Re: Exhaust manifold Reply #51 – May 16, 2022, 09:35:19 am Quote from: Chuck & Jeannie – May 16, 2022, 08:32:00 amAny 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, LLCCast iron parts just dont have a permanent life unlike ductle iron. Much less production costs and reasonable life make it a good product all in all. Lots of heat cycles and the weak point will always present itself eventually. Scott Quote Selected

I also made it a point when ever possible to assign them there own prior work. Eventually it made sense to them what a difference it made. One comes apart and one is fused together never to separate till complete failure of the bolt. Chris is correct 100% IMO.Scott Quote Selected 1 Likes
Re: Exhaust manifold Reply #59 – May 17, 2022, 04:44:54 pm Quote from: zmpm01 – May 17, 2022, 02:24:15 pmMr. bbeane, What gave the broken exhaust manifold away? A typical exhaust leaking sound?? Thanks for the info. Mike A couple of things. I do a pretty good check over before startup every travel day noticed a little soot around the turbo thought I had a bad gasket. Once we left all kinds of crazy engine codes, and my Silverleaf indicated lower than normal boost pressure. So a closer inspection it was kind of hard to see with all the turbo plumbing in the way. I replaced some engine sensors last summer, in 12k mile have no check engine lights. So I'm going to assume that between the broken manifold and the hole in the wastegate actuator it was causing some conflicting signals to the ECM. We'll see when I get things back together.
