Engine Strip Down

[Tatey]

Well i decided that i might as well continue stripping down the head today, all thats needed doing was to take the camshaft pulley off, remove the camshaft and take the valves out. I managed to get the camshaft pulley off by making a tool to stop the pulley from rotating and a bit of force from mr breaker bar.

I've taken out the little plate which stops the camshaft from coming out, but now I'm at a loss as to how to remove the camshaft oil seal. I don't want to destroy anything when trying to remove it in order to get the camshaft out.

So does anyone have an idea as to how to remove it?

Cheers
Simon
