Detailed Description

Built for 4-cylinder engines with an 84.80 mm bore, Sealed Power E-923K is engineered around common OE-style ring pack dimensions and standard sizing. The steel moly top ring helps support cylinder sealing and wear resistance, while the grey iron second ring and flex vent oil ring are selected for controlled oil management and consistent ring function in the Ford Focus, Ford Escort, and Mercury Tracer applications listed below. This part cross-references 2M4889 and F7CZ6148AA for the same application.

What It Helps Address

• Excessive oil consumption from worn oil control rings
• Low compression caused by worn or damaged piston rings
• Blow-by from poor cylinder sealing
• Oil fouling from ineffective ring sealing and oil control
• Compression loss during engine rebuild or overhaul work

Installation Notes and Tips

Verify bore diameter, ring groove widths, and standard-size requirements before installation. This set is not file fit, so ring end gaps should be checked against the engine builder’s specifications during assembly. Confirm cylinder condition, piston groove cleanliness, and ring orientation before final engine assembly. Fits 2000-2004 Ford Focus, N/A; fits 1997-2002 Ford Escort, N/A; fits 1997-1999 Mercury Tracer, N/A.
