LASH ADJUSTER TICKING (FIELD FIX CLEANING PROCEDURE)
DESCRIPTION:
It may be necessary to clean the rocker arms of 1995-98 Accent SOHC engines which experience a ticking/collapsed lash adjuster condition, Vehicles that have received less than specified oil changes are likely candidates to require this procedure. A small particle (the size of a grain of salt) in the oil system may plug the rocker arm oil feed passage to the lash adjuster. Follow the procedures to properly clean the rocker arm(s).
CLEANING PROCEDURE:
CAUTION: Wear safety goggles while performing this cleaning procedure.
1. Remove the rocker arms from the rocker shaft, making sure to keep them in order. (See appropriate Shop Manual for removal procedures).
2. Spray or dip the rocker arm in solvent.
3. Blow compressed air through the rocker arm as shown:
A. Place the rubber tip of a safety type blow gun into the lash adjuster bore.
B. Place your finger tip over the vent port on the top side of the rocker arm (this will force the air through the oil passage back to the rocker shaft). Use a small piece of rubber or other soft material between your finger and the vent hole to prevent injury.
C. Blow the compressed air into the lash adjuster bore to dislodge any particles in the oil passage (the particle will shoot into the bore for the rockershaft).
4. Spray the rocker arm oil passage with spray solvent using an applicator tube. If the passage is clear, the solvent will squirt into the lash adjuster bore.
5. Reassemble rocker arms per instructions from the appropriate Shop Manual.
