Any engine will self destruct in a similar way if the valves are bad enough out of spec, no mater what brand.

 

 

Well shes up and running again, went the cheaper route and got a motor out of a burned up truck (cab fire) and swapped over what we could and got it back in. The truck will be makin its maiden run done the track on sat. I'll be sure to get a vid...

 

correct me if im wrong but dont the duramax's like the power stroke's do not have adjustable valves, they are hydraulic tappets which hydraulically make the correct valve lash... i know there not adjustable so i don't see how you can have a bad valve adjustment with them. looks like the old engine may have dropped a valve seat? Do the aluminum heads have steel inserts on the exhaust side?

P.S. Cummins is the only engine (out of dodge chevy and ford) that has a mechanical adjustment. But like i said correct me if im wrong

 

there adjustable.

 

seems like i have some pics pretty close to those. sucks it happened, but glad its running again

 

thats pretty crazy, so many chucks of metal. good to hear its up and running too at least this time it will be adjusted correctly

 

ouch better than a 12v

 

good to learn something new, all all years adjustable?

 

yes. the valve lash on them is .012", when i did mine they were past .036
