Iv'e got a 97 accord se. Knocks when cold, not ticks. Like a little diesel. It goes away somewhat when warm. Very intermitant.Maybe cam bearings? does it under load sometimes sometimes not. What can I do on my own to find out if its top or bottom?

 

I've had the same problem on a 97 Civic and am now having it on a 2000 Accord EX. Both were 4cly models and both had a mild ticking sound when it was cold. The sound would go away as soon as the engine made it up to operating temp. However, I didn't start noticing this until the engines started approaching 100K miles. Had the valves adjusted on both and no change. Tried additives, tried cleaners (thought I had a clogged oil jet). No luck. Best bet always seemed to just let it warm up before driving on cold days.

 

Why the hell are bringing back all of these old ass threads and copy/pasting your answer in all of them? Please stop.
