I'm an administrator on another forum where I dis-abled attachments, pictures can only be loaded with Photobucket or Imageshack or other photo hosting sites using the "INSERT IMAGE" clicky, that way the server doesn't get full of photo attachments, only the links to the host.

... but it is pretty big!

I don't mind hosting all the attachments - it just doesn't make sense to allow megapix when we are all looking at them at 72dpi (or thereabouts)

This is the cylinder head from my K0, hope it identifys yours, any one out there know of anybody who can repair a hole going down from the cam carrier stud , yonks ago i had a helicoil done and the twerps drilledight thro to above the spark plug and when i refitted the head got a constant leak from there hence why i got another head and fitted that not sure what K it came off but seems to run ok. Any way love the forum and its been most helpfull.
