Metallic Clicking noise on cold starts
 

I'm wondering if this is a common s2000 noise or if mine is telling me its unhappy.

When I start the car up in the (relatively) cold Hawaii morning :LOL:, I hear this metallic "clicking" noise. its not a card fluttery sound, its more of a click click click click which seems to happen with the RPMs of the car. I'm wondering if anyone had similar problems and what they did to fix it. I dont get excessive oil consumption, dont have smoke coming out from anywhere, oil always comes out clean, drain plug has no metal shavings, etc~ knock sensor also is NOT tripping. am I just being overly cautious?

I have this feeling its a valve tolerance problem/noise as I did do it myself (with some help + special tools from a honda mechanic).

If you guys got any ideas, lmk..thanks!

also, after it warms up, the noise quiets down but its still faintly there.

do another valve adjustment?

ya i have the same noise. Im pretty sure i need a valve adjustment

^thanks guys. Yeah, I would except I gotta pick me up a few specialty tools (valve adjust tool...yeah I know you can ghetto rig it but want a real one), good feeler gauges, and a good piston holding tool.

for those who valve adjust DIY: how did you check "top dead center" for the piston? the mech I had help me checked it with a piston holding tool..can you use crank timing marks?

First you line up the cam gears.

Do cyl #1.
Turn crank 180 degrees.
Do cyl # 3.
Turn crank 180 degrees.
Do cyl #4.
Turn crank 180 degrees.
Do cyl #2.

Once you see the valve train turning and opening / closing valves you see when you can adjust them when both sets of valves are free of the followers.

:hello:

^Ah. always with the good information. thanks spitfire!
