Both Robert and Dave were active members of a forum, and there were threads to help deal with the problems. Both situations were out of the normal thread discussions trying to solve the issues, although forum discussions often miss some of the details like being there. People who wrench on these every day may have caught Roberts's cause, but HFCMs having the fuel heaters active is on the rarer scale. Dave's I'm not seen before, and I've been active on diesel forums since 2001. But I thought these would be interesting to view, and I was committed to finding the cause.
Jack, thank you for another outstanding production. Although I didn't mind the female narration, I hope you get better soon and return to the voiceovers. Your Grilled Cheese Buddy :)
Once again, an incredible in-depth analysis with well documented data. Between you, and other 6.0 enthusiast channels (Rip Diesel Tech Ron) I am able to understand my 6.0 and hope to keep it for life. 🙏
Yeah, @toomanytoys is a great legacy to what DieselTechRon started and a natural (r)evolutionary step forward in understanding not just how this platform works but also general principles in (diesel) vehicle maintenance.
Excellent movie as usually, Jacqueline. 😉 😂 The blockage was very interesting and pretty extreme. I wouldn't of expected to find that. Also on the images of my old pump motor terminals, Do they appear like they got hot to you based on the color of the copper? By chance did you ohm the terminal strip to pin? I wonder if there was a poor connection. When or if you're ready, let me know when you want my heads for analysis.
Every once in a while you have to get in touch with your feminine side. LOL. It was just the most realistic sounding voice of the choices, and I thought it would be interesting to see the reactions to it - replacing me, and for a diesel category. I had thought about the coloration of the copper leads, but I don't have a good handle on the oxidation that would occur over these years of copper just being in diesel fuel. When I checked the pumps, they only pull around 5 amps at 60psi. And the diesel flowing through should have a tremendous amount of cooling. Usually I think about checking those heads every time I go down to see my doc. We should just plan a date when its convenient for you. I was thinking of mapping the cupping of the surface with straightedges, and checking the surface finish in the areas that are not in contact with the gasket. I could do that down there - you have my cell/text #.
Even those pump systems will have problems with debris in the line fittings . Nothing beats checking to see if the lines and fittings are actually open, from the tank to the filter, when there is a question of pump pressure or flow
