Hello my dear car lovers! I bought a KIA Ceed 1.6 cvvt about 4 months ago. When buying this 99,000km now it is 105000km. The purchase took place by private. The car was converted to auto gas at about 30,000. At a spontaneous check under the bonnet a few weeks ago I noticed the following: – at first the cooling water tank was almost empty – on the oil cap a brown / yellowish slime formed – and also on the oil measuring rod is this Schle In the to find a huge shock for me, because that means that cooling water enters the combustion chamber and thus either the cylinder head seal or the head itself leaks. I have also been able to observe the following and maybe this tells one or the other of you what => – the cooling water always falls to the same level and does not sink further afterwards. I have always refilled it at the beginning now I do not do this anymore, since engine temperature always fits! – The temperature flow There is no wise smoke when the engine is running – a power drop can hardly be felt you can easily drive 160 A workshop bill was available for purchase: – control chain was exchanged at 97,000km – cylinder head seal was exchanged at 97,000 – both in July 2015 Now to my questions: – What do you think it could be? Already the cylinder head seal again? Or the cylinder head? – How expensive would the repairs be? I’m pretty sure he already knew this when he was selling it!!! Maybe by asking the workshop that had repaired the cylinder head seal? This whole story hits me financially really hard and I am also dependent on the car every day for the drive to work, so I’m for everyone. on your part open and very grateful!!! Maybe you also have a workshop recommendation for the room Hamburg? Also without invoice Thank you for your answers!
