Tappet noises in D16 non-Vti Civic

[Nick.]

I get a tappety noise when the car is cold. (This is a metallic clicking sound at half the crankshaft speed). When it warms up it the sound goes away.
I adjust the tappets and the sound goes away - but returns a couple of weeks later.
Why is this? I am adjusting the tappets to factory spec.

The car is a EK Civic manual with non-Vti engine

Any help would be appreciated.
Rgds,
Nick

My guess is that the bolts are loosening up after you've driven around for a while after adjusting the clearances. Did you overtighten or undertighten the bolts? They should be just snug, not overly tight but right enough so they don't loosen up whilst driving :O

my tappets are a little noisy and there all spot on to factory settings. Dad did them for me hes a mechanic Just somthing you got to live with :(. Although having said that you can only really hear mine in drivethroughs,garages etc.

Are you guys sure your engines aren't pinging? Using good fuels?

kinda happens to mine too..
to me it is bad fuel.
but its over time.
last owner used 92
i started to use 95.
with valve lubricants, upper cylinder lubricants free noisy tappets .. etc etc..

it fixed it actually ..
still has a slight knock at cold though.
bit more maintenance here and there .. and it should b fine.. =]

Yes, I know what pinging is and this noise is definitely not it.

your car doesnt ping till under load tappets are noisy all the time on the spot
