Valve stem oil seal replacement (head-on)

[umpkin]

looks like i may have to do this as well as the new turbo, thank fully once i got the turbo off, i could feel it has lots of play, so im confident i havnt spent that money for nothing,

but apon checking, i have found oil running down one of the valves, possibly 2, cant see inlet side, i have a set of stem seal already in a HG kits i got for the rocker cover gasket.

so i can get some rope or similar, what i need is a spring compressor, what did you use, is there a part i can buy to do this for me, like the ones you used to get for the ford pinto engine, although they used compressed air in the plug hole.
