Clip #2 of idling after around 50 minutes of driving mixed highway and city traffic.

 

I sucked it up, put everything back together and took her for a drive on a 55mph highway close to the house and did a couple little laps. Boy was it embarrassing at first, so much white smoke and I was very uneasy about how rough the truck was running. I tried to keep the rpm’s up for a while and the first time I got off the highway I could immediately hear injector noise coming to a stop that I know is what it’s supposed to sound like, crisp injector “clatter” with no skips in the firing. It started driving much much better. Eventually the white smoke was no longer there. I took a 50 minute or so drive, got a little bit of everything in as far as driving type, and I drove it on the hard side. Much much less shaking although there’s still some but maybe closer to normal? I also changed the oil and took a sample before firing up the truck with the new injectors. Regarding exhaust manifold temps, after that first drive they are all pretty close to eachother, ~20 degrees with the rear being hotter usually I think.

 

Just got back to the house where I could listen to your audio. Sounds like some fuel knock, likely from air in the system.

Sounds like you've got her on the ropes now though. Maybe a couple minor bugs left?

 

LOL tell me you are out in the sticks w/o telling me you are out in the sticks!

That sounds pretty good to me given the drive cycle stated. If you want to pursue it I'd think maybe some air in fuel.

 

Dude I've lost count of how many soldering irons I've tried or killed over the last 5 years. I've tried cheapo's, and not so cheapo's. I've tried butane, corded, power stations, and even a battery powered Weller POS and they all fell short in one way or another. I'll take my home built ghetto fabulous Powerstroke soldering iron hands down every time. Plus now I can make custom tips for welding plastic in minutes for pennies.

That sounds like a good possibility. I started the truck yesterday and let it run a bit to mainly make sure my batteries held a charge after and I don’t know if my ears were clogged but I believe it sounded even better (less knock intensity) with a smooth and shake free idle. Even high idle was smooth and it started to shake pretty good @1,000 rpm before and smoothed out over 1,200. Now it’s smooth from 500 to 2,900.
I took a video for my own reference and I think I can hear some fuel knock still but it sounds like how I’ve wanted it to since I bought it, like a school bus.

I did a data log on Friday on my post injector, drive it like you hate it drive and saw icp 2,800-2,900 so I’m hoping that points to the oil side functioning well enough. Air in the fuel is my next diagnostic goal, might call around and see if anyone has the parts ready for pressure testing that could let me pay to rent in the parking lot.

I’m also curious if the hutch mod could cure the rest of my currents woes so I can move on to dropping the truck at the transmission shop $$$

 

All you need for fuel pressure test is some 5/16 hose, a 100# gauge, a hose barb the fits the hose and gauge, and a couple clamps. Put the hose on the bowl drain valve with a clamp. Then gauge and barb on the other end with a clamp and open the valve. To check for airm before putting the gauge on the hose put it a clear jug and cycle the key. Any bubbles show up in the jug then you sucking air somewhere.
