Hazing and slight misfire - Which Injectors should I go with? BBI or Exergy?
So my truck started Hazing on a vacation trip up in Montana back in July. Had me really worried because I still had to tow the 10K Camper back to Utah. It hazed the most when it was cold then would be fine after you got it warmed up, but felt down on power. Rail pressure was normal, Idle was fine, Truck acted like there was nothing wrong but hazed.
Hooked the trailer back up to go home, still hazing, pulled fine though. Once we got back to Utah and I switched the tune back to '4' (IIRC is a 100+HP Tune) it stopped hazing at all! So I chalked it up to be a tuning issue that I procrastinated to take to my tuner (Starlite Diesel) while I caught back up at work. Then, it started hazing again and this time it's missing. Sounded like the AC kicking on or something (I already wrote a thread on this.... This post has been a long time coming.) but the AC and all of the HVAC controls are off. (Checked the Compressor clutch to make sure.) Rail Pressure is still normal except when I hear the Miss and it drops. It will go from 5.1KPSI to 4.2KPSI then Spike to 5.9KPSI then go back to it's normal 5.0 - 5.4KPSI. But it still drives normally and only misses at Idle.
So as a test, I took it on the freeway and laid into it to see if it did anything differently... I noticed a lot more black smoke pre-boost and didn't clean up until about 2800RPM and 24-28 PSI Boost and still had more black smoke longer. I played around with the tunes a bit and noticed more smoke on all tunes. 1-5 on the CSP5 switch. I also notice; at WOT, Rail pressure won't go above 22KPSI. My first thought was a weak FPRV, but that wouldn't solve my hazing issue. Thus - I have a leaky injector... No blow-by at all.
One other thing that I've noticed... It stops hazing almost completely if I run some Power Service Fuell additive, but once that tank is gone, it starts back up again. Since I don't want a band-aid to be a permanent fix, I've parked the truck to avoid any chance of washing out a cylinder. Also - the radiator cracked last week end while towing my project truck to a buddy's place for safe keeping.... Nothing bad. Just enough to not notice it while towing but notice a drip as soon as I got home.
Now that I've laid out my long-winded story... BBI Vs. Exergy?
I've heard nothing but good about both companies but I'm on a tight, TIGHT budget and will have to save up for injectors either way. I WANT to go with bigger injectors, but my wallet won't allow for bigger injectors and the funds for a turbo that will make it worth it. So I'm going to have to go with stock flow rate. I want to get injectors that will take the abuse that my current ones have, as they are the original factory injectors that came with the truck in late 2007. They have 250K on them now. The truck has been deleted since 130K miles and driven HARD the whole time. I know both previous owners who verified this.
First owner is a foreman for a cement company that used it to haul cement, tools, crew, water, asphalt, equipment, ETC... and floored it every where. (his words, not mine.) Second owner is a barrel racer/horse rancher who bought it, deleted it immediately, and used it to haul his horse trailer and tractors around for events and what-not. He stated that he blew 2 head gaskets and 3 turbos and said that he was "not nice to that truck." He got rid of it because he was worried about the injectors being next. Then I bought it with 180K miles on it at auction and used it to haul hay and did some hot-shotting with it for 2 or 3 years before I finished school. Then I blew a head gasket in a pi$$ing match with a BMW on the freeway... (PSA - stock head bolts don't like 4300 RPM) I have a thread on that also.
The point to this story is this:
I need to get injectors that will take everything that I regularly throw at this truck. I don't pull heavy anymore but still daily it and, Admittedly, drive it like I can afford to fix it. I can't, but I still do. Pay to play, right?
Thanks in advance, all!
