Hey,

I'm doing the valve seals at the moment on my A12 and just realized that there is nothing to stop them staying on the head?!

I was under the impression that they stayed on the head and the valve slid through the seal but now they kind of look like they stay on the valve stem and kinda of reciprocate with it and act like a shorud to stop oil getting down the valve stem?

FYI my new valve stem seals look just like my old ones which are a domed black piece of rubber with a hole through it.

Am I missing something or is that how they are meant to run (fixed to the stem)?!
