Hi have been told it maybe worth me changing the valve stem oil seals on my 90 ,is it easier to take head of and do on the bench or can they be done on the engine .
 
why ? smoke on start up or other symtoms
as long as you have piston at tdc you can remove the collets and springs on that cylinder plus its corresponding cylinder ie 1 and 4 and 2 and 3, you can make or buy a lever for compressing the springs ,similar to this

Using a torch with the rocker cover off, you will most likely see the seals have worked their way up the valve stems, Ive seen a few like it now, even my spare head has 4 of the seals off their seats.
 
Hi
Thanks for all your advice im going to whip the rocker cover off at the weekend and have a look.
And thanks for links to tools
