Okay, thanks for the help so far. I'm not the owner,the car is from a friend ( 83 years old now and not a computer guy)who restored en rebuild the car as new a few years ago. (ten years of his life) When he started restoration the chassis and the engine where rebuild by the previous owner and that's now the problem. Don't trust the job from people you don't know ! The rebuild of the engine wasn't done correct .Now an overhaul company has measured the engine and made a rapport from that work. (costs €2000!) and they're asking €35000 when they repair it. Now the engine is back home and we are looking for a company that can fix the job for a normal price.
