Name that noise!! Engine tick
Background:
Been making this noise since I got it randomly, also seems worse in colder weather.
Only at idle, and only after sitting at idle for a while.. Passenger side.
Goes away with throttle addition.
Car runs really great, so smoke no oil or coolant loss.
Oil was changed 2k miles ago with 0w40. And filter dissection has been clean since I bought it. 102k miles on it now.

Thoughts?
Loose spark plug?
Oil too thin?
Water pump?
Exploding metal death even though it's been fine for 12k miles and hasn't gotten worse or showing any negative effects other than sounding like a jalopy?

Ordered a boroscope camera. Interesting development though. Added seafoam to the oil, after a drive home from work and lots of idling the noise is gone... So spark plugs seem less likely.
Will start researching bore scoring.

Really hope it's just a sticky lifter but the sound is quite solid and dull in the video..could be just the recording though.
More importantly the rhythm of the knocking is close to one per ignition (i.e., ~6-8 times/sec @ idle).
Another forum member "Van" has a cylinder scoring and this is his video

If you read all the threads for 'ticking' the consensus is bad,real bad.
I did read most of them because I had that issue. I was convinced it was lifters until the tick became a knock.....I hope your Seafoam works.
