Coach: 1998 Country Coach Magna w/ DD Series 40 engine
Date: May 2008
Location: US67 near Cleburne Texas
Problem: Engine lost power and began to smoke very badly. Smoke was white. Engine continued to run at idle but had no power. Any increase in RPM generated hugh volumes of smoke.
Resolution: Had coach towed to local diesel engine facility. They diagnosed problem as failed turbo. Replaced turbo, replaced all injectors and changed oil and filter. Problem resolved but at major cost.
Cause: Coach sat for extended time in early 2000,s and turbo was evidently rusted from lack of use. I purchased vehicle in 2005 and had driven it regularly since then for 15K miles. Failure happened at 47K miles.
