Hi There,
Im going to be changing the valve stem seals on my 1.6 pinto head. Ive heard there are two types? Some called tp hat? Not really sure which ones are best for this?
Also will a manual valve grinder stick be okay for grinding the valves in?
Cheers

If you only have single valve springs any old seal will do
CVH ones are narrow and used for double valve springs
Sucker on a stick is fine but hard work, I cut it in half and use a reversable battery drill.
