I have a 1.6 diesel, mechanical 12mm head. I was wonding if anyone has replaced just one head bolt without removing the head or replacing the head gasket? When I put the head on this engine everything torqued correctly but when I did the retorque the rear bolt on the passanger side was pretty easy to turn compaired to the rest. Now it is leaking a little bit of oil from the head gaket on that corner.
So can I just replace that bolt or should I just live with it?
