> rings, since the performance of the thing went from good to bad within a
> day. Running bad, missing, lots of blue smoke, and starting hard.
> pump and cam timing, all in spec.
> What could cause piston rings on a 1980 Dasher diesel to go bad? The
> engine has 85,000 miles on it since rebuild (which included new over size
> Mahle pistons, rings and such). Could it be something else?
