C15 Head Gasket

[Liendrof]

Hi
I am new to classic bikes, having recently purchased a C15s I have noticed that the head gasket is blowing.
Has anyone got advise and tips for changing it please.

hi its a simple job have a go ,fit a copper one when you change it ...

I started but the first there is only sufficient room for an open ended spanner and it started to slip on the nut

Are you using the right size spanners  WHITWORTH  not AF or Metric

[Liendrof]

Hi
Yes I am using whitworth.

sometimes a metric spanner will be a tighter fit . Ive , in the past , ground a metric spanner to be a tap on fit to get something loose .

Thanks may try that.
Does warming the engine make any difference?

[ducati2242]

heating the actual nut would help but warming the engine may make it even tighter . I would replace those nuts once you get them off .
