How To Remove Valve Stem Seals.

[RTA 13B]

So I would like to know a couple of things in regards to removing the valve stem seals on a RB25DET engine.

1) Do I have to remove the head off the block?

2) Do I have to remove the valves out of the head?

if no to both of these then...

How do you remove the valve stem seals?

I have used search and had a look at other Skyline websites. So I am hoping someone on here might have done this already.

Can anyone help?

You can do them with the head on the block, but you will need to pressurise the cylinder with the valves shut to stop them dropping in.

Thanks Mik. We had thought about this, however rather than just going ahead blindly thought it better we ask around.

So just get each piston at the top change their valve stem seals? Cool.

Will be done this weekend. Thanks for your help.
