Hi everyone, I'm a new member here. I have a 2005 Diesel with the 5.9 engine. I'm recently hearing about all these horror stories about this year with the number 6 injector having issues and completly killing your engine. Can someone fill me in? I've had this truck for about 3 years now. It has 83,000 miles on it and I baby it. Knock on wood, I haven't had any issues but do I need to sell? Is there anything I can do to prevent this from happening. I love this truck and I'm not really in a position to get rid of it and try to find something else. Any information and suggestions would be great!

 

Injector issues are completely random. The #6 piston is usually the one to melt, since it has the least airflow to it out of any. For instance, my 03 melted #6 and #4 I believe, and my 07 melted #3 and #6. A failed injector doesn't always equal a melted piston, but if you have less air available to a cylinder and just happen to have that injector fail, the chance of piston meltage is increased.

That said, most failures are on modded trucks. Yes, they can have issues stock, but I think you'll find most have some sort of programmer on them.

Personally, I wouldn't worry about it. If a failure occurs, hopefully you catch it before damage ensues; an injector swap is far cheaper than a full rebuild.

 

Welcome!

You shouldnt have anything to worry about as long as you take care of your truck and dont ignore the warning signs of a failing injector (white smoke, fuel in oil) and dont hot rod it with a programmer. These engines are very solid and reliable. If you really wanted a little insurance to prevent injector failure, always fill up at a busy gas station (sells lots of diesel), run a good fuel filter like the Baldwin pf7977, and possibly invest in an additional 2micron fuel filter system. If you take care of your truck and do regular maintenance on it, you can turn that 83,000 to 830,000 and never have a major problem.
