Alright. I have a 97 gsr with 130,xxx km on it. about 2 weeks ago i noticed a very noticable rapid jingling sound coming from my engine kinda high pitch like something is loose in my valve train. I can hear it at 3000rpm all the way up to redline. And its on both accel and decel, so its not detonation. i always put 92 octane in.
Could it be a valve lash problem. But its not a ticking sound. it did get louder this past week and im worried it might be something serious.

you can hear it both inside and outside the car. Has anyone had this problem b4?

thx
