I just made a check-up, filled up engine oil 0.4L, refilled cooling water about 200ml and filled up disc wiper water… I saw that from the head seal apparently comes out of cooling water at one point, red traces ran down there at the engine block, not much but visible. Can that be at all that comes from the head seal cooling water? Typ89 1.8 PM Built 1990 112.000km What do you think about it? Greeting donki
