What is the method for replacing valve stem seals without removing the cylinder head?
1 Answers
You can use a thin rope to suspend the valve. If necessary, remove the spark plug of that cylinder and introduce high-pressure air through the spark plug hole to hold the valve in place for valve stem seal removal and installation. Normally, the engine cylinder head needs to be removed, and after holding the valve in place, the valve stem seals can be replaced and other operations performed.
