Don't worry Anth, I posted to give a few folks a laugh at my misfortune. I'm just so bloody annoyed that I didn't put something like copper slip on myself, what a dozy Twit.
I've got another set in the garage that I could drop on right away, I'm just mindful of what Stick said. They put those cheap plakky ones on for a reason
Any idea on what a valve replacement should set me back ?
