[C320-list] Heat Exchanger Removal - Perkins M30

[BILL CARR]

 I can attest to the importance of a free flowing exhaust system. I replaced my Perkins with a new Volvo due to the elbow restriction causing damage to  my M30 with only 1100 hours. I love the performance of the new Volvo however I would have preferred not paying for a repower.

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?
