Is it a vp44 issue or an injector issue?

Posted

Hi everyone I'm trying to sort out an fueling issue that is making me too scared to drive :(. 

 

I put a nice fresh engine in my "00 and I'm getting a pile of white smoke at idle and 1/4 throttle. It also sounds as if I have air in the injector lines at idle. 

 

The vp44 is one off my old engine with a p0216 code so I'm wondering if it's an injector that is damaged or if the vp is having problems fueling 150hp sticks?

 

I'm new to the Moparman site but I'm very impressed by this community thanks for the info and your time!

    Yes HUGE issues with the shady pos. Do not trust ANYTHING that comes out of that mans mouth. I am less than impressed with anything Thoroughbred diesel as well.

    Or you can get quad with v2 tuning and solve a lot of problems with what you got, as lon as you're keeping vp.

    @jibayes yes I did and you can see where @Bluelinecody asked how to diagnose a pump without codes. it will also tell you what to look for to diagnose an ECM issue. As far as ordering parts I use Midwe

So idling truck for more then few minutes is not good at what rpm is oil pressure sufficient to keep things lubed up. 

 

Up north Cummins engines are idled for many hours in the subzero temperatures. Basically the oil pressure low limits are 10 PSI at idle and 30 PSI at 2,000 RPM's.

Well I never found the piece of the pushrod. I put a new pushrod and rocker on, changed the oil and put about 70 miles on it. Runs mostly fine, I haven't been mean to it or drove it hard yet. It still has the bounce when I put in the clutch but no miss anymore so one problem solved

    I called bluechip and chatted for awhile. That man seems to really know his stuff.

     

    I hotwired the vp and it started and idles. So for now I'm ruling out the injection pump 

     

    Doug at bluechip is leaning more toward a throw out bearing or bad pressure plate in the clutch as the cause of the rpm bounce. Since it only bounces when the clutch is in. 

     

    Another cause may be the larger injector. 

     

    Im going to take it for a long drive and see how it acts when it's hot and go from there. Thanks for all the great information everyone
