Hello have there a question what costs a change of the head seal at an audio80 bj.1991 1,6l 70ps. have there white mud on the oil filler, it can also come from that the car is moved on the day only approx.5km and that already for about 8 months,ch mene there is also lack of water in the cooling tank, but the hoses also get really hard,if he is warm driven.I paid for the car only 700,-euro, since then I did not want to know what to pay for repair costs.
