Here she is, just not running right - Evotrucker - 08-03-2018
A little back story, I got this vnl670 with a cm870 in it. Only reason I got it because it had a fresh overhaul done to it.
3 weeks after working the injector takes out the 5 cyc liner
RE: Here she is, just not running right - Evotrucker - 08-03-2018
I got 6 brand new injectors and replaced the piston & liner in cylinder 5. Replaced all of the rings in all of the pistons. New Oilers and some small other small things and had the turbo rebuilt also.

Congrats on getting it back together. Im just hoping that you took that video before it was warmed up or is just after the 1st fire off. It has a slow building surge you can see and hear and a fuel knock thats shaking the engine. Watch the fuel water separator dance then stop. If it was warm then you may want to have a good look at the fuel actuators. Run a cylinder cutout test. Sounds like you have an injector not firing or a bank of them not responding right.

Thanks! Will try to get to that today. I'll post another vid when I get done.

Deffinitely need to track down the source of that knock b4 u lose another cylinder. Keep in mind theres plenty injectors that r bad from factory.

I have seen bad programming make them run like crap too. Just mentioning this for those who may not know.

If your unsure of the programming, back it up then put a original factory file in that belongs to that engine and see if there is an improvement.

what section of programming would do that? Timing?
RE: Here she is, just not running right - Evotrucker - 08-03-2018
Hey rawze, I got in touch with uni about the programming. He said he would take a look at it for me :).
So we did a cut out test and found out the right fuel actuator was bad. When I fired her up, it took a minute for the air to get out. She started to sound a lot better and ran a lot smoother.

so the mechanic is telling me its not the injectors but im skeptical so idk.
after i put 2 different fuel actuators on to test it, after a initial 10 seconds or so the engine was doing find. no shaking or nothing, was better then i thought. so i went n turned her of n got some lunch came back maybe a 1 hr later to turn her back on and went back to acting the same.
then i took 2 actuators of to see if there is any fuel coming out of the ifsm holes and there was good flow and repeated the same on both sides. good flow on the other side as well....
not sure what else to do, so monday morning im going to sen uni the file he was asking for him to check it out.
