   tried to chance the valve stem oil seals in the saxo engine. head is off the block due to changing the headgasket but the bloody springs won't compress with the compressor i have. its a proper one i bought for my cvh head (basically the same set up i.e need longer reach) but for the life of me can't get it to compress, my dad had a go and nothing is do these need to be pressed down? (doubt it but though i'd ask) or its it just they are very very stuck and should just leave them? they didn't smoke but i though whil i got the head off ect
   
   any help would be apreciated

   Mine have always just compressed fine, then you take the retainers off.
   
   Are you sure you're not trying to compress the Valve against itself?

   You've just gotta adjust the compressor.

   injectors just pull out, youll need them out to get the head skimmed
   
   some valve spring compressors dont fit the saxo head properly, mine dont, just got to fuck on, just be carefull, try get them in a position you can get the cap and get your dad to help try get the collets out with a small magnetic screwdriver

   The collets get wedged in the spring retainers. What you need to do is get a socket (around 20mm), fit a 6" extension to the socket, rest the socket centrally on the spring retainer and belt the end of the extension really hard with a hammer. Sounds agressive but it won't cause any damage to the valve components though you may mark the end of the socket extension, so use an old one if you have one. This works every time for me. If you belt it enough you can even release the collets this way!

   the collets are supposed to be wedged in the retainers, this is how they stay in, thats a very silly thing to tell someone who may not have much experience removing valves/springs
   
   have you ever seen one of them come of unexpectedly?

   Yes, they do become wedged, which is why they need releasing by being struck. The leverage offered by the valve spring compressor is insufficient. The alternative is to have an assistant gently strike the end of the compressor which is over the spring retainer whilst force is applied at the lever.

   As said tapp with socket on spring retainer is the method. Releases the 'stiction'
   
   Works for me and have even removed old valve retaining collets this way.

    The gentler non-socket release method I described above is actually given in the 'Haynes Hint' on page 2C.7 of the Haynes book
