Piston Rings
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Ford Pickup, 2001 Ford Expedition, 2001 Ford Econoline, 2000 Ford Pickup, and 2000 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
Ensure ring end gap and side clearance are within specification. See PISTONS, PINS & RINGS table under ENGINE SPECIFICATIONS. Position oil control ring expander with gap positioned straight forward and rails with gaps 180 degrees apart, aligned with piston pin. Install compression rings with gaps staggered, so ring gaps do not align.
