They decided to warranty the injectors at first because I found out they had a bad run of reman injectors about the same time my inframe was done. They confirmed that there was in fact a bad batch and decided to warranty them. When the mech came to our shop to replace them, he stuck a borescope down to have a look and every single injector seat was irregular. They are supposed to seal with carbon deposits after a certain period of time, mine were blown out like a cutting torch was burning the iron until it finally burnt the seat right out on one hole. They replaced head and all injectors. It was actually a post in a thread I started here on TTR that turned me on to the bad injector/poor seat machining issue. I joined here just for that reason, to see if anyone else had that issue. My engine was a C-15 6NZ in an '02 T-800.
