Cummins ISL Exhaust Manifold and Turbo Replacement

[zmotorsports]

In this video I show how to replace an exhaust manifold and turbo on a Cummins ISL engine in a Monaco coach on Roadmaster S-Series chassis.  The early Cummins ISL engines are known to break fasteners or worse, have the exhaust manifold crack and/or break.  While turbo issues are less common, I show how to inspect, and replace necessary and you are already in there for other repairs.

Maybe off topic a little, but I have a 2006 Monaco Cayman 36PDQ with a cracked exhaust manifold.  The engine is a Cummins 359ISB, manifold part number 3955199.  The shop where I've taken it for repair is telling me that there is about a 6 month back order on the manifold after checking with all their suppliers.  Does anyone know of a source for parts, even used, that I might try.  I really stuck if I can't get this thing fixed any sooner than 6 months!
