my astra 1.6 16v ecotec is useing water there is some water in the oil but not a lot (am puting about 4-6 lts in a week )
no water visable under car . also how do i change the head gasket
Water in the oil usually results in a creamy 'mayonaise' like substance in the rocker box. Any water in the oil usually means a head gasket job. To see how easy/difficult this is I suggest you buy a Haynes manual.
