I found what looks like a rebuilt 4.7 HO V8 engine at Pic-a-Part from a 04 Jeep Grand Cherokee Limited. After removing the camshafts I noticed that the cam gears and timing chains were like new and after looking at the engine block I realized that the engine looks to be rebuilt recently. To find out the condition of this engine I'll show you how to perform a cylinder leak down test. I also do a comparison of the Harbor Freight US General 94190 to the OTC Cylinder Leakage Tester Kit.
OTC's Cylinder Leakage Tester Kit quickly diagnoses internal engine problems like bad rings, valves, and leaking head gaskets and comes complete with adapters for most applications
Dual 2-1/2 inch gauges read 0-100 psi.
Kit features a pressure-regulated manifold with quick couplers, 24 inches long 14mm flex hose, and 10 mm, 12 mm, and 18 mm thread adapters. amzn.to/3EjCkxI
