Just wondering if there are any manuals or guides on the removal process of valve stem seals on the H22A1?

My BB1 Prelude is blowing a far whack of smoke, so I thought after this oil change (which will include a trade strength oil system flush and about half a bottle of Lucas Oil stabiliser), if that doesn't fix the problem, I'd have a crack at the valve stem seals.

Thanks guys,
Russ.
