RE: My Pete rebuild
With no noticeable soot or fuel dilution, I'll run it another week unless someone here tells me otherwise. I cut the (every) filter open last week and it looked fine.

My security blanket of coming home every night to "fix" emergencies is over now, and I booked myself next week to zig zag down into SC and back. Nothing paid enough to venture to Atlanta area, but really want to make it down so that the pros can either put me at ease, or Mr Hagg can take a hefty deposit haha.

RE: My Pete rebuild
I had no reference on this thing as to how it ran before, what it sounded like, etc., and other than my farm equipment, no diesel experience whatsoever, I missed something that probably should have stood out to me. I know what a Cat 3046 and my little turbo Kubota 'whatever it is' sounds like, but this thing was all new. Is it supposed to sound like that? Or what is the exhaust supposed to smell like? How is it supposed to feel and sound on a hard pull?

Remember, I didn't touch my IFSM at all, and since someone must have replaced all six injectors (date coded 2015), I didn't replace them either. I figured to do the injectors and IFSM, it would have added $8-10k to my build (this was supposed to be a $8-15k total project in the beginning).

Here's the signs I probably missed/dismissed:

1 - On startup/idling it would burn the eyes pretty quickly in the closed garage. (I dismissed this because, well, it puts out a LOT of exhaust compared to my little engines, and my shop is small)
2 - On hard pulls there was a little bit of a "rap rap rap" reverberation from time to time (who knows this may still be there, I haven't put a load on yet today)
3- My dash readout was always a .25+ MPG higher than hand calculations.
4- Exhaust seems to make a lot more soot than it should.
5- A week ago as I was running beside a solid barrier in the left lane, I could hear a knock under load - it was the first time I heard a distinctive knock, and apart from being right next to the concrete barrier I couldn't hear it any other time. I chalked it up to either compressor knock, or my paranoia.

But then when 2/3's of the way up fancy gap when things started to heat up I heard that knock again, only it wasn't faint. After cresting and cooling things off some it wasn't as bad, but any time I was in a pull I could hear it.

At this point, in my mind, I was going to be shopping for a block and eating the core...

Home for a 34, and under a load, I figured I'd check injectors since I didn't have time to handle much anything else. Turns out #6 was bad, and I'm betting that it's been bad all along, just not bad enough to be obvious? Hunter's only had 2, and one looked like it missed QC day at Cummins, otherwise I'd have rather done the back 3 at least... I picked up a set of spare Timing and Fueling actuators just in case - but I simply didn't have time to tear mine down and inspect them - not to mention, I need to find Rawze's videos and do a refresher.

I have a trip to finish today, so we'll see how she does?

Oil is black, so I'm hoping this is the root cause?

RE: My Pete rebuild
Seems to be a real crap shoot with Cummins Remans. I had all 6 injectors done on my 870, so keeping my fingers crossed on those. Have bought all the actuators, but had to warranty 2- one because it was leaking out the "button" on front, and another that has a plug receptacle that didn't like anything being plugged in it. Nothing ever fit right, nor would it lock in place. More like a press fit.

Hope those injectors fix your issues. I still get a noticeable fuel smell from the exhaust every once and while, but am living with it for now.

RE: My Pete rebuild
Well, the engine is MUCH smoother now. Not sure if I should have plugged in the computer and reset anything? But the first hour or so it felt pretty sluggish - but then again I had a few 10% grades to contend with until I got rolling. One thing that amazed me is how it pulls smooth right down to 1100 rpm (I had to try it once just to see). Still has a little bit of a rolling vibration on a hard pull - when I get time, I want to pull apart the actuators and check them. The front metering has been changed out, but the back one still has the o-ring seals and I assume original? Hoping my fuel mileage comes back - the last 3 tanks have been dropping - but then again they've been heavy loads that had the wind drag of a hundred little parachutes...

RE: My Pete rebuild
I'd get my ass down to rawze or haggi for a good visual inspection. It might cost you a little but all that hard work and time/money you put in..... man we would hate to hear n see you blow a head gasket or worse.

Good luck! n safe travels friend.

Waiting for stars to align to do that. I made it as close a Macon, but I don't expect anyone to fit me in with no notice and I already had the next 2 loads booked anyway.

14k on it now, and I'm itching to use the 3rd stage jakes for the first time.

I only did one, and left the other one sitting on the parts counter. I just didn't like the looks of it. It has scoring around the end where it mates/seals in the cup and the bottom lands or rings has corrosion. Plus it had the older style keeper with the big tab and screw - who knows how many times it's been rebuilt, and the last guy at Cummins obviously didn't care about aesthetics, did he care about the important specs inside?
