And if it's one of the newest ones, it no longer sounds like it's Cummins apart....
There is much to be said for high pressure injection... sure quieted those Cummins' down!
Quiet diesels suck.
The reason they are now quiet is becuase they went to overhead cams.
The older V8 diesels in the GM and Fords rattled the same. The problem with V8s is that if you let them idle for a extended period they tend to mess with the intake manifold because they tend to cool and things like that. Then the torque on a V8 isnt good. I mean they get torque, but it takes two extra cylinders to get it.
I'll take an inline over a V8 any day...gas or diesel.
