 7M-GTE - Changing Valve Stem Seals

Hi guys,
I'm a bit of a procrastinator and think its about time i change the valve stem seals in the poor old Soarer. My question is - does anyone know if the head needs to be removed from the block to fit them or can they be installed without "too much" hassle??
My car is going in for its dental checkup soon and as I already have the seals I thought the mechanic could put them in for me while its in the shop, i'd prefer to save a bit of dosh on the labour if possible and do it myself if the head needs to be taken off (add labour cost here!)
Any info would be appreciated gents
Cheers
Dan

Hey, You dont need to remove the head but you will need a special tool to keep the valves closed. Ummmm yeah thats all I think.
Thankyou

I can't say that I have done it on a 7M engine (mine need doing as well), but I have done it on a 18R-G and also a 265 Hemi.
You need a you beaut spring compressor (I have one from Snap-On and it is brilliant). If you have sufficient access to the springs, then you can use this. The only drama is then keeping the valves in the right position, and here is the dodgy part.
Whjat you do is get some nice NEW and clean nylon rope (that will fit through the spark plug hole), make sure the piston that you want to do is at the bottom of the bore, feed in as much rope as you can, wind the piston back up slowly by hand to close to TDC as possbile (without applying too much pressure), and this will hold the valves in place. Replace the valve stem seals, and replace the spings etc and repeat for each cylinder.
