I suppose i could just try a metal type one again, i think its not sealing because its crushed too much, it was a new one but i think we must have tightened the turbo up at a dodgy angle an its crushed it up. I was after a copper one as they wont deform an i suppose can be re-used! I didn't mean actual paper type, its the type that are solid material but dont crush, i have one on my downpipe to ehxuast that came with my nur spec.
I'll get a toyota one then and see how that goes, won't be fitting it till the other turbo arrives but hopefully it will seal properly this time when i do it myself!
