Longacre Leak Down Tester 52-73010

A leak down test is essential diagnostic work that tells you exactly where compression is escaping in your engine—information you can't get from a standard compression check. The Longacre 52-73010 gives you dual gauges to measure both the air pressure you're applying and the percentage of leakage simultaneously, eliminating guesswork and letting you pinpoint valve, ring, or gasket issues before they become catastrophic failures. Whether you're troubleshooting a tired engine or validating a fresh build before it hits the track, this mechanical tester delivers the straightforward data you need to make informed decisions.
