I have another serious issue. I began having a knocking sound 1000 miles after new injectors from Exergy. I sent them in for testing and they said there is heavy metal debris in them. #3 and #6 are the only ones outside of factory spec and they said I caught the issue quick enough to cause serious damage. They are telling me that the metal inside injectors is my fault from sloppy install or from my cp3 or air dog not working properly. They gave me three options. 1. I can return injectors for a full refund and they will send My cores back. 2. They can clean the injectors and I will have to remove ALL fuel system components and reinstall injectors but they want over a grand to clean them. 3. They can clean them and put stock nozzles on at no charge and I can clean ALL fuel system components and run them stock to clear up some of the smoking issues I posted about before. I have no rail pressure or lift pump pressure issues besides my lift pump needing to be turned down as its running about 20 psi. They didn't tell me if the metal was magnetic so I don't know if it's the cp3 or something else. I did a search online about metal in injectors and in 2012 and 2013 There are 3 posts on another forum about Exergy BMS injectors having metal in them after 1k miles on two posts and one post a guy had metal in them after 15k miles. They wanted a thousand for there injectors to be cleaned as well. I need some advice on what to do. This kills me considering I'm completely broke after buying my gauges, air dog, and injectors. I can't afford another grand to clean them out. I am thinking about selling this common rail engine and switching over to a 12 valve if I keep the truck at all. I'm also leaning towards I just can't afford to own a diesel which kills me cause I'm in love with this truck and obsessed with Diesel engines and spent many nights in 15 degree weather working on it like it was 70 and sunny outside. I would gladly spend every night working all night no matter how cold it was but not if I have to be homeless and walk everywhere cause my truck is down.
