so one day after driving my s2000 i noticed a ticking noise coming from the engine.. notgood.jpg so went out and had the car looked at. dropped oil pan and it was clean no shavings and rods and bearings were good. had my valves adjusted they were off by a bit but that wasnt the issue. now im left wondering what it could be... had the oil changed and that didnt do anything. the noise seems to get louder when i rev the motor and ive attached video of car when the motor was warm. could this be tct? im not familiar with the sound and i need some help finding this out.

youtube video:

 

Yikes, that doesn't sound good. Maybe start by pulling the accessory belt off to isolate from the various pulley's? Good luck OP and hope Billman chimes in....

 

 

that TOTALLY sounds like bottom end, bearing, trust, something..... But weird you have no metal shavings?

Maye loose rod bolt? idk, that odd.

U pull the vtec sel to check the screen?

 

found nothing it was clean. even after i changed the oil before dropping the pan i found nothing. the idling is just fine and the its not acting weird aside from the noise. car starts up just fine. will post video of the cold start ticking.

 

here is a video of the ticking after i do a cold start. car came on fine no metal grinding noises and started right up.

 

ADDITIONAL INFO: i have NOT changed the TCT. i did some snooping around and heard these motors are notorious for the TCT making a noise. although, idk if this sounds like a TCT issue..

 

I really don't think this is a TCT noise...for your sake I hope it is.

 

 

I listened to this last night, curious to see what it is.
