Indicator Assembly - Oil Level

The Chevrolet Performance Indicator Assembly Oil Level dipstick (part number 12570788) is the factory replacement stick-only oil level indicator engineered for GM LS-series engines. This steel dipstick assembly provides accurate oil level monitoring and is an essential maintenance component for LS-based engine swaps, performance builds, and stock restorations where precise oil measurement is critical to engine health.

Built from steel construction, this oil level indicator assembly meets OEM specifications for LS-series applications and delivers reliable dipstick accuracy across a range of operating temperatures. The design allows quick, repeatable oil level checks without requiring auxiliary gauges or electronic sensors. Proper oil level monitoring is fundamental to protecting bearing surfaces, hydraulic lifter preload, and overall engine longevity—especially in high-performance or modified applications where oil capacity variations occur due to pan selection, cooling systems, or custom intake manifolds.

This assembly suits builders and technicians restoring LS-series engines to factory specifications, swapping LS powerplants into classic or modern chassis, or rebuilding damaged dipstick tubes. The stick-only configuration allows drop-in replacement into existing tubes without additional fabrication. Measuring 26.65 inches in length and weighing just 0.07 lbs, it integrates seamlessly into OEM and aftermarket engine bay layouts. Whether you're completing a crate engine installation, servicing a performance build, or maintaining an LS-powered vehicle, an accurate oil level indicator is non-negotiable for engine protection and diagnostics.
