does failed cranks and blocks ring a bell? converting an olds gas burner to a diesel didnt work well for GM, but again, what has worked well for them?

Our church has started the discussion about selling our mini-bus that is built on a 1997 Chevy G3500 chassis with the 6.5L turbo diesel engine.

The 6.5L is not a bad engine but it does have it's issues. Among them are cracked blocks and broken cranks. Not all of them but a lot of them die well before 200,000 miles.

The issue for our church is we have found it increasingly difficult to find parts and pieces that are specific to the G-series platform.

The 6.5L was not a very popular option in the G-series platform. As a consequence there is virtually zero support for the application in the aftermarket. The aftermarket is needed because when GM stopped production of the engine they also stopped making spare parts. Now that the GM parts supply has been exhausted some of the parts and pieces are simply not available anywhere.

The 6.5L was put into many trucks and HUMVEES so there is aftermarket support for those applications.

My recommendation would be to not consider any bus, particularly a bus built on the GM G-series chassis, that has a 6.5L diesel engine in it.

Don't make the mistake of getting a one ton van cutaway bus.

Your better off with a short, full size chassis bus. Much better engine choices, better brakes, ect.
