200tdi valve stem oil seals?

[ferret]

Can they be changed at the same time as fitting new springs etc without removing the head?

[extreme90]

the head needs to be removed to change the springs aswel as stem seals
unless you have a secret way of holding the valves in place whilst compressing the spring enough to remove the collet  :?  :?

ive heard of string being stuffed into the cylinders before now to stop the need of having to remove the head  :lol:

Thats  a shame as i wanted to change the valve stem caps and springs and seals while i was at it as mine are makeing a right racket now.
Are there any good links to look at about 200tdi head removal that you know of.

[extreme90]

errm common sense ?
seriously do not look at the haynes man, itll scare you into thinking its hard when its a doddle
drain coolant off
remove the inlet manifold completely
remove front zaust pipe, then unbolt the manifold and pull the whole lot off to the side
undo injectors,leak off rail and glowplug wire
undo heater matrix pipes
remove rocker cover
remove any relivant breather pipes
then undo all the kin tight bolts
and as they say..off with his head  :lol:  :lol:

of course thats very basic description of what is involved, but its o so easy  8)
there are some things that im bound to have missed somewhere, but there pleant here to give advice and help over fone if needed  8)

I'll second that
Having just replaced my 200tdi head it is a doddle.  Can be done easily within a day.  Just be methodical about it  :D  8)

I have a valve spring compressor kit for a Ford pinto engine which allows removal of springs and change seals without removing the head. The kit includes an adapter for the spark plug hole to which is attached a compressed air supply. The idea being the air pressure holds the valve in its seat. 10 years later, I have still yet to try to see if it does what it says on the tin :D But maybe the same principle can be used on a diesel :?:
Have also heard of the rope trick.

Another one from Ford, I don't remember if it was the CVH or Kent though but it was a tool that went in through the sparkplug hole with a sort of ball on a stick afair that you could manipulate from above the negine to hold the vlave in place.  Havn't seen one for years though.

Actually thinking on it was probably the CVH as the other tool was a rocker valve spring compressor that bolted to something on the head, probably the rocker post.

Heard of the rope trick for straightening bent valves too but using copper wire (PVC covered is best).
