Are the 03 LB7 injectors covered under warranty for 200K miles and will warranty transfer to a new owner? Any problems to watch out for with 105K miles? Considering purchasing this truck.

This has been discussed many times. Do a search and you will find a lot of information. And yes they are covered.

Glad to hear the warranty will be extended. I have a 2003 with 36,000 miles. Is anyone experimenting with some of the bio-diesel making equipment and are there any downsides to using it?... injector failure ..?
