Replacing broken valve springs and defective valve stem seals on VTEC models requires the cylinder head to be removed first. Remove the camshafts and cylinder head, then refer to Parts General and overhaul of the engine of this Chapter and, acting in accordance with the instructions given in the relevant Section, remove the valves, valve springs and oil seals.
On models not equipped with a VTEC system, the components in question can be replaced without dismantling the head. The procedure is described in VTEC Systems - General Information and Component Health Check Parts Engine repair without removal from the car - Civic models of this Chapter.
