Does the 2000 E 350 have any major problems especially related to pistons?
They do seem to have a tendency toward "piston slap" until the engine is warm. That's where the bottom skirt of the piston wears a little and becomes small enough to rock a couple thousandths of an inch at the bottom of the stroke. When the piston rocks quickly it makes a sound that is characteristic of piston slap. That's the bad news. The good news is, the engine can run several hundred thousand miles with piston slap and as long as it goes away when the engine warms up... no problem. It's more of an annoyance than anything. But If you insist, you can have the engine rebuilt, spend a lot of money and MAYBE it will all clear up.
