Omega A 2,6i – Clutch rear bearings

Hello, friends! For 65,000 km already, what’s going on in my backlog when the engine or the gearbox are really hot. There’s no trouble with the dome. Total power is 150,000 km. An acquaintance thinks that he would have driven so 300,000 km without any problems? Who knows what’s going on and how critical can that be or become? As soon as you easily put your foot on the pedal, the sound stops. Do you have to change the backlog? Or is there a Look forward to your advice, heinzbbg.
