Dealing with some smoke and high EGT issues on my recently installed 1HD-T (install is documented further here), I thought I would baseline some things to see if the issue would resolve itself. That, and I've been sorely disappointed by the performance of this thing. It doesn't really have much more pull than my 1hz did after I first rebuilt it - even after I replaced the stock turbo and put my rebuilt Grunter back on (though that did make a big difference).
Given the above symptoms and knowing the compression is 475 across and there is zero blow-by at idle, I'm getting after two things first:
1. Checking the pump timing (just got the tools in to do this, hopefully ), especially since I pulled off the ACSD.
2. Pulling the injectors and testing them since they were in unknown condition with potentially around 145k km on them.
I suspected the injectors correctly by the looks of it. They were an absolute beast to get out. This is the best looking of the 6. I could barely make out all the nozzle holes. Sorry for the poor photo quality.
I should've snapped some photos of the bodies, but you get the idea of how rough they looked based on this I'm sure.
Here's how they tested. Not awesome, which given how it was running, is awesome! Simple solution. Expensive though!
Just picked them up today and here's what I ended up with.
Those guys at Diesel Fuel Injection Service are the best and I highly recommend them. For reference, a rebuilt set of these with new nozzles ran me around $560.
Next is to take my newly purchased gun cleaning kit and vacuum the carbon and rust out of the injector holes. Then we'll see what difference these make!
