Part 1: Diagnosing Loud Knocking in Volvo TWD121 Diesel Engine
In this video, I investigate a severe knocking noise coming from a Volvo TWD121 stationary 6-cylinder diesel engine. The engine exhibited a loud knock, and I suspected internal mechanical failure.(the exhaust valve was broken then the piston smashing the pieces that causing a loud worst knocking sound) Watch as I carefully disassemble and inspect the engine to identify the exact source of the knocking sound.
🔧 This is a real-world diagnostic process where I uncover the true cause of engine knock – and I get it right! Whether you're a diesel mechanic, engine enthusiast, or working on Volvo industrial engines, this content will help you learn how to approach such problems.
👉 Part 2 (coming soon): Reassembling and testing the engine after the repair.
