I tend to reuse them a couple of times although after my trip out at the weekend (200miles) I have a significant leak and hoping it's the rocker gasket!! I'll fit a new one this time
I over filled the oil yesterday. I hoped if I ran it a bit the level would magically go down. When it didn't, I'd had enough so it's still 1/2" over the mark. That's gash, I'll have to let some out before I go anywhere.
