    Hi All,
    I have a 1995 Honda Civic GLi (D15) and when I start it in the morning
    the engine is quite noisy. It produces a ticking noise and goes away
    after 5 minuets then the car is fine. It only happens when the car is
    cold, once it has been driven it will not do it again during the course
    of the day. I have adjusted the tappets and it has made no difference.
    I also notice the car lacks in power between 3k rpm and 4k rpm then it
    comes back at 4.5k rpm. Any suggestions on this problem?

  2. The ticking noise might be a broken exhaust manifold stud or bad exhaust
    manifold gasket. As the engine and manifold heat up, the gap closes and you
    don't hear the exhaust leak any more. The telling clue if it is indeed a
    manifold leak is that the ticking gets louder as you open the throttle. It
    is a ticking instead of a roar because it is a tiny leak of the raw exhaust
    from one cylinder.

    If that fits your symptoms, my favorite way of looking for exhaust leaks is
    to connect a shop vac to blow air, run it a minute or so to blow the loose
    dust out of the hose, then duct tape the hose to the tail pipe. This will
    let you feel for the leak around the manifold gasket when the engine is

    For the power problem I will hazard a guess the ignition timing may be the
    culprit - only a guess.

    I like that exhaust leak tester idea... I wish I had used that when I
    worked on cars a few years ago.

    Hi Mike,
    The answer you gave me sounds like it could be the problem, When I first
    start the car you do not notice it as much but once I take off and
    the car is under load it is more noticeable. This problem is common in
    1986 holden commodores (Nissan rb30 motor) where they snap manifold
    bolts. I have been told that you can also check for these symptoms by
    spraying some oil on the exhaust manifold and looking for smoke at the
    tail pipe as the oil should burn and come out the other end. Do you
    think this will work as I do not have a shop vac.
    As for the power problem I have not checked the ignition timing yet, but
    I did notice that my distributor cap had heaps of corrosion on it so I
    cleaned it and it made a small difference, I will check the timing next
    and see how I go.
    Thanks for the help,
