[C320-list] Heat Exchanger Removal - Perkins M30

[appleton1 at yahoo.com]

While you’re at it, disconnect the mixing elbow from the exhaust manifold and check for internal rust.
The part is a heavy casting and, unlike those on lesser engines, will not rust through but rather rust internally, to the point that it chokes the engine. The 2-in.-dia. port to the muffler becomes 1/8 in. dia., or smaller!
Ask me how I know...

I would like to remove my heat exchanger and clean it. Additionally, my plan is to soak it in a 5 gallon bucket using barnacle buster or something similar. Any thoughts on that, as well? Are there other alternatives that work well that are less expensive?
