hi i have just brought a astra 1.4 and have just noticed that the oil cap has mayo under it and so does the oil sump, i also noticed that the water expansion bottle was empty, does this mean that the head gaskets gone or could it be other things, i have read that having these symptoms on an astra doesnt nessary mean that the gasket is gone, please can someone help, i am now going to monitor the water level and see if it goes down.
also is changing the head gasket an easy job or not thanks
