I have a cracked exhaust manifold on my Volvo 3.0GLP-A. It is on the bottom between the plug and the water drain. It runs about 6-8". I knew that there could be a potential problem due to improper winterizing. I discovered the crack after running the engine (with a hose connected to the engine flush) for about 1 minute. This was the first time after the winter. I inspected the engine and immediately found water leaking from the manifold. I purchased a small mirror, ran the engine for 30 seconds, and then inspected the damage. The water that first came out was rusty. One of the nuts / bolts on the end of the manifold is rusty.
I know I'm screwed, but would appreciate some insight on what happens next. What parts of the engine can water stand in when stored (obviously the manifold is one)? I would assume the Cylinder block is another, based on forum posts. Can I replace just the manifold and run a diagnostic to determine if other damage exists? Should I just have all potentially damaged parts replaced? If yes, by whom and what kind of expense am I looking at? Are there any web sites that can give me more extensive information about the operation of marine I/O engines and their cooling.
Thank you, in advance, to all of you who reply and share some of your knowledge with someone who really needs it.
