Woah! Peace on this place guys! Like hearding cats, the rule is be carful, keep checking amd try to avoid the scratches.
So if it's just tight and don't leack that's a good start? A regular bit of servicing used to be De - Coking, how often do you need to do that now? We think a head gasket should last for a 100,000 miles, the old guys thought in terms in 20,ooo or less.
