I haven't been making family vids of Stinky lately... he was being a brat again. I found the issue and Stinky's behaving, with just the littlest bit of post-whack sobbing.

I had to swap a knocking injector - but don't assume the injector went bad on it's own. I'm exploring something that the truck (or I) might have done to the injector. My 9th injector is now in the hole, and it needs to be "broke in"... so it makes just a little more noise than the others until that time.

Anyway, this is vid a bump from 50 MPH to 70 MPH:

 

Rich - jsut for my own education what temps are you measuring with the two left pyro meters?

Thanks

 

Driver manifold on left, passenger manifold on right. The probes are just before the up pipes.

Here is a photo of the driver-side probe (behind the orange connector in foreground).

 

Rich a little off topic but as one of our resident experts I thought I'd ask. My Ex is 100% stock are EGT's something I need to worry about, I tow a 7000lb travel trailer. I had money budgeted for an infinity but I spent my money on a hensley hitch. I could probably get the wife to approve an EGT gauge at this point but definitely not the infinity I was planning on getting.

Thanks

 

Chiming in on this - I towed my 13.5k lb 5th wheel all over the southeast, including the mountains of NC and TN, in stock form and couldn't ever make my EGT's go over about 1200. As long as your truck is healthy, you should be fine. That being said, I still reccomend getting some gauges, because they can be a good indication of a problem, i.e. transmission overheating, leaky uppipes, boost leaks.

 

Thanks Bob, I'm using torque so I'm able to monitor boost and transmission temp. I still plan on getting the infinity it's just been pushed back some I HOPE to have it before my trip out west this summer.

 

I find it interesting that the left EGT starts lower but climbs faster than the right.

 

I dont. Firing order.....

6 and 8 fire back to back....faster heat build up right there.

 

Is it lost on anyone that Tugly just popped a VC? Again? Faster than a Fresca?

 

I bet he could have a injector out the same time for me to pull my AIS air filter element.

 

Soo... Any ideas what caused this injector to go bad?

Yeah, this still makes me shake my head.....he talks about popping the VC off and doing this or that like me changing my oil......sadly he would have my injectors off in the time I drain the pan........

 

Following Robert6401's sage advice, our trucks are getting older. You no longer have a "stock" truck, you have an unmodified used diesel with a lot of zeros on the odo, and years in the world. Gauges are a good idea for these trucks out of the factory - IH puts them on rigs with this engine.

They do all kinds of weird things with speed and where they land... but they are never more than about 50 degrees apart. There are too many factors at play - direction and temperature of wind, programming and tolerances of the gauge, differences in the probes, depth of the probes, firing order, etc.... Ultimately, I'm looking for significant differences, because a troubled injector is not subtle on the pyro. I got tired of using the hand-held laser thermometer, and I knew as soon as I invested time and money into the second pyro, my sticks would settle down. You know, "watched pot" and all. Now I need a What-the-Hell-is-Nextometer.

It was lost on me. It was muscle memory, and I didn't even realize I did it.

This trip into the VC was the silver bullet. I found something small, yet profound. I'm trying to do a write-up on it (complete with photos), but I'm being interrupted with my regularly-scheduled disasters at work and home.

Early release: It wasn't Full Force Diesel's fault. As is the case in many scenarios, it was a diesel enthusiast missing a detail and causing great grief for himself.

 

hey Tug...was there enough of a lead or was there just enough, of a lead after a pre-determined path, with the p/s pyro lead?

 

I ran the cable out through the passenger footwell - there is a hole with a rubber grommet just sitting there. I had plenty of cable for a "service loop", but my gauges are in the middle-lower part of the dash. If I had an A-pillar, that might be a more "interesting" cable run.
