Moin, I looked under the hood during the oil change and had to examine various defects. Since I still wait for my repair instruction and hardly know myself with the inner life, I hope that here some experienced experts give their comments to my pictures and could possibly call me helpful or important steps, which is bad, what to do or how expensive or how elaborate etc. etc.Audi 90 photo album Especially interested me, where the slag on Bi ld 014 comes here. Is it normal, that with the starter on picture 008 only a pole is connected? Why the heat jacket? Oil pan has superficial rust.. can one pull that off perhaps with hammerware? Should be airtight. The timing belt looks still good for its almost 6 years and 7,500km, not porous etc. Garage trolley stop. The stains on the tub from the coolant on picture 031/032 are old, so dried. Image 016 shows such a preservative, so the then often the Cavities sealed and thus not saved. Thanks already for all comments.
