Camshafts & Valve Lash Adjusters Removal & Installation: Installation

WARNING: This page is about a different car, the 2004 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Don't turn camshafts or start engine (i.e., valves should not be operated) for about half an hour after reinstalling hydraulic valve lash adjusters and camshafts. As it takes time for valves to settle in place, operating engine within half an hour after their installation may cause interference to occur between valves themselves or valves and piston.
  • If air is trapped in valve lash adjuster, valve may make tapping sound when engine is operated after valve lash adjuster is installed. In such a case, run engine for about half an hour at about 2000 to 3000 rpm, and then air will be purged and tapping sound will cease. Should tapping sound not cease, it is possible that valve lash adjuster is defective. Replace it if defective.
  • If defective adjuster can't be located by hearing among 24 of them, check as follows.
    • Stop engine and remove cylinder head cover.
    • Push adjuster downward by hand (with less than 200 N (20 kg, 44 lbs) of force) when can crest is not on adjuster to be checked and check if clearance exists between cam and adjuster. If it does, adjuster is defective and needs replacement.
  1. Before installing valve lash adjuster to cylinder head, fill oil passage of cylinder head (1) with engine oil according to the following procedure.

    Pour engine oil through oil holes (2) and check that oil comes out from oil holes (2) in sliding part of valve lash adjuster.

    Perform this check on both intake and exhaust sides.

  9. After applying oil to housing bolts, tighten them temporarily first.

    Then tighten them by following sequence ("1" - "19") as indicated in the figure. Tighten a little at a time and evenly among bolts and repeat tightening sequence 2 or 3 times before they are tightened to specified torque below.
