Maybe someone makes a good aftermarket EGR valve, but I'd be wary of it.

2014pinnacle Posted 6 hours ago Author Share Posted 6 hours ago I just got my truck back together today we had to relate the the valve and the manifold broke bolts off getting egr off. The truck is back together and it sounds like a giant vacuum cleaner any thoughts on what it might be? It sounds fine for about a minute and then it makes like a high pitch vacuum noise I can’t find any leaks anywhere. I dont have a scan tool what kind of things would I see if the vgt turbo is stuck?

The Heinz Posted 6 hours ago Share Posted 6 hours ago EGR hot pipe probably isn't seated well, it's an absolute pain to get it correct. It's always recommended to replace the gaskets at the minimum when you pull it off, it's that much of a pain.
