valve oil stem seals

[glanzatd04l]

right lads I know this has been asked before but im getting mixed answers,
im replacing the valve oil stem seals on my ep91 but the question is what side does the brown seals and greyish seals go?

on here people say brown to inlet and grey to exhaust but on ukstarletowners site they say brown to exhaust and grey to inlet.

yes the outer diameter is the same but the iner diameter is different, the brown seal has a bigger inner hole.

why ????? the valves diameter are identical

 

[aidan]

Maybe the exhaust valves get hotter which will expand them more letting them needing the bigger hole

Thats why the difference in color. So you could identify which is exh and which is int.
