Alfa 145 engine damage ???

Hey people driving the 2 liter 145 150 hp bjh. 96. Yesterday on the autobahn something hops went definitely at 160 kmh a loud noise from the engine then he for a while no gas accepted and then he went out πŸ™ well, timing belt is not the one that was changed recently also only 70000 km on it of the adac means that it might have torn off a valve but is that really possible ????? Well on every case on the evening he didn’t go at all today morning had I tried it again there he once 3-4 sec jumped but sounds like a tractor!!!! Does anyone have any experience what this can be ??? I’m still lucky that I still have a used car yarnie… drive the dear piece only two months ago!! On Monday he comes to the workshop however it doesn’t let me rest would have liked to tear down the valve cover today !!!!!! πŸ™‚ The funny thing is that so far he had no problems just that he might have a little bit much ΓΆ I swallowed!!! Well, one of you knows very well ….. Thank you very much
