Overview

The Performance Tool W89729 is a leakdown test kit designed to diagnose internal gas engine issues such as worn piston rings, faulty valves, or leaking head gaskets. This kit offers more accurate results than a standard compression test by applying pressurized air to the cylinders and monitoring leakage levels.

It features dual 2-1/2 inch gauges with chrome bezels and protective boots. The compression gauge ranges from 0-140 PSI (0-10 bar), and the leakage gauge measures from 0-100 percent. The kit includes a pressure-regulated manifold, quick couplers, and a 24-inch long 14mm flex hose. It also comes with 10mm, 12mm, and 18mm threaded adapters to ensure compatibility with most gas engines. All components are organized in a rugged blow-molded storage case with a removable lid.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
