Hi, my 1.6L 4-cylinder Civic often makes a "clicking" noise, especially
when under load in too high a gear. Sometimes even at the "correct"
gear, when accelerating.

Is this pinging, pinking, tappet noise, detonation, spark knock, etc?
I've searched the posts, but I'm now more confused. Some people say
"pinging" is the same as tappet noise, which is harmless, while some
say pinging = detonation, which is bad.

So which is it, really, and what could be causing it on my engine?

Thanks!

 

"Pinging" is different from tappet noise. "Pinking" is the British variant.
Detonation is potentially bad. I have seen it break connecting rods. Spark
knock is another name for it. Which model year is your Civic?

Potential causes are maladjusted ignition timing, too low octane fuel, and
carbon deposits in the combustion chambers.

It's a 1995 model. I check/adjust the timing every week or so, no
problems there. Have noticed the 'pinging' even with premium fuel.

Given that it's noisiest when under load and the gear is too high, is
it more likely to be tappet noise, pinging or knock? How can I tell?

One hears tappet noise at idle. This is most likely pinging. Why would you
check/adjust the timing every week? Are you sure that you are doing it
properly? If you retard the timing a few degrees, then take it for a test
drive, and the noise is gone, then you would be pretty sure that it is
pinging.

How loud? Some Hondas use light pinging as an indication that engine
tuning has just passed the optimum detonation timing. The 05 HAH even
sounds like it's farting sometimes. If it's loud or constant I'd check
the spark plugs for damage and make sure that the intake manifold is the
right temperature. If there's an EGR valve, make sure it hasn't clogged.

I have been living with this intermittant clicking in my 91 Civic now
for almost 3-4 years. In my case, it is not the lifters (tappets), or
engine knock/pinging. My engine timing is fine too. (I assume your
remark about adjusting timing every week is a typo?).
The clicking comes from either some solenoid attached to the firewall
(a part of the device tray?), or maybe the injector solenoids. I just
do not know.........
One has to have really sharp hearing (most of my passengers cannnot
hear the clicking) to hear this annoying click. In my case too, it
comes on occasionally, even when I am cruising at highway speeds. Grade
of gas does not matter as you say.
The car drives fine, and does 39-41 mpg on highway. (I have been to the
dealership once, just to get this sound diagnosed.........unfortunately
none of the mechanics could hear it).
My low-tech (self-defeating?) solution.......just lower the driver side
window a crack whenever the clicking appears.......then you cannot hear
it anymore.......
If you find the culprit please post......in the past, there have been
posts by others in this newsgroup on this mystery clicking as
well.......but no one is any-the-wiser.....
