Suspected cause

It turned out to be a cracked exhaust valve seat that would lift up out of the head a little bit as the valve rose, then be pulled down into the seat by the descending valve.

Suggestion

Changed oil, tried an additive to clean the lifters, compression and leakdown tests were fine, thought it might be a coil pack, swapped those around, but the problem didn't go away.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

'06 C4 26,000 miles When running, there is a ticking sound coming from the passenger side cylinder bank. Ideas? Thanks, Adam

POST 3Original post

That’s where the dreaded bore scoring starts, cylinders 5&6

POST 4Original post

I had much the same symptom on my '02 Targa, and went through a long list of hypotheses with my indy... The car would run fine until it got hot, then you'd hear the ticking sound like it had a stuck lifter. Eventually I started to get the occasional misfire on cylinder 3 and a check engine light which would self-clear on the next start. Changed oil, tried an additive to clean the lifters, compression and leakdown tests were fine, thought it might be a coil pack, swapped those around, but the problem didn't go away. Finally my Indy (Rob King - S Car Go Motors in San Rafael, CA - great guys, BTW) looked inside the cylinder with a bore scope. It turned out to be a cracked exhaust valve seat that would lift up out of the head a little bit as the valve rose, then be pulled down into the seat by the descending valve. This was not an inexpensive fix, but I'm relating the story not because it was a nightmare, but instead because it was so unexpected. After running through the entire litany of usual suspects I feel very fortunate that the seat didn't come out all the way and drop onto the valve stem, getting caught between the valve and the head before being resoundingly smacked by the piston. Now all is back to healthy... Good luck- Drew
