never had the head off a t5 mate but i cant see how without the head off.
ive recon'd quite a few heads and the valves have to come out for the valve seals to be pressed out.
in my experience (for what its worth) its the valves that wear b4 the seals anyhow.

Volvo dealers seem to think it can be done without removing the head at a cost of around £600!!!!! Compressed air and a special volvo tool.

I would guess they are blowing compressed air in through the spark plug hole, to keep the valves closed whilst they get the springs off and change the seals.
Technically do-able, but only by the very well equipped. (Stop sniggering Moppy!)
funny my volvo dealer said head off!!!!!!Originally Posted by Green T5R

How do you know its the stem seals?, I have serious smoking probs at the moment(with the car,not me) and I tought it may be the stem seals. Having spoken to several specialists I was told the tey've never had to do any on an 850 yet!, having said this mine is booked in for Friday to be diagnosed.
high probability it is the sem seals as there is a plume of blue smoke at first pull away
where the oil has collected behind the valves while standing overnight and no visible signs of smoking when driving

i remember doing the old escorts, used to get the piston to top dead centre, then push the spring down with special tool, remove collets, take spring off, renew seal
in the true haynes manual style, refitting is the opposite of removal...lol
book time for seals is 9.3hrs, takes 4.7hrs to do camshafts and cam cover, if you have gone that far, may as well take the head off and do a proper job
yer but there are problems with head gasketts when they have been changed or so i have heard .... so would rather leave it in situe

I had my head gaskette replaced about two years ago now and I've not had any problems with it since.
not had many problems with new head gaskets, make sure head is level, if not, it will need skimming, both faces need to be very clean, and make sure nothing is in the head bolt holes in the block.
I always start the car up with no water in, after doing head gasket, let it tick over until the manifold becomes unbearable to touch, let the engine cool down before filling with water, this helps the gasket seal
ahhhh thats a handy hint cheers

It should be possible to make the 'special tool' with an old spark plug, mig welder and airline connections. I think Sealy sell similar.
One advantage of taking head off is being able to lap valve seats in, if the stem seals have expired then the valve seals would benefit from a freshen up. Agreed it could be a can of worms though
i think the spring compression tool is gonna be the worst bit
the compression for the cylinders c u can use a leak down tester

True. But it takes a LONG time. Well, it does it you're used to 8 valve engines!
Correct diagnosis however in relation to changing them without removal of the head....I doubt it. I did see somewhere on the net about someone doing it without removing the head (not on a volvo T5 thou). If it could be done then you would defo need specialist tools and lots and lots of patience and small hands, oh and a regular flow of tea!!!
Do it properly and get the head off, you can get a knew gasket, lap the valves in...will run like a dream when its finished
