Hallo Guy's just an update, I was at revo on saterday and look at the software and said that everything looks okay. So we spoke about the history of the motor and wat was done. When the head was at the I engineering shop they did a valve job new valves and guides, titanium valve springs and so on. Now my question is. They skimmed my head and now my compression is higher then std. Revo said this can be why the car is pinging and segested 2 head gasgets. I know they only skimmed the head slightly and deck the blok just to make sure everything is straight. I really need your help now and don't want to open the engine again if it is not nessaserry. I do have 3 other std heads. My vcds is showing error codes knock sensor out of range signal to high
