Great engines and wet sleeve cylinders, so rebuildable. Make sure to remove and service the heat exchanger and aftercooler every 2-3 years. Not a horrible job. Stay after the zincs on these as well. Switch the stock raw water pump to an SMX.
As others have said refer to the excellent resources and products from Tony Athens at SBMAR.com
Some good you tube videos on these as well...
