Removing the Valve Keepers/locks
Part of Lesson Plan: **Remove and Replace a Valve (updated) by Steve Nagle
Activity Overview / Details
Depress the valve spring compressor. If the valve compresses, locate the two tapered valve keepers/locks and remove. If the spring does not depress, it may be hanging up on the old valve oil control seal. While compressing the valve spring, tap lightly on the valve compressor fingers with a soft faced hammer. This will break loose a stuck valve retainer.
