Strange issue - need help
Good evening everyone!
I haven't been on here since I sold my Daytona, but I'm working on a 2015 S3 and need a little help.
Here's the story:
Owner was riding up in the foot hills of Denver when the bike seemed low on power. He pushed on and then heard what he described as a loud cam chain noise, but lower in tone like a spun bearing. He pulled off the road and shut it off. After waiting a bit he tried to start it, heard the same noise with a rough idle, and then it died. He reported that he then waited another 20min and started it again. He said that the noise wasn't there but it was almost as if it was running on 2 cylinders. He got it back to his place, drained the oil, and then brought it to me. I put more oil in and started it up... It's running great!
Here's what I've done so far:
Checked the oil for flakes or a metallic sheen. Oil looks okay
No excessive wear on the timing chain. I'm going to stretch test it.
No excessive wear on the cam journals so I doubt there's a problem with starvation
No rattles, no knocks.
What am I missing?
