Honda Civic Engine Too Noisy - Need Experts advise

    I'm glad to find this forum.

    My 1997 honda civic engine began producing too much noise after it
    went through a major repair when it overheated over a year ago. During
    the first few weeks after the car was fixed, i could still hear the
    engine noise to be normal. But after several weeks later, i started to
    hear loud noises from the engine valves (i could hear the sound like
    tikitikitik!!!). I went back to our shop here and had the valve
    clearance adjusted to the original clearance. Good enough, it came
    back to the original and acceptable noise. BUT then again, after two
    weeks, the valve's noise came back which I could hear it even when the
    hood is closed and I am sitting at the drivers seat.

    The loudest noise can be heard in the morning when the car is started
    and when the car is in parking mode (A/T car); but it subsides later
    when i am in the highway. But still, the noise it produced when at the
    highway is too loud and irritating to hear.

    The valves clearance has always been adjusted by the mechanic but has
    not prevented in producing noise.

    What seems to be the problem with this car? Is this porblem related to
    the valves?
    The mechanic suggested to replace all the rocker arms, is this a
    proper solution to the problem?

    I really don't want to spend on something that I regret in the
    future.. I want to check here if the mechanic had the right hypothesis/
    diagnosis on the problem related to the rocker arm replacements.

    I hope you can be of help to me.

    Thank you.

    You overheated the engine? Very bad. Very damaging.

    I can think of a few things that would cause your current problem:
    1) Warped camshaft
    2) Warped head
    3) Damaged hardening on camshaft/follower surfaces

    Do the clearances keep opening up?

    It was a very unfortunate overheating event...
    Yes, the clearance keep opening that a warped camshaft gear in
    Can you please elaborate more on the warped head? Are you talking
    about the cylinder head? It was already been 're-surface or flatten',
    the mechanic said.

    Appreciate your reply. Thank you.

    It's possible the camshaft is warped. A machine shop can check it for
    true. Your mechanic should also check the cam/follower surfaces for
    scuffing, indicative of damaged hardening. If the hardened coating is
    compromised, the cam or the relevant follower will wear out extremely

    If the head was warped and it was simply skimmed, that does not cure the
    warp, it simply eliminates warp from the head/block mating surfaces. The
    camshaft bearings will still be out-of-true and will get beat to death
    by the camshaft. The correct procedure is to have the head straightened,
    THEN skimmed.

    Overheating is severely damaging to the engine. You should find out
    whether or not the valve clearances are continually opening up and
    causing that noise.

    If compression and oil pressure are still good, you may want to consider
    a replacement head, which is cheaper than a whole new engine.

    Thank you very much for elaborating your answers.

    Yes, the valves' clearance would keep opening up and have to do tune
    up always.
    I'll have the camshaft check first if that's the case.
    If I have to replace the head, how much do you think the head would

    The head's going to be about $400 just for the part. Then there's the cost
    of labor, and possible replacement of the valve guide oil seals.

    I'd figure close to $1,000 for the job, if not more.

    Make sure your mechanic tests the block for corrosion, oil pressure and
    cylinder compression FIRST. No point in spending money on an engine which
    has corrosion, poor compression or oil pressure.

    Guy maybe oughta consider a second-hand engine for some $800
    plus cost of installation.

    Do I need the base or trhe vtec from the site? whats the difference
    between the two???

    Look at the numbers and letters stamped on the engine's
    front as it sits in the car. They should be a little below
    and to the right of the distributor housing as you stand at
    the hood release, facing front. They are about 1 to 2 inches
    high. Then match the letters and numbers with those shown
    under "engine" at the following site:

    About a third of these Civics were VTEC. The others,
    non-VTEC. You can probably google and find whether the LX,
    DX, etc. had VTEC or non-VTEC. Still, if you're in the
    market for a new engine, get the exact engine number-letter
    combination from its side.

    VTEC engines have one set of cam lobes for high RPM; another
    for low RPM. This allows more optimal intake and exhaust
    valve timing, since the timing needs of the engine for best
    (most fuel efficient) operation vary greatly from low to
    high RPM.

    Wikipedia has more.
