been getting a puff of smoke form exhaust on start up for about 2 seconds then followed by a click sound then all is fine . Believe this could be valve stem seals :-\. Unless anyone has any other suggestions ;)
Does anybody have any advice on stem seal replacement (can this be done without removing heads ??)
Thanks Noel :y

There's a bit more to it than that.
First you've got to have a method for keeping the valves closed while compressing the valve springs. This could be compressed air through a special adaptor into the spark plug holes, or more 'ghetto'; rope fed into the cylinder down same hole with piston low, and then the piston moved up 'til it will go no further against the rope.
Then you need a tool that will push each top spring retainer downward far enough to get the valve collets off the stem, releasing the top retainer, giving access to the seal. If you're a bit handy you may be able to lash up some sort of lever system DIY.
Not a quick and easy job by any means.

Mines been merrily doing it for 3 years ;) IIRC Vauxhall say it is not a problem unless you start using more than 1litre of oil per 1000 mile. :y

Had thought about trying Forte seal conditioner to see if that helps :-\, but im sure someone will be along who has tried some maybe ;)
