Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

I have read through all the posts on this subject but no info on my symptoms. I have a 02 C2 and at start up I hear nothing for the first minute or two, after that a loud ticking can be heard at idle, at 1400 rpm ticking is gone I haven't seen any info on "after" startup only noise "at " startup and no info on the rpm ranges it can be heard either any thoughts?

POST 2Original post

Any doubts,, time for a full top and bottom bore scope. Just get it over with.. Nothing on these motors gets better it seems, once it starts making noise..

POST 3Original post

I suggest you put your phone on the ground under the engine banks and record the ticking sound and post it.

POST 4 / ORIGINAL POSTEROriginal post

I used my stethoscope on all cylinders and 1,2,3 had ticking noise at 2000 rpm no noise at all if it were bore scouring wouldn't the noise be there throughout rev range? Again there is no noise at cold startup.

No. Based on the stage of scoring, the noise can vary in rhythm and tone. If in doubt, scope it out- period.

POST 8 / ORIGINAL POSTEROriginal post

Alright I'm going to borescope it! I'm afraid of it though cause Oct. 3rd I finally get my first track day that I've been dreaming about since I was a little kid and the results could make or break this life long dream of mine along with my bank account if I need a new engine! Well that's my sob story, I'll get back to you all with the results.

POST 9 / ORIGINAL POSTEROriginal post

I finally had it checked out and I have a bad cat so I ordered new cats not cheap but better than a new engine!

POST 10Original post

Bad cats are the worst, I once had a cat that was so bad even the dog was afraid of him!

POST 11Original post
