Hello, dear Audi friends… On Tuesday I wanted to do a super cleaning of my Audi 80 B4 ABT 90PS built in 1994… That’s why I wanted to do an engine wash and renew a few small things on the car. There would be the valve cover seal. Now my question: 1: How do the screws have to be tightened? (see picture ?) 2: With how much Nm do the screws have to be tightened? Thank you nicely in advance Greetings from the sunny Black Forest Matze
