Hey,

I am replacing the exhaust manifold gaskets on my truck in sig because the 3 of the manifold bolts broke some how. Does anyone know what the Cummins part number is? The stealer wanted $25 a gasket! I just want the the number for a reference when I visit some Cummins shops tomorrow.

Thanks

sorry dude, cant help ya with a cummins part number. I searched google and everything!
I did happen to find a set that BD sells.. i doubt the part # is the same but it could be worth a shot. Also, you could always just give dodge a call and ask them for the #.. i believe it would be the same between them and cummins

Well I got new bolts and the new gaskets but I think my manifold is warped. Cylinders 6,5,4 will bolt up but 3,2,1 are off. 1 is off by half a hole.

Anyone know where to get a exhaust manifold?

The front bolts broke when the exhaust manifold was at normal operating temperature so when the exhaust manifold cooled down, it shrunk. I couldn't get the manifold to expand back out. I tried a exhaust manifold spreader and I also tried heating it up with a torch.
