I've got a good friend looking at a 2002 LB7, it has around 270,000 miles. Henry gave me the information for a VIN check and it showed the injectors had been replaced 3 times under warranty. The information my friend got from the seller has 2 other sets being replaced elsewhere. So the injectors have been done 5 times.He's flying out to Missouri to look at it but I couldn't think of why it would go through injectors so badly. Just looking for thoughts/opinions on why it would eat injectors. I've heard of 3 sets on 300,000+ mile trucks but not 5.
