DO NOT BORE IT — Check This First!

Save money and avoid unnecessary engine machining. In many cases blue exhaust smoke, high oil consumption, and blow-by are caused by worn piston rings — not a damaged cylinder. In this video I show the exact tests and signs mechanics should use before recommending a bore: compression test, wet compression test, leak-down test, and borescope inspection. I also walk through the repair path: replacing rings + a light cylinder hone and break-in tips.#EngineRepair #PistonRings #CompressionTest
