Is there anyone out there that can explain to me why my 02 r6 with 3500 miles on it sounds like it needs a valve adjustment.....it ticks all the time whenever it wants.....comes and goes....especially on deceleration....HELP!
not really.....the last service that I had was the 600 mile service otherwise I change my own oil. The dealership told me originally that it was normal....but i know enough to say it doesn't sound right
My '03 is 500 miles old now and it ticks too, i've only noticed it under 6k revs as i'm still running it in but i'm guessing it's natural. It doesnt sound great but isnt awful. I'm going to mention it to the dealer at the 600 mile service and I'll post on here what they say.
The CCT just keeps tension on cam chain to ensure it from stretch, and to keep it in time. If it would get really bad, the chain can slack too much and cause stretch under heavy acceleration. It can also cause the cams to skip time. This is rare, but internal engine damage can be very severe if cams skip time, or if chain breaks. Expensive to repair also.
CCT's very commonly go out on pre '03 honda F's. A friends '02 F4i went through 3 last summer in 2400 miles. If you hear a F4i with a bad CCT, you'll remember distinctively what they sound like! Yet i haven't heard of honda having many problems with time skip, or breaking chains, so this goes to show how rare it can be. I'd say about 3 of 5 Honda 600 F's i hear have bad CCT's!!
