FEULING OIL PUMP CORP. Gauge Lifter Bore No-Go¢â€žÂ¢ 9004

Precision lifter bore measurement is critical to engine longevity and performance. This Feuling gauge ensures your lifter bores meet exact specifications, preventing premature wear and loss of oil pressure that can compromise your entire valvetrain. Whether you're rebuilding a street engine or preparing a race motor, accurate bore measurement is non-negotiable.

The Gauge Lifter Bore No-Go tool measures both bore diameter and roundness to verify Feuling's recommended clearance specification of 0.001" to 0.0015" between lifter and bore. This precision tolerance window maintains optimal oil film and lifter stability under load. A simple bolt-on verification step that saves expensive rework down the line.
