"Nettoyage des cylindres sur moteur PURETECH : le résultat m’a bluffé ! 😳" (Feat TUNAP 133)

In this video, I'll show you the professional method for restoring compression to a PureTech engine through a complete internal cylinder cleaning without disassembly, using the TUNAP 133. The 1.2 PureTech engine is known for its timing belt problem; the belt disintegrates, clogging the oil strainer, as well as the combustion chambers, valves, and piston rings, leading to a loss of power, excessive oil consumption, and reduced compression. Here, I'm performing targeted internal carbon cleaning: cylinder and combustion chamber cleaning. What you'll learn 👇 🔧 Symptoms of a dirty PURETECH engine (loss of compression, oil leaks, misfires) 🧴 Internal cleaning with TUNAP 133 + TUNAP 955 oil protection ⚙️ Before/after results: compression, performance, reliability This method is ideal for extending the lifespan of the 1.2 PURETECH engine, reducing belt-related deposits, limiting internal wear, and restoring a healthy engine.
