Thanks very much for the help guys. I'm going to go to the dealer tomorrow and try and get the bits to do the DV's, hopefully they'll have it all in stock otherwise there is a diesel injection shop I can try.

So, do I risk changing the copper crush washers? The car has 160k and I imagine they've never been done. I would love to do them but after reading a lot of threads I'm worried I'll put it all back together and it'll be worse.
