detroit reman in it. Then you have 3 year Warrenty and be good for another million.

 

You'd be looking at around $15k for a reman engine plus a $5k core charge until you can give them back your old engine that came out

 

Inframe the motor. It can be done cheap if you shop around more. Once you get the motor redone, redo the interior yourself. Strip it all the way down. Insulate floors and walls. Dynamat the firewall. New seals and weather stripping on doors. New cloth driver's seat. You'll be looking cool on that stool and have intimate knowledge of what's going on in that truck. It will be riding quiet and purrr down the road. Much better than some new emissions nightmare you know nothing about.
