Re: Exhaust manifold Reply #29 – May 09, 2022, 05:18:38 pm Ran 350 miles, boost back to 26-28 lbs at WOT, hottest I saw the manifold get was 600°. Looks like the JB weld material worked/ with beer can back up. Quote Selected 6 Likes

Re: Exhaust manifold Reply #33 – May 11, 2022, 09:26:15 pm Ran 250 miles today setting all kinds of crazy codes, but running perfect. Engine speed, several invalid entries, injector driver codes.Oh well fix the manifold first and go from there. Got 250 more to go. 😬🍺 Quote Selected 3 Likes

Re: Exhaust manifold Reply #35 – May 11, 2022, 09:55:17 pm Did before I field repaired it, then ran great 350 miles. Still running great getting 8.9 mpg pulling the Jeep. Repair looks to be holding ok. Quote Selected 4 Likes
Re: Exhaust manifold Reply #36 – May 13, 2022, 02:58:52 pm We'll made it 750 miles. Coach ran great, but setting a bunch of odd codes. One thing at a time exhaust comes apart tomorrow, we'll see what we get into. Quote Selected 7 Likes

Re: Exhaust manifold Reply #40 – May 14, 2022, 02:36:17 pm Got everything disassembled, no broken bolts. Did find the oil line rubbed a hole in the wastegate actuator. I expect that will be fun to find. Quote Selected 5 Likes

Same break.Also had to pull, machine and reinstall the exhaust manifold on our Caterpillar engine due to warpage.Just not that uncommon an issue. I suspect (no statistics on it) that the rear engine instead of the front engine where there is ample air flow adds to the likelihood of failure. Quote Selected 2 Likes
Re: Exhaust manifold Reply #43 – May 14, 2022, 03:01:27 pm I replaced my wastegate actuator years ago because of a bad internal diaphragm. Call Cummins with engine serial number and go from there. Seems to be many sources online. Quote Selected 1 Likes

Welding the cast manifold I agree no joy. The actuator housing is mild steel and if you keep welding temperature and duration limited its quite repairable, but I still would prefer to replace with a fresh component. My luck 2k miles down the road it fails and your in there doing it again. Scott Quote Selected 1 Likes

Re: Exhaust manifold Reply #48 – May 16, 2022, 08:32:00 am Any theories on what would cause the exhaust manifold to break cleanly apart like that? It's seemingly pretty stout material, so I would think not too easy to snap in half.Perhaps caused by unequal torque applied to the mounting points, so the manifold is under constant stress. Add to that the repeated heating and cooling cycles. I can't see vibration being a factor, cuz the manifold doesn't normally "move around".Or, is it a flaw in the casting. I know nothing about metallurgy, so I'm clueless...but also curious.Google says one theory is the weight of the turbo assembly hanging on the manifold is too much stress?Also, anybody ever used Kroil? I'm just filing away pertinent info for possible future projects.Kroil - Best Penetrating Oil | Kano Laboratories, LLC Quote Selected
