Valve stem seal replacement

[Carbonraider]

Looking at why my engine uses so much oil I have come to the conclusion that it's the seals that have given up.. As there is oil everywhere..

On the piston, in the itbs and also pissing out the breather..

So has anyone given it ago without the head off?

A friend of mine has a tool he uses on vauxhalls in his garage (vaux specialist) that looks like it could be a winner on the f4r..

Basically it pressurises the chamber pushing the valves out meaning you can remove the collets for the retainers etc..

I'd say it's a combination of things as to why it's using oil mate. The most common being cracked ring lands on the pistons. It could also be that the valve guides are worn, so I think you may be fighting a losing battle.

If it's pissing out the breather it's ring lands.
