John, are you having issues with your exhaust leaking? Is there a specific question that someone can answer? Welcome to irv2, by the way.

John, welcome. You should post this question on the Cummins owner forum. Many helpful folks there with great information.

ISC or ISL ? My ISC manifold cracked and had to be replaced. Apparently it is a common problem along with gaskets and broken studs.

The ISC engine does not come in a 400 hp version. If you have a 400, it is an ISL. If it is an ISC, it is somewhere in the 330-380 hp range, depending on year and engine configuration.
