Difference Between 555 & 6X0

I believe that there are a number of changes, both mechanical and electronic. Different turbo, wastegate, exhaust, pistons, rods, computer controls, etc.

Lots of difference from the 555 engine because of that. Good thing is no EGR like Ford and Chevy, bad thing is worse fuel economy from retarded timing and post injection.
Only going to get worse in January of 2007

The 2004 Cummins 600 Turbo Diesel builds upon this durability with:
In-cylinder combustion and diesel oxidation catalyst solution requires no exhaust gas recirculation components.
Gallery cooled high-strength aluminum pistons for durability and long life to overhaul.
Premium high strength inconel exhaust valves and high-cobalt stellite exhaust valve seats for durability and long life to overhaul.
High strength exhaust manifold with multi-layer gasket between head and manifold.
Forged steel fracture-split connecting rods.
Cummins applied its technology to provide an in-cylinder solution along with a diesel oxidation catalyst. Cummins developed a new piston combustion bowl and a high flow electronically-controlled wastegated turbocharger to better match boost pressure to engine needs to reduce emissions.

The 555 engines had the oil cooled pistons like the 6x0 engines do. That was one of the differences between the SO and the HO engines. I would assume, then, that the rods are the same. I could be wrong, though.

Yes, the pistons are noozle jetted instead of the SO's gallery cooling/lubricating. However, the piston bowl is tailored to the emissions package to avoid the EGR system.
The fracture split rods were actually copied from the D-max. I know, not what you wanted to here, but its true.

Sucks that Cummins is stealing designs from the D-Max, though.

OK, so why does the 610's oil get black so quickly? The 555's didn't have this 'feature'. Anyone know what the engine is doing to build up that soot so quickly in the oil? Maybe if they figured out how to burn this soot we'd get the 555's better miliage.
