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?
Regards,
Michael.

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
cold.

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.

Cool trick, Mike!

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,
Mike.
