I have an old 1960 GMC converted to a motorhome. It has a later model turbocharged 671 Detroit Diesel. It runs excellent, but the other day when we serviced it and ran it from the rear, as we shut it down we heard a jingle coming from the engine. As hard as we tried, we couldn't locate the jingle. A call to Penske gave us a heads up to maybe the turbo. It runs so excellent otherwise. The turbo looks like no fun to change. Also, it doesn't sound like it coming from the turbo. Has anybody ever worked on one of these? |
