500sec bad technique = scrap?

serious people! I am not one of his benz constantly to the customer service or the ding drives, because he doesn’t know where to go with his charcoal… I bought the baby 4 years ago because I had fallen in love since I had consciously seen a w126 coupe for the first time. when I bought my 500er he was already in no top condition and also not in the top price range. however, I have to this day spent a lot of time with the jewelry. after the car now had to stand with defective gear in the open space now I slowly arrived at a point where the whole thing might grow over my head… so as mentioned the gearbox is defective. – replacement gears is already around. then it is absolutely necessary to make the control chain now. moreover he is tearing oil and beside it therefore from the exhaust. – probably the valve shaft seals must be made. and now even wedges must be renewed. to be completely silent of what the mechanics still think about. then he is now ready to take him to the workshop, then he must not give it all to me constructively?
