200tdi valve stem oil seals?

<< < (2/2)

L90OOK:
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)

ferret:

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:

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).
